have flex get called with the -I (interactive) option.

True. But it's not real workable as an easy general solution -

compared to installing filesystems on an Amiga, for example. Or even

in Linux, where you do have to compile things.

I mean that Microsoft won't support it. Microsoft has been known to

That's obviously the case. It seems the state of the art has managed

to improve a bit since I last really paid attention to the DOS world
|

(which wasn't all that long ago, before everybody jumps down my throat.)

Evidently. Isn't it amazing how much easier it when people explain

So when is the ext2fs for DOS going to be ready? :-]

You could presumably put an AmigaDOS filesystem on a physically

I thought that I'd mentioned that at one time someone was working on a

Minix filesystem for AmigaDOS. I'll have to ask the author if he's

Well what do you do then if the kernel suddenly goes bonkers one day,

and clobbers you /usr partition or something awful like that?!
|

Commerical un*xes have sanity checks, etc, why shouldn't Linux? Plus, if

you have a very intermittent problem, the debug stuff might make it

possible to find out what it is, else you'll never know. You'd have to

recompile with debugging after the fact and wait for it to happen again.

That might be an uncomfortable wait for those with mission-critical or

security related problems.

I've been using Linux (Slackware 1.1.2 0.99pl15 plus lots of sources)

I think Patrick has already done what you propose, with the recent
|
||||
Slackware 1.1.2 UMSDOS disk set. By using the UMSDOS Boot/Root disk combo,
|
||||
as well as a couple of other UMSDOS disks, you can install the Linux Slackware
|
||||
distibution (as much or as little as you like of it) onto an MS-DOS formatted
|
||||
disk.
|
||||
|
||||
I believe that he requires you to have 8MB or RAM to install with UMSDOS,
|
||||
because if your hard disk is formatted for DOS, odds are you are not going to
|
||||
be able to create a swap partition for the install process to use.
|
||||
|
||||
I also think that Patrick's notes on Slackware 1.1.2 state that the smallest
|
||||
UMSDOS installation (UMSDOS and A diskette series) is around 12MB of hard
|
||||
disk space.

Linux USED TO handle 127.x.x.x right for all values of x.
|

Now all 127.x.x.x address other than 127.0.0.1 seem to try to send out
|

the default route.

This is bad, can we bring back the old behavior (thus not violating the RFC's

It was nice, when I could boast Linux networking was the only implementation

Well, if there was #ifdef's in there, it would be the USER's choice to run
|
||||
witht the debugging code or not...If a user thinks he may have a problem
|
||||
or is paranoid about not having the debugging code in the kernel, then they
|
||||
can leave it running. If you want to save memory and increase performance,
|
||||
then the user can take the risk of #undef'ing the debug code...

|

Since I wrote this, I feel the need to defend what I did. There is a
|
||||
basic problem that a cdrom has a sector size of 2048 bytes, and the default
|
||||
linux buffer size is 1024 bytes. Before we had the ability to use blocks !=
|
||||
1024 bytes, it was sometimes required that we splice together the two halves of
|
||||
a 2048 byte sector in order to make sense of the directory entries which span
|
||||
the boundary. If instead we tried to use a structure that was split over
|
||||
|
||||
Note that now we do have the ability to use blocks != 1024 bytes (try
|
||||
mount -t iso9660 -o block=2048 /dev/sr0 /mnt). This is still not perfect,
|
||||
however because ZMAGIC binaries have a 1024 byte header, and to be able to
|
||||
execute binaries directly from a cdrom you generally want to be able to mmap
|
||||
the file. Since the first page of the file resides at offset 1024 to
|
||||
1024+4096, this means that it would span the region from sector 0, offset 0x400
|
||||
to sector 2 offset 0x3ff. Unfortunately this screws up mmap somewhat because
|
||||
the buffer cache is not set up to split buffers across page boundaries. In
|
||||
less technnical terms you sacrifice demand loading and the sharing of pages
|
||||
between the buffer cache and process text pages by using ZMAGIC binaries from a
|
||||
cdrom mounted with a 2048 byte blocksize. One way around this is to simply use
|
||||
QMAGIC binaries, and if you are cutting a cdrom this would probably be a good
|
||||
thing to do. One of the reasons that I modified the kernel/linker/gdb was to
|
||||
support this.

