+Hamarsoft (R) 86BUGS list, supplemental programs.
+The 86BUGSxy archive should contain the following files:
+
+- 86BUGS.HLP    Microsoft QuickHelp hypertext version of the list.
+- 86LISTnn.LST	The text version of the 86BUGS list.
+- FILE_ID.DIZ   An upload description for Bulletin Boards.
+- iAPX122.ZIP   Testing software archive from Chris Lueders, Germany.
+- INFO.EXE      CPU info program with various information regarding your
+                processor.
+- STAT.EXE      Pentium Processor Pipeline & features performance monitor.
+
+Both STAT and INFO are provided by Christian Ludloff. These programs are
+based on his article in the german C't Magazine of November 1994 (issue 11).
+
+iAPX122 is a testing program provided by Chris Lueders. It tests for some
+of the bugs mentioned in the 86BUGS list.
+
+All programs are provided with this list as a service from Hamarsoft to the
+readers of the 86BUGS list. Hamarsoft does not accept any liability for
+these programs whatsoever.
+
+The 86BUGS list is also distributed with Ralf Brown's Interrupt List.
+
+[86BUGS.HLP has been omitted for space reasons, and the other files except
+for 86LISTnn.LST are located in INTERrrD.ZIP.  86LISTnn.LST has been
+renamed to 86BUGS.LST for compatibility with hypertext conversion
+programs expecting that name.]

+			   COMBINE.COM v2.10
+			     by Ralf Brown
+			     22 March 1998
+
+COMBINE.COM will concatenate all of the partial files in the interrupt
+list distribution archives into a single master file for interrupts and
+a single master file for I/O ports, which is required by some viewers
+and hypertext conversion programs.
+
+To use COMBINE, just change to the directory into which you extracted
+the distribution archives, and type
+
+	COMBINE {dir}		(for interrupts)
+   and then
+	COMBINE -p {dir}	(for ports)
+
+where {dir} is the name of the directory in which you want the combined
+list to be stored (typically, you will type "COMBINE ." to store the
+result in the same directory as the individual sections).  If there is
+not enough free disk space to hold both the individual sections and the
+combined list, you will be told and given the option of running COMBINE
+again with an option to tell it that it should delete each section as
+it is added to the combined file:
+
+	COMBINE -d {dir}
+
+COMBINE will skip any missing sections of the interrupt list; if at
+least one section other than INTERRUP.A (PORTS.A with -p) is present,
+it will stop as soon as the last section has been processed (otherwise,
+it will continue trying all names through INTERRUP.Z/PORTS.Z).  On
+completion, it sets the combined file's timestamp to be the same as
+that of the last of the individual sections.
+
+System Requirements:
+	DOS 2.0+ or a DOS compatibility box
+	64K available RAM
+	a copy of the interrupt list :-)
+	sufficient free disk space (~360K with the -d option)

+			iAPX 86 Interrupt Primer
+			------------------------
+
+			     by Ralf Brown
+				 12/87
+		    Updated 6/88, 4/90, 9/92, 1/97
+
+
+What is an interrupt?
+---------------------
+   An interrupt is a hardware signal that tells the CPU to temporarily
+   stop what it is doing and go do something else.  Without interrupts,
+   the CPU would have to constantly check for external events; with
+   interrupts, the CPU can work on something else and still respond to
+   an event as soon as it occurs. 
+
+   CPUs typically have an instruction to disable interrupts for use
+   when a section of code has to run without being disturbed by
+   external events.  Because of this, most CPUs also have a special
+   interrupt called a Non-Maskable Interrupt (NMI), which is responded
+   to even when all other interrupts are disabled.  The NMI is used to
+   signal calamities such as memory failure or imminent power loss.
+
+Why so many different interrupts?
