Short list of differences between 1.7.0 and 1.7.1:
|
|
|
|
- The BIOS driver can now operate in 286 or 386 protected mode.
|
|
|
|
- Higher RS232 baud rates
|
|
|
|
- More robust ethernet driver that supports the WD8003, WD8013, NE1000,
|
|
NE2000, and SMC Elite Ultra.
|
|
|
|
- Interface to the Boot Monitor changed so that Minix can return to
|
|
it. Also support for a BIOS disk I/O call added. Minix 1.7.1 must
|
|
be booted by the new Monitor.
|
|
|
|
- New are the Mitsumi & Soundblaster drivers. Neither of these have been
|
|
tested very well after integration in 1.7.1.
|
|
|
|
Long list of differences between 1.7.0 and 1.7.1:
|
|
|
|
include/errno.h
|
|
ERROR changed into EGENERIC (symbol ERROR often used in user code,
|
|
although all E* symbols are reserved if <errno.h> is included.)
|
|
|
|
include/unistd.h
|
|
Rebooting codes for various ways of rebooting added.
|
|
|
|
include/minix/cdrom.h
|
|
For the Mitsumi CD-ROM driver.
|
|
|
|
include/minix/com.h
|
|
Changed task number definitions of optional tasks to
|
|
|
|
#define TASK (PREVIOUS_TASK - ENABLE_TASK)
|
|
|
|
This replaces the former #ifdef spaghetti. The ENABLE_XXX defines
|
|
must be exactly 0 or 1.
|
|
|
|
include/minix/config.h
|
|
Z_MAP_SLOTS upped to 32 to allow V2 file systems of up to 256 Mb.
|
|
ENABLE_XXX variables for Mitsumi CD-ROM and Soundblaster drivers
|
|
added.
|
|
|
|
include/minix/const.h
|
|
NR_IOREQS symbol introduced as the maximum size of a scattered
|
|
I/O vector. Vectors used to be NR_BUFS in size, which is a
|
|
potentionally large value.
|
|
|
|
NR_TASKS redefined as (10 + ENABLE_XXX + ENABLE_YYY + ...).
|
|
|
|
include/minix/sound.h
|
|
For the Soundblaster driver.
|
|
|
|
include/minix/syslib.h
|
|
Declarations for all the interface functions to the system task
|
|
added.
|
|
|
|
include/sgtty.h
|
|
Definitions for higher baud rates. (Some so high that they are
|
|
not likely to even work, but you can never know.) Untested!
|
|
|
|
include/sys/ioctl.h
|
|
Carloads of ioctl request codes added for font loading, CD-ROM,
|
|
and Soundblaster.
|
|
|
|
man
|
|
Various manpages updated, several new ones for new commands.
|
|
The boot(8) manpage contains several new or changed boot
|
|
parameters, and the TCP/IP configuration section is updated for
|
|
the new ethernet driver.
|
|
New manual pages: loadfont(0), isodir(1), isoinfo(1), isoread(1),
|
|
mixer(1), playwave(1), cdplay(1), isoread(1), recwave(1),
|
|
screendump(8).
|
|
|
|
src/boot/boot.c
|
|
Boot device name in boot monitor prompt.
|
|
|
|
src/boot/boothead.s
|
|
Allow Minix to return to the monitor. This means that Minix is
|
|
just a subprocess to the monitor. The monitor either reboots Minix
|
|
(this is very fast) or shows the monitor prompt (halt).
|
|
|
|
Offer a support function for Minix-386 to make a BIOS int 13 call
|
|
for bios_wini.
|
|
|
|
src/boot/edparams.c
|
|
Don't edit boot parameters unless there is a genuine Minix
|
|
bootstrap on the device. Exit command to exit to Minix.
|
|
|
|
src/boot/extboot.s
|
|
Bootstrap that boots Minix in an logical (extended) partition.
|
|
For if you really, really, need to have Minix in logical
|
|
partition. (For the brave and foolish.)
|
|
|
|
src/boot/installboot.c
|
|
Support for extboot.s.
|
|
|
|
src/boot/masterboot.s
|
|
Stupid bug fixed in the "BOOT B:" trick. (Boot the other floppy
|
|
if floppy 0 contains masterboot.)
|
|
|
|
src/commands/aal/archiver.c
|
|
Use a temp file in /usr/tmp for /tmp may not be big enough to
|
|
contain a copy of the library.
|
|
|
|
src/commands/ellec.c
|
|
Bug fixed to make 'ellec -Profile' work.