No, I think that kfree is atomic, and until you call some other
|
||||
function that requests memory, you can technically still use the memory. It is
|

wrong, of course, and I forwarded these patches to Linus, but it does not
|

surprise me in the least that no one has encountered this.

Several people have said "Use bootlin" (mostly by mail.)
|
||||
|
||||
>>> I've tried the bootlin stuff referenced by the LILO documentation but
|
||||
>>> it doesn't work on any of the machines I've tried it on.
|
||||
|
||||
Is what I said in my initial post. In case it matters the only
|
||||
bootlin I can find is dated from early 1992, if there is a more recent
|
||||
version perhaps this solves my problems.
|
||||
|
||||
The problem with bootlin is that it assumes that not much has been
|
||||
loaded into the machine when it starts up and it doesn't seem to
|
||||
support modern kernels. The reason I suggested the strange order of
|
||||
loading:
|
||||
|
||||
> a. From a DOS executable load the kernel into some memory (may need
|
||||
> DOS network devices etc up)
|
||||
> b. Make BIOS calls needed by (1) to get parameters.
|
||||
> c. Disable interrupts, move myself to beyond 0x098000 (and jump there)
|
||||
> d. move kernel to where it wants to live including the first 2.5K at
|
||||
> 0x090000 the rest at 0x010000, copy parameters from (b)
|
||||
> e. Run the (2) startup code thus starting the kernel.
|
||||
|
||||
was so that the only calls needing the BIOS or DOS are before we stomp
|
||||
on the DOS/BIOS areas of memory. From the lack of positive responce
|
||||
that noone else needs this, so I'll go off into a corner and try it
|
||||
myself.

||||

At least one of the questioners had Amiga floppies, but no longer had

access to an Amiga. I use a Linux PC at work, and would prefer to

transfer stuff home to an Amiga without having to go through 8+3

be written, it would have (limited) uses.
|

|

(Someone did ask if minix or ext2 filesystems existed for AmigaDos
|
||||
(working in a similar way to CrossDos/MessyDos), but I didn't see an
|
||||
answer. It may be a better answer to transferring files LinuxPC -> Amiga.)

I'm trying to increase maximum number of processes for my pl14 kernel,
|
||||
with no luck.
|
||||
|
||||
I found constants called NR_TASKS in tasks.h, and the derived constant
|
||||
MAX_TASKS_PER_USER in fork.c. Increasing NR_TASKS and rebuilding the
|
||||
kernel does nothing for me. Fork still fails at about 40 total processes.
|
||||
|
||||
I've put prink's in all branches of fork.c to try to see what's
|
||||
happening, but I don't get any messages, so I assume you need to run a
|
||||
daemon (syslogd?) to see them.
|
||||
|
||||
Any pointers?

I'm not convinced that it's right for 127.0.0.2 to be regarded as
|
||||
loopback. But if you want it, you can get it. It's all a matter of
|
||||
how you set up routing when you turn on loopback. I just enabled lo
|
||||
(which I normally don't have running) using
|
||||
|
||||
ifconfig lo 127.0.0.1
|
||||
route -n add 127.0.0.0 dev lo
|
||||
|
||||
Ping works equally well to 127.0.0.1 or 127.0.0.200.

You could have saved yourself a week of time by reading the Makefile:
|
||||
# Set this to the lex you want to use, and if they lex uses a library.
|
||||
# linux will want LEXLIB set to nothing.
|
||||
|

LEX = lex
|

LEXLIB = -ll
|

I've also made a symlink from /usr/lib/libl.a to /usr/lib/libfl.a for
|

the future.

I've noticed the same problem when using term with tredir. If it closes
|
||||
unexpectedly, the connection won't close properly and hangs there in
|
||||
CLOSE_WAIT. I have to reboot to get the port back. This has also happened
|

when running a mud on port 4000 and telnetting to localhost from another
|
||||
console (I'm not on a network). What's the deal here?