+---------------------------------
+   The 8086 family of processors has the ability to recognize 256
+   different interrupts.  They also have the ability to let a program
+   invoke any of these interrupts with a special instruction, known as
+   a software interrupt (as opposed to a hardware interrupt which is
+   signalled from outside the processor).  Software interrupts are
+   treated just like hardware interrupts, except that they are never
+   disabled and do not result in an acknowledgement to other chips in
+   the computer.  The software interrupt instruction on the 8086 family
+   is called INT, and is given the number of the interrupt.  Thus an
+   INT 21h instruction invokes interrupt number 33 decimal.
+
+   Other processors also have software interrupts, though they often
+   use different names, such as the Motorola 68000 family TRAP
+   instruction, the Intel 8080 RST (ReSTart) instruction, or many
+   mainframes' SVC (SuperVisor Call). 
+
+   Since a program can invoke an interrupt by number rather than by its
+   address (as it has to in calling subroutines), interrupts are a
+   convenient way of providing services without having to recompile a
+   program whenever the address of the code providing the service
+   changes.  This also allows a user program to enhance the services
+   provided by directing the interrupt to itself.  These enhanced
+   services can then be made available to other programs.
+
+How does an interrupt work in real-address mode?
+------------------------------------------------
+   The 8086 reserves the lowest 1024 bytes of memory for a table (IVT,
+   Interrupt Vector Table) containing the addresses for each of the 256
+   possible interrupts.  When an interrupt occurs (hardware or
+   software), the processor multiplies its number by 4 and looks at the
+   resulting memory location to find the address of the piece of code
+   which handles the interrupt.  It then places the current address in
+   the program and the processor flags on the stack, and jumps to the
+   beginning of the interrupt handler.
+
+   When the interrupt handler finishes, it invokes a special
+   instruction to return from the interrupt.  This instruction takes
+   the previously saved flags and program address off of the stack and
+   places them back in the appropriate registers in the CPU.
+
+   The interrupt handler has to be careful to preserve any registers
+   that it uses which are not used to communicate results to the
+   program that invoked the interrupt.  If the interrupt can be
+   triggered by a hardware interrupt (only certain ones can on IBM
+   PC's, XT's, and AT's), then the interrupt handler has to preserve
+   ALL registers, since the interrupt could have happened anywhere.
+
+How does an interrupt work in protected mode?
+---------------------------------------------
+   The 80286 and later processors can also operate in protected mode,
+   in which case the interrupt handling is somewhat different.  First,
+   the interrupt table consists of eight-byte descriptors instead of
+   four-byte addresses, and need not be located at physical address
+   zero, nor contain the full 256 entries (the address and size of the
+   Interrupt Descriptor Table (IDT) may be manipulated with the LIDT
+   and SIDT instructions).
+
+   Second, in protected mode, the descriptor for an interrupt number
+   specifies HOW control is transferred to the interrupt handler.
+   Three types of transfer are possible: Interrupt Gate, Trap Gate,
+   and Task Gate.  The first two types transfer control to a handler
+   running in the same process as the active program, while a Task Gate
+   performs a complete context switch in order to invoke a handler in
+   a different process from the active program.  Interrupt and Trap
+   gates are identical except that an Interrupt Gate will clear IF
+   and thus disable interrupts, while a Trap Gate leaves IF unchanged.
+
+How does an interrupt work in virtual-86 (V86) mode?
+----------------------------------------------------
+   The 80386 and later processors provide a virtual-8086 mode which is
+   a protected mode that appears to software to be the same as Real
+   mode.  Because it is a protected mode, however, interrupts and
+   various other actions that potentially affect system integrity do
+   not execute directly, but instead invoke a supervisor program running
+   in standard protected mode.  Thus, whenever a program running in
+   V86 mode invokes an interrupt call, the CPU switches to protected
+   mode and transfers control to the interrupt handler specified by
+   the protected-mode IDT, rather than the real-mode IVT.  The
+   supervisor program may handle the interrupt call in any way it
+   likes, but typically switches the CPU back into V86 mode and jumps
+   to the address specified in the real-mode IVT (a process which is
+   known as "reflecting" the interrupt).