|
|
|
|
src/commands/i386/asmconv
|
|
Translation of complex jmp and call targets from ACK to NCC or GNU
|
|
fixed. Proper translation of CBW, CDQ, CWD, and CWDE from BAS to
|
|
ACK.
|
|
|
|
src/commands/i86/cc.c
|
|
Give better advise than using chmem.
|
|
|
|
src/commands/ibm
|
|
New commands: cdplay, loadfont, mixer, playwave, recwave.
|
|
Moved in from commands/simple: loadkeys, screendump, term.
|
|
|
|
src/commands/ibm/fdisk.c
|
|
Fixed master bootstrap included.
|
|
|
|
src/commands/ibm/part.c
|
|
User interface changed to make it tad more user friendly. Also
|
|
fixed master bootstrap included.
|
|
|
|
src/commands/ibm/readclock.c
|
|
Don't complain if the machine is not an AT or PS/2.
|
|
|
|
src/commands/ibm/screendump.c
|
|
Mono or colour? Just look at BIOS variable 0x40:0x63 and you know.
|
|
|
|
src/commands/kermit
|
|
Higher baud rates. Untested!
|
|
|
|
src/commands/mined/mined1.c
|
|
Allow characters with bit 8 set. (KJB's idea of internationalization
|
|
is that all characters with bit 8 set are letters.)
|
|
|
|
src/commands/reboot/shutdown.c
|
|
New flags: -R: reboot with a hard reset (old style reboot),
|
|
-x "boot hd1": execute this monitor code on reboot.
|
|
|
|
src/commands/scripts/DESCRIBE.sh
|
|
src/commands/scripts/MAKEDEV.sh
|
|
Add knowledge of /dev/cd*, /dev/audio, and /dev/mixer.
|
|
|
|
src/commands/scripts/instdist.sh
|
|
Added more text to make it more expert hostile. Find out what our
|
|
root and usr devices are. If usr=fd0c then root is on fd0, etc.
|
|
|
|
src/commands/scripts/mkdist.sh
|
|
Make V1 file systems to save a few bytes.
|
|
|
|
src/commands/scripts/whatis.sh
|
|
Search expression fixed.
|
|
|
|
src/commands/simple
|
|
New command: isoread.
|
|
Obsolete or useless and thus removed: fix, getlf, gres, hyphenate.
|
|
Moved to commands/ibm: loadkeys, screendump, term.
|
|
|
|
src/commands/simple/dd.c
|
|
Added 'conv=silent' to suppress "records in/out" messages. This
|
|
option is unportable, but useful in Minix specific scripts.
|
|
|
|
src/commands/simple/file.c
|
|
Replaced by the Minix-386vm version for it understands more
|
|
executable types. (Old file didn't know Minix-386 binaries.)
|
|
|
|
src/commands/simple/in.rshd.c
|
|
Some port selection bug fixed. (Je ne parle pas TCP/IP.)
|
|
|
|
src/commands/simple/rarpd.c
|
|
Major overhaul. Checks if networks already configured, makes RARP
|
|
requests, slices bread, answers RARP if /etc/ethers exists.
|
|
|
|
src/commands/simple/rsh.c
|
|
Proper path to rlogin.
|
|
|
|
src/commands/simple/vol.c
|
|
Added knowledge of tape block sizes. Very useful now for compressed
|
|
backups to tape. New manual page.
|
|
|
|
src/fs/cache.c::rw_scattered()
|
|
Limit I/O vectors to NR_IOREQS blocks. NR_IOREQS = max(NR_BUFS, 64).
|
|
|
|
src/fs/const.h
|
|
FS_STACK_BYTES symbol removed. FS is now loaded with a normal
|
|
crtso.s instead of the special head.s. The stack size is set
|
|
with chmem. The stack is allocated by the boot monitor.
|
|
|
|
src/fs/file.h
|
|
Locking definitions moved to lock.h.
|
|
|
|
src/fs/glo.h
|
|
The fstack array removed.
|
|
|
|
src/fs/lock.[hc]
|
|
Locking code formerly in file.h and misc.c.
|
|
|
|
src/fs/misc.c
|
|
Locking code moved to lock.c.
|
|
|
|
src/fs/read.c
|
|
Bug with large pipe writes fixed. (Return count was wrong.)
|
|
|
|
The rw_user() function removed. All calls to rw_user() are
|
|
replaced by sys_copy() calls.
|
|
|
|
Read ahead limited to NR_IOREQS blocks.
