ALL linux distributions have no problem with big disks. *LILO* has
trouble with big disks. Several options:
1) Use a different boot manager.
2) Use loadlin.exe from Autoexec.bat somehow. It might even work from the
Start menu. (I don't use MS-Windows myself, so I have no experience with
this hack.)
3) Use Partition Magic to shrink MS-Window's C: partition to leave 5 meg
between it and cylinder 1024. Create an ext2 partition there, mount it
a /boot, but vmlinux-xxx there. Lilo becomes happy...
4) As 3, but make 64meg available mount as /, putting /usr, /var, /home,
etc. elsewhere.
5) Use a boot floppy.
There is a lilo variant / replacement that use the big disk BIOS calls,
but I think it only works for IDE disks. This would be under 1 above.
Since I only deal with pure Linux systems, I always opt for a 64 meg
root (/) partition at the beginning of the disk, regardless of size.
Lilo is always happy, since vmlinux & crew are always below the infamous
1024th cylinder...

Reply-To: [EMAIL PROTECTED]

Well, actually, I'm using ide-scsi, that is IDE SCSI Host emulation.
I have an AMDK6-2 at 450Mhz with a Creative 6424 (Ricoh) drive. As I
mentioned, 2.2.13 works day-n-night with no CDR problems BUT .14 and
15 have. After doing a little research I have noticed that there
have been a lot of "un-commented" changes to the
/usr/src/linux/drivers/scsi/ code. For instance ide-scsi.c is still
listed as V0.9 and the last "Changes" entry is dated July 4/99 but the
file itself is dated "modified April 2000" (I think, I've been
fiddling around trying to add debug messages to see where the problem
lies).
Any way I have downloaded a virgin copy of 2.2.15 (I have been
patching for some time now) and I will try a fresh compile from fresh
source. This is called "grasping at straws"! :-)
Also, I tried downloading the newest cdrecord (1.8.1) and that didn't
resolve it either.
Any other suggestions, comments, voodoo rituals that may work? :-)
Thanks for the response!

Of course you can always find out which program produced the
core dump by using the command
file core
The core dump is a memory image as you say. I've never tried
to look at one under Linux, but I did under SunOS. You can
probably get information about stack and register status, but
what good would that do you?

This switches desktops, not window managers, two different things. But

Subject: Configuring an *old* WD ISA EtherNet card...
Date: Tue, 09 May 2000 00:49:23 GMT
I have a box which I put in an old WD ISA EtherNet card (the price was
right -- $5.00), but I cannot seem to get a network connection. The card
has three network connectors: 10BaseT, AUI, and 10Base2 (thin coax). I
would like to use the thin coax, but I suspect that the NV RAM or EEPROM
on the board wants to use either the 10BaseT or AUI. Western Digital no
longer seems to even admit that they once make NICs. This machine does
not have any flavor of MS-DOS or MS-Windows installed. I'd like to know
if there exists a *linux* program that can diddle the NIC's on-board
config (NV RAM or EEPROM) to make the NIC use its 10Base2 (thin coax)
connector.
The card itself IS seen by the kernel:
Extracted from /var/log/messages:
May 8 20:29:44 smaug kernel: wd.c: Presently autoprobing (not recommended) for a
single card.
May 8 20:29:44 smaug kernel: wd.c:v1.10 9/23/94 Donald Becker ([EMAIL PROTECTED]

May 8 20:29:44 smaug kernel: eth0: WD80x3 at 0x300, 00 00 C0 EE BA 71 WD8013, IRQ 10,
shared memory at 0xcc000-0xcffff.
This is a RedHat 6.1 system: '486DX2-66, three ISA slots, 20meg of RAM
(an upgrade to 32meg is planned), a 4.1gig Seagate SCSI disk,
AHA-1540B, a Boca ATIO55 (2S1P), and the WD8013 NIC. The motherboard
has 2 serial, 1 parallel, floppy, IDE, and PS/2 mouse port, and built
in SVGA controller. I want to use this box as a headless print server
(for two printers -- the Boca 2S1P board has both serial ports
disabled, and the parallel port set to lpt2). It is old Dell Netplex
433/P system.

Hoo boy. Find some kid taking CS 101 and she'll tell you this:
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
int main(void)
{
int i;
srand(time(NULL));
printf("Static text|date %s|",asctime(time(NULL)));
for(i=0;i<70;i++)
printf("%d|",rand()%71);
putchar('\n');
return 0;
}
compile, run, call from cron... It'll spew its stuff to stdout, you can
of course redirect its output. The degree of randomness isn't all that
great when you use rand(), but something like lrand48() may not be
available everywhere (even though it seems to be on the 3 Linux boxes
around here.) You could also do this in Perl:
#!/usr/bin/perl -w
srand;
printf("Static text|%s|",scalar localtime());
for($i=0;$i<70;$i++){
printf("%d|",rand(70));

Sure, run how ever many you like. A typical Slackware setup runs
only 1 when using an XDM login; I changed it to keep 2. It has
no affect on network logins.