+
+
+GLOSSARY
+--------
+API (Application Program[ming] Interface)
+   An API is the set of function calls and services that a program
+   makes available to other processes (applications).  Each function or
+   service has a set format which specifies the values to be supplied
+   by the caller and the values which are returned. Because of this
+   interface specification, the underlying organization of the function
+   or service can be changed without affecting the applications which
+   use it.  For example, the DOS INT 21h file access functions remained
+   unchanged between DOS 2.x and DOS 3.x, even though the internal data
+   structures and code organization changed significantly.
+
+IDT (Interrupt Descriptor Table)
+
+IVT (Interrupt Vector Table)
+
+NMI (Non-Maskable Interrupt)
+   Most external (hardware) interrupts can be disabled by the CLI
+   (CLear Interrupt enable flag) instruction when the CPU is executing
+   critical code that should not be interrupted, such as switching from
+   one stack to another.  However, there are some situations so dire
+   that the CPU must act on them immediately no matter what else it is
+   doing, even if it has disabled interrupts.  The Non-Maskable
+   Interrupt serves precisely this purpose, as it cannot be disabled
+   (masked) by the CPU.

+			    INTPRINT v3.11
+			    by Ralf Brown
+
+The INTPRINT program is hereby donated to the public domain, with the sincere
+hope that proper credit will be retained in all copies and derivatives.
+
+------------------------------------------------------------------------------
+
+INTPRINT.COM is a simple formatter for the interrupt list, both
+INTERRUP.LST and the other *.LST files.  Use this program to print only
+a portion of the list, prevent widow lines at the beginning of a
+function call, number the pages, boldface key portions, center the
+printout, or create a summary of the function calls.  After formatting
+is complete, the total number of pages is displayed on the screen.
+
+Usage:
+   intprint [options] intlist [[>|>>]outfile]
+
+where the options are:
+	-b    boldface the title lines, Return:, and Notes: by overprinting
+	-B    boldface by sending printer control sequences
+
+	-d    (duplex) print even/odd pages with different margins; suitable
+	      for binding the printout.
+
+	-e    assume printer is in elite mode (96 characters per line), and
+	      indent the output eight spaces to center the printout.  This
+	      is primarily for the default printer, as other printers may
+	      force the equivalent or override this option.
+
+	-ffile	create a file containing only the data structures described
+	      in the interrupt list.
+	      NOTE: you must put the filename immediately after the 'f'; no
+	      blanks are allowed.
+
+	-Ffile	filter the listing based on include and exclude strings
+	      in 'file'.  Only entries whose headers match none of the
+	      exclude strings and at least one of the include strings
+	      will be processed.  All others will be skipped.
+	      NOTE: you must put the filename immediately after the 'F'; no
+	      blanks are allowed.
+
+	-H    print a heading on each page indicating which interrupts
+	      are listed on the page
+
+	-iN   indent the output N spaces.  The output device is assumed to be
+	      at least 80+N characters wide.
+	      NOTE: you must put the number immediately after the 'i'; no
+	      blanks are allowed.
+
+	-I    assume the printer is capable of producing IBM character
+	      graphics.  Printers other than "default" may force this option.
+
+	-k    keep original divider lines instead of replacing them
+	      with all dashes.
+
+	-lN   print N lines per pages, overriding the printer-specific
+	      default.	Use 0 to omit page breaks (in this case, the
+	      reported number of pages and -r page restriction may be
+	      incorrect unless you also use -L); this can be useful if
+	      you only want to filter the list before processing it
+	      further.
+
+	-LN   assume N lines on a page.  If this is more than the number of
+	      lines to print on each page, INTPRINT will use line feeds to
+	      advance to the next page instead of form feeds.
+
+	-m    specify that the interrupt list is in multiple parts beginning
+	      with the named file.  INTPRINT will increment the last
+	      character of the name to get the next filename, and continue
+	      until it is unable to open the file thus selected.