|
|
|
|
src/fs/table.c
|
|
Device table cleaned up and CD-ROM, AUDIO, and MIXER devices
|
|
added.
|
|
|
|
src/fs/utility.c
|
|
The sys_xxx() functions moved to src/lib/syslib.
|
|
|
|
src/inet
|
|
Broadcast ethernet address properly recognized, and other little
|
|
fixes.
|
|
|
|
Stack array removed in favour of a stack created by the monitor.
|
|
|
|
src/kernel/aha_scsi.c
|
|
Deadly bug fixed in the CD-ROM reading code.
|
|
Drives larger than 1 Gb have a fake 255x63 geometry. (This was
|
|
already so in the 386vm driver. Stupid of me not to adapt this
|
|
one.)
|
|
Major overhaul to remove code that issues multiple commands to the
|
|
same target. Hardly made a performance difference, but complicated
|
|
the code leading to crashes on moon phase changes.
|
|
|
|
src/kernel/*_wini.c
|
|
Partititions is not speled that way.
|
|
|
|
src/kernel/bios_wini.c
|
|
Adapted to run in protected mode. (Both 286 and 386 protected mode!)
|
|
Max number of drives set to 4.
|
|
|
|
src/kernel/clock.c
|
|
Code added to reprogram the clock to the BIOS rate at Minix halt.
|
|
Tricks added to collect clock ticks that get lost when the BIOS
|
|
driver is active.
|
|
New millisecond timer primitives to aid in high speed polling of
|
|
I/O registers. Various drivers adapted to use them.
|
|
|
|
src/kernel/console.c
|
|
Don't blank the screen when switching to software scrolling. Don't
|
|
change the cursor shape. Code added to load a new font into the
|
|
VGA card. There are no fonts yet though.
|
|
|
|
src/kernel/dp8390.[hc]
|
|
New ethernet driver for cards based on the DP8390 chip.
|
|
|
|
src/kernel/driver.c
|
|
Several nop_xxx functions removed. Tasks are now completely
|
|
configured out of the kernel, they no longer run a dummy loop.
|
|
|
|
src/kernel/ether.[hc]
|
|
src/kernel/hw_conf.h
|
|
Old ethernet driver. Removed.
|
|
|
|
src/kernel/i8259.c
|
|
Reprogram the interrupt controllers only if in protected mode. In
|
|
real mode we use the normal BIOS interrupt vectors, and only
|
|
reprogram those that Minix needs.
|
|
|
|
src/kernel/keyboard.c
|
|
CTRL-ALT-DEL now halts instead of rebooting. (The monitor would
|
|
otherwise reboot Minix-386. This is usually not what the person
|
|
behind the console wants.)
|
|
|
|
Reboot code changed to return to the monitor for Minix-386. All
|
|
devices appropriately reprogrammed for the BIOS.
|
|
|
|
src/kernel/keymaps/spanish.src
|
|
Modified by Javier Garcia Martin (jawa@inf.deusto.es).
|
|
|
|
src/kernel/klib386.s
|
|
src/kernel/klib88.s
|
|
8086 bios13 code changed to enable all unused IRQ's and to
|
|
disable them afterward, so that bios_wini need not know the IRQ
|
|
of the disk. 286 bios13 allows bios_wini to operate in
|
|
protected mode. It steps back to real mode with a processor
|
|
shutdown, makes the BIOS call, and steps back up to protected
|
|
mode. The 386 version makes a call to a monitor function that
|
|
makes the call using 386 ways to step in and out of real mode.
|
|
Don't read this code if mentally unstable.
|
|
|
|
Port_read_byte() and port_write_byte() functions added that do
|
|
block port I/O in byte mode. (Needed for the NE1000 driver and
|
|
the Mitsumi CD-ROM driver.)
|
|
|
|
Protected mode initialization code cleaned up and calls to it
|
|
removed from C code.
|
|
|
|
Extended memory copy removed from klib88.s::phys_copy() for lack
|
|
of use.
|
|
|
|
src/kernel/main.c
|
|
Stack pointers of servers initialized to the top of their
|
|
address space where the monitor has made a stack.
|
|
|
|
Stack guard words for the tasks added. The system now panics
|
|
early if a tasks overruns its stack, instead of crashing in an
|
|
adjacent task.
|
|
|
|
Real mode vector initialization code removed. Minix now runs in
|
|
real mode with only minimum changes to BIOS parameters. All the
|
|
special case code for real mode is gone. One should be able to
|
|
make BIOS calls from user programs, but that's just an unfortunate
|
|
side-effect of the cleanup. (The BIOS disk driver is happy though.)