+
+	-nN   assume N pages have already been printed, and start numbering
+	      at N+1.  This option allows you to create a properly-numbered
+	      printout even if there is not enough disk space to concatenate
+	      the parts of the interrupt list or hold a complete output file.
+	      See the examples below.
+	      NOTE: you must put the number immediately after the 'n'; no
+	      blanks are allowed.
+
+	-p    print the page number at the bottom center of each page
+
+	-Pname use control codes for the specified printer (-P? lists the
+	      supported printers).  The printer name may be given in either
+	      case and abbreviated to a unique prefix; use either dashes or
+	      underscores in place of blanks in the printer name.
+
+	-rN:M print only pages N through M.  The entire input is processed
+	      for use in -s and -f summaries (see below) even though only
+	      a portion is formatted for printing.  If filtering is enabled,
+	      (see -F), page numbers are based on entries selected by the
+	      filter file.
+	      NOTE: you must put the page numbers immediately after the 'r';
+	      no blanks are allowed.  When using -l0 together with -r,
+	      you must specify the appropriate page length with -L so
+	      that page numbers can be computed correctly.
+
+	-sfile	create a one-line-per-function summary and write it to "file"
+	      if -n is also given, the summary will be appended to "file",
+	      allowing a properly numbered summary file to be created even if
+	      there is not enough disk space to concatenate the parts of the
+	      list.  See the examples below.  If -p is also given, page
+	      numbers will be included in the summary.	If -V is also given,
+	      byte offsets for use by INTERVUE will be included.
+	      NOTE: you must put the filename immediately after the 's'; no
+	      blanks are allowed.
+
+	-tN   select typeface N for the chosen printer (currently supported
+	      only for the HP).
+
+	-Tfile	create a one-line-per-table summary and write it to "file"
+	      if -n is also given, the summary will be appended to the named
+	      file.  If -p is also given, page numbers will be included in
+	      the summary.  If -V is also given, byte offsets for use by
+	      INTERVUE will be included.
+	      NOTE: you must put the filename immediately after the 'T'; no
+	      blanks are allowed.
+
+	-V    indicate that the summary file is intended for use by INTERVUE.
+	      INTPRINT will output byte offsets that allow INTERVUE to jump
+	      directly to an entry.  Also forces -I.
+
+	-wN   (widow lines) search N lines from the end of the page for a
+	      good place to break.  The default is eight lines; the valid
+	      range is from 3 to one-half of the page length.
+	      NOTE: you must put the number immediately after the 'w'; no
+	      blanks are allowed.
+
+	-x    include Index: lines in formatted listing.  These lines are
+	      are excluded by default because they are intended primarily
+	      for use by hypertext converters.
+
+Options may not be merged; "-ep" is illegal and the "p" will be ignored.
+Use "-e -p" instead.
+
+The formatted result of the input file is sent to the specified output file,
+or to standard output if no output file is given.  Standard output may be
+redirected using the usual Unix or MSDOS redirection characters > or >>.  If
+you only want a summary file or data formats file, send or redirect the
+output to the null device ("NUL" under MSDOS, "/dev/null" under Unix).
+
+
+FILTER FILE:
+------------
+
+The filter file specified with -F is a simple text file containing
+include lines, exclude lines, and comment lines.  Both 'include' and
+'exclude' lines may be based on either a category code or a substring
+of the entry's title line.  Comment lines start with a hash mark (#) in
+the first column and are ignored.  The other valid command characters
+in the first column are:
+
+   >  unconditionally include any entry with the specified category letter
+   <  unconditionally exclude any entry with the specified category letter
+   +  include entries containing the specified string, unless unconditionally
+      excluded
+   -  exclude entries containing the specified string, unless unconditionally
+      included
+   i  include entries with the given category letter unless specifically
+      excluded by a '-' line
+   o  override '-' line and include entry anyway if it has the given
+      category letter
+
+Note that any category letters or selection strings must immediately
+follow the command character.  All spaces on '+' include and '-' exclude
+lines are significant.  Thus,
+	+ DOS
+will only match entries containing the four-letter sequence " DOS",
+while
+	+DOS
+will match any entries containing the sequence "DOS", whether or not it
+is preceded by a blank.
+
+If a filter file is specified, only entries whose title lines contain at
+least one of the '+' include lines (ignoring uppercase/lowercase
+distinctions), none of the '-' exclude lines, or whose category codes
+have been selected by other include/exclude lines, are processed.  Thus,
+a filter file must contain at least one include line, or INTPRINT will
+skip all interrupt entries and print only the non-interrupt text in the
+file.

+
+The x86/MSDOS Interrupt List
+	A comprehensive listing of more than 8500 functions available through
+	interrupt calls on IBM PCs and compatibles.  Includes both
+	documented and undocumented functions, plus lists of I/O port, CMOS,
+	and memory locations, far-call entry points, model-specific
+	registers, and system-management mode state save areas.
+	Current version: INTER61A (release 61, 16jul00)
+			 INTER61B
+			 INTER61C
+			 INTER61D
+			 INTER61E (utility programs)
+			 INTER61F (hypertext conversion programs)
+
+DVINT
+	An extract of the MSDOS Interrupt List containing the DESQview
+	and QEMM API calls.  Updated whenever there have been significant
+ 	additions to the DESQview/QEMM calls in the Interrupt List.
+	Current version: DVINT43 (06jun94)
+
+RBcomm
+	A DESQview-aware communications program which sports seamless DSZ,
+	PCZ, or PUMA/MPt integration for file transfers; ANSI/VT102, VT52, 
+ 	and AVATAR emulation (including 132 columns); speeds to 115200 bps;
+	a powerful macro language; dialing directory; ANSI music; and
+	more.  Runs in 65K with DSZ, 47K without.  While it works under
+	plain DOS, additional features are available under DESQview.
+	Current version: RBCOM346 (v3.46 29jan95)
+
+RBdualVGA
+	Use two color displays on one PC.
+	Current version: RBDUAL09 (v0.9 02jun96)
+			 DUAL093S (v0.93 source code, 11sep98)
+
+RBkeyswap
+	Exchange left control and CapsLock keys, as well as Esc and `/~.
+	Loads itself high, using just 64 bytes; needs only 128 bytes low
+	if no high memory is available.
+	Current version: RBKEYSWP (v2.0 22jun91; v3.0 included in AMISLIB)
+
+RBpci
+	Print out more than you ever wanted to know about the devices
+	on the PCI bus inside your computer.  All device-specific data
+	files are plain text, to let you update/customize them yourself
+	(updates for new chips which are sent to the author will be
+	included in the following release).  Includes full source code
+	for the program.
+	Current version: RBPCI119 (v1.19, 10jan99)
+
+SPAWNO
+	A replacement for the Turbo C and Microsoft C spawn..() functions
+	which swaps the current program to disk, EMS, XMS, or raw extended
+	memory while the spawned program executes, leaving less than 300
+	bytes in memory.  Also includes a variant for Turbo Pascal v4.0 or
+	higher.
+	Current version: SPWNO413 (v4.13 12dec92)
+	Price: libraries free, full source code $100.
+
+AMISLIB
+	Public Domain library (with full source code and five sample TSRs)
+	for creating self-highloading TSRs which may be unloaded in any
+	order.	Up to 256 TSRs created with AMISLIB may be installed
+	simultaneously, and TSRs can be as small as 128 bytes resident,
+	1.4K on disk.  One of the sample TSRs is a popup which accesses
+	DOS.
+	Current version: AMISL092 (v0.92 24sep95)
+
+DV-GLUE
+	DESQview API bindings for Turbo/Borland C (also mostly compatible
+	with MS C).