|
|
|
|
src/kernel/mcd.c
|
|
Mitsumi CD-ROM driver by Michel Prevenier (mrpreve@cs.vu.nl).
|
|
(Andy has these fun projects for his students. :-) )
|
|
|
|
src/kernel/memory.c
|
|
The RAM disk can no longer be placed in extended memory. Minix
|
|
should now be able to run in protected mode on any 286 or better,
|
|
so we can forget about "extended memory" being special.
|
|
|
|
src/kernel/mpx386.s
|
|
src/kernel/mpx88.s
|
|
Flags set to tell the monitor that stacks must be made for the
|
|
servers, and that Minix-386 would like to return on reboot or
|
|
halt. (Requires a new boot monitor, 1.7.0 monitor won't work.)
|
|
|
|
Cruft removed, protected mode initialization cleaned up.
|
|
Real mode int08-16 removed.
|
|
|
|
src/kernel/ne2000.[hc]
|
|
NE1000 and NE2000 code for the ethernet driver.
|
|
|
|
src/kernel/proc.c
|
|
Stack guard check in unready().
|
|
|
|
src/kernel/ps_wini.c
|
|
Writing enabled, driver otherwise nonfunctional. (See comments
|
|
in the file.)
|
|
|
|
src/kernel/rs2.s
|
|
src/kernel/rs232.c
|
|
RS232 hangup code contributed by Will Rose (cwr@cts.com).
|
|
Untested.
|
|
|
|
src/kernel/sb16.h
|
|
src/kernel/sb16_dsp.h
|
|
src/kernel/sb16_mixer.h
|
|
Soundblaster driver by Michel Prevenier (mrpreve@cs.vu.nl).
|
|
Hardly tested.
|
|
|
|
src/kernel/start.c
|
|
Several changes for the monitor return and BIOS calls. Call to
|
|
sel_wini_task() removed, as the BIOS driver is now even useable
|
|
in 286 protected mode. Simplyfied a bit w.r.t. real/protected
|
|
mode.
|
|
|
|
src/kernel/table.c
|
|
New definitions, stack sizes, etc. for the new drivers.
|
|
|
|
src/kernel/tty.c
|
|
New font change ioctl. RS232 hangup.
|
|
|
|
src/kernel/wdeth.[hc]
|
|
WD8003 and WD8013 parts of the ethernet driver.
|
|
|
|
src/kernel/wini.c
|
|
Panic if the selected hd driver doesn't exist instead of
|
|
silently failing.
|
|
Sel_wini_task() folded into winchester_task().
|
|
|
|
src/lib/*/rts/head.s
|
|
Removed.
|
|
|
|
src/lib/other/printk.c
|
|
Replaced by the Minix-386vm version that is somewhat smaller
|
|
and somewhat more ANSI C compliant.
|
|
|
|
src/lib/other/syslib.c
|
|
Moved to src/lib/syslib and split up.
|
|
|
|
src/lib/posix/_getcwd.c
|
|
Initialization bug fixed.
|
|
|
|
src/lib/syslib
|
|
All the sys_xxx() functions from other/syslib.c and the
|
|
utility.c files of MM and FS gathered here in separate files.
|
|
(Much like the system call stubs in the posix directory.) The
|
|
sys_copy() function is changed to look like the former
|
|
mem_copy() function of MM.
|
|
|
|
src/mm
|
|
SIGMASK changed to SIGPROCMASK in lower or upper case.
|
|
|
|
src/mm/alloc.c
|
|
src/mm/main.c
|
|
Get_mem() removed from main.c and built into alloc.c::mem_init().
|
|
|
|
src/mm/const.h
|
|
src/mm/glo.h
|
|
src/mm/table.c
|
|
Stack stuff removed.
|
|
|
|
src/mm/utility.c
|
|
Sys_xxx() functions moved to src/lib/syslib. All calls to
|
|
mem_copy replaced by sys_copy() calls. (Sys_copy has been
|
|
changed to have the same interface as old mem_copy, save a few
|
|
type changes.)
|
|
|
|
src/tools/init.c
|
|
Stack array removed. Abort signal (CTRL-ALT-DEL) now does a
|
|
halt.
|
|
|
|
src/tools/mkboot
|
|
Delay added to 'make hdtest' to make it visible that another
|
|
device is booted. The other device has its own set of boot
|
|
parameters! Test and floppy boot device changed into file
|
|
systems with copies of /dev and /minix. This script must now
|
|
be run as root from the start, 'su root' calls removed.
|