+	Current version: DVGLU172 (source & compiled) (v1.72 01oct95)
+
+DVKPOLL
+	"Poor man's version" of TAME.  Makes programs give up CPU time when
+	they are in an idle loop polling the keyboard for keystrokes.
+	Current version: DVKPOLL2 (18jun88)
+	Note: This program has been superseded by DVPTAME.
+
+DVPTAME
+	"Not-so-poor man's version" of TAME.  Tells DESQview to give the
+	remainder of a time slice away if the program is in an idle loop
+	polling the keyboard for keystrokes.  Uses 0 bytes of memory.
+	Current version: DVPTAME (04jun91)
+
+DVdevload
+	Load device drivers only in those DESQview windows which need the
+	services of the driver, reducing the pre-DESQview overhead and thus
+	permitting larger DESQview windows.
+	Current version: DVDEVL12 (v1.20 03jan93)
+	Note: as of DESQview 2.40, Quarterdeck's DEVICE.COM is able to install
+	  drivers into the device chain in the same manner as DVdevload;
+	  however, DEVICE uses eight times as much memory as DVdevload and
+	  has a serious interaction with 4DOS/NDOS that can lead to system
+	  crashes.
+
+RBspeed
+	Switch the CPU speed of an Intel Pentium motherboard using the
+	"Neptune" chipset.  Public Domain.
+	Current version: RBSPEED1 (v1.00 08sep94)
+
+SPTURBO
+	An integrated environment for Borland's Sprint word processor and
+	Turbo C, Turbo Pascal, Turbo Assembler, Turbo Debugger, and CDECL.
+	Knows which compiler to invoke based on the file's extension, and
+	can run MAKE for multi-file projects.
+        Current version: SPTURBO (v2.3 Aug 1,1989)
+	Note: There will be no further updates of this package.
+
+PURGEMSG
+	Delete or copy *.MSG files such that you only see those messages
+	from a Fidonet echomail area which interest you.
+	Current version: PURGEMSG (v1.00, 04aug91)
+
+--------------
+Authentication
+--------------
+
+Beginning 1/1/91, all packages are distributed in PKZIP archives with
+authenticity verification (v1.1 before 4/1/93, v2.0 after).  Please
+redistribute only the original archives to preserve the authenticity
+information.  If you receive an archive dated after 1/1/91 which fails
+the authenticity check, you should treat it with caution.  If you
+receive an archive which passes the PKZIP check but displays an
+authenticity code other than NWS235, then the archive has been
+deliberately tampered with and should be deleted IMMEDIATELY.
+
+Beginning 9/24/95, all packages additionally include detached PGP
+signatures in an enclosed archive named PGP-SIGS.ZIP.  My PGP keys
+are available from http://pobox.com/~ralf/ralf.asc or
+ftp://ftp.cs.cmu.edu/afs/cs/user/ralf/pub/WWW/ralf.asc

+This is the fifth of six archives containing the x/86MS-DOS Interrupt List,
+Release 61.
+
+This archive contains utility programs and viewers for the interrupt
+list.  Most of these programs have been contributed by others; if you
+have problems with a contributed program, please contact the author of
+the program with which you experienced difficulties.
+
+The DOS viewers Interrupt Helper, Interrupt Summary, and IVIEW are
+offered in this archive, as is the Windows viewer ILINA.  Interrupt
+Summary is designed to be keystroke-compatible with INTERVUE (which is
+no longer included), while offering additional functionality.  IVIEW is
+designed to conserve disk space by not requiring any additional index
+files and by itself being as compact as possible (under 2K!).
+
+In addition, the source code for COMBINE, INTPRINT, INT.COM, and the
+Epsilon extension code I use while editing the list are included in
+this archive.

+This is the sixth of six archives containing the x86/MS-DOS Interrupt List,
+Release 61.
+
+This archive contains programs to convert the MS-DOS interrupt list
+into hypertext databases for a number of popular hypertext help
+systems.  These programs have been contributed by others; I have not
+tested most of them personally because I do not own the help systems
+for which they produce databases.  If you have problems, please contact
+the author of the program with which you experienced difficulties.
+Some of these programs predate, and will thus not take advantage of,
+recent enhancements to the list's format.  MOST OF THESE CONVERSION
+UTILITIES ARE NOT STAND-ALONE PRODUCTS!  You must have the appropriate
+help system compiler to create an actual hypertext database which can
+be read by the help system; these are not included because they are
+commercial products, usually distributed together with the hypertext
+viewer.
+
+Not included here because it is rather large and is distributed
+separately by the author, is IL2HDK by Ron Loewy, a conversion program
+to put the interrupt list into Help Development Kit format, from which
+it can be converted into about a dozen different formats, including
+WinHelp, QuickHelp, Borland THELP, OS/2 IPF, POPHELP, and DESQview/X
+help. At the time of this writing, the current freeware version was 3.5
+(IL2HDK35), with v4.3 included in the commercial version of HLPDK
+(see http://www.hyperact.com/hact8.html).
+
+[NOTE: due to the change in table numbering introduced with Release 59,
+some or all of the following programs may fail to properly cross-reference
+tables.]
+
+
+Files in this archive:
+	README.6
+	HINTSRCH.ZIP	full-text search DLL
+	IL2ME102.ZIP	convert list into Multi-Edit help database
+	INT2RTF.ZIP	Slava Gostrenko's converter

+As usual, I still have a queue of unprocessed submissions....  If
+you've sent in any contributions which don't appear in this release but
+which I've acknowledged, they are still on my queue and will appear in
+the future.
+
+Still on the queue: more OpenDOS info, the rest of the TI Professional
+info, lots of chipset info (see NEEDHELP.TXT), ....
+
+
+UPCOMING CHANGES
+================
+
+The individual sections of the list will be larger in future releases
+so that there are fewer parts.  I'm planning on 720K per section unless
+there are strong objections.
+
+
+WHAT'S NEW
+==========
+
+INTER61
+-------
+New files:
+	FAQ.LST		start of an FAQ -- submissions welcome!
+
+updated files:
+	OPCODES.LST
+
+new info:
+	over 400k of additions, including: AHA-154x commands, ATASPI,
+	more MSRs (including AMD Athlon), lots of DR-DOS/OpenDOS/PTS-DOS/S-DOS
+	info (with more still to be added), AMIGATSR, MULTIJOY, USB4DOS,
+	VXDLDR, etc.
+
+Other changes:
+	INTERxxF and INTERxxG have been merged.
+
+Note:	I have deliberately omitted the usual renumbering of tables because
+	I still have lots of pending updates referencing tables using the
+	numbering from INTER60 (and there are no doubt some dangling
+	cross-references due to incomplete updating).  As a result, many
+	table numbers will be out of order.
+
+
+INTER60
+-------
+updated files:
+	OPCODES.LST
+
+updated programs:
+	INT2WHLP can now handle the new five-character table numbers
+
+new info:
+	Econet, VESA VBE/AF, Matrox VESA-OEM functions, more Soft-ICE backdoor
+	commands, XBIOS, EZ-Drive, Adaptec AIC-7xxx and AHA-152x ports,
+	GEM/ViewMAX, WinTel API, TrLit API, VHRBIOS.SYS, Philips SAA7110(A),
+	Intel 82595FX
+
+
+INTER59
+-------
+format changes:
+	all table numbers are now five characters in length, and just in time,
+	too: PORTS.LST now has 1014 tables....
+
+updated files:
+	OPCODES.LST
+
+new info:
+	chipsets: Intel 440BX/EX/LX, Intel 82371MX, OPTi "Vendetta", OPTi
+	  82C493/82C382, Via VT82C496G "486SXWB", Via VT82C570M "Apollo Master"
