This problem is usually in the cable: this board has dual IDE
controllers, but you will often find that the devices are set as
master / slave on the primary controller with the secondary set up
without any devices on it. Move the CD-ROM to master on the
secondary controller and as often as not your problem will go away.
If this doesn't help re-post here and I will attempt some other
troubleshooting.

The documentation must have improved a lot since the last time I tried
it, then (version 2.2.6). I found it very confusing, but I managed to
build a kernel in the end. Even the "Complete FreeBSD" book didn't
help much.
I get a new (old) 486 later today, and I plan to try FreeBSD on that
one. I have some 3.0 CDs lying around.
It's all about what you're used to. I have installed Linux about a
dozen times now on different machines, compiled almost all kernels
since 1.1.x, so for me it has become routine. I'm completely new to
FreeBSD, so naturally I expect more problems from that OS.
For what it's worth, Solaris 7 is the OS I have had the least problems
in installing on an Intel-based computer.

There's a pretty old book entitled "Linux Configuration and
Installation" published by MIS:Press, (copyright 95, so things have
changed ever so slightly). It includes Slackware with it, so it (has
to) go into a detailed explanation of setting up X by manually writing
your XF86Config file. While I chose to use RH52's xf86config utility
to get a skeleton, having read this book came in very handy when I
decided to force X into using a higher resolution (it wanted to be
stubborn). I imagine there are more up to date books out there, but
this one is pretty complete. I dont know if you'll be able to find
it, but good luck! (i got my copy from my uncle)

Hello,
I have a problem with my Tayo Yunden cd-writer working under kernel
2.0.30 (Slackware 3.4) with an AHA-2940A Ultra (PCI):
when I try to write a cd with cdrecord 1.6 (cdrecord -v -eject speed=1
dev=4,0 /image/image.raw) I get the following error message :
TOC Type: 1 = CD-ROM
scsidev: '4,0'

Device type : Removable WORM
Version : 2
Response Format: 2

Identifikation : 'CD-WO EW-50 '

Device seems to be: Philips CDD-521.
Using driver for Philips CDD-521 (philips_cdd521).
Driver flags :

And few seconds later the following message is displayed:

SCSI bus is being reset for host 0 channel 0.
aic7xxx: (reset) target/channel 4/0
aic7xxx: (abort_reset) scb state 0x1, Command phase, SCSISIGI = 0x84

So, the problem seems to come from the scsi driver which generates
the timeout. This is strange because when I mount a cd on the T.Yunden
there is no problem, all is OK, I can read the cd.
REM: I installed the SuSe 5.3 distribution (kernel 2.0.35) and the
system
can't boot: the scsi driver generates timeout for the Tayo Yunden device
at boot time and crashes all the system (sorry, I have not the the boot
message for this configuration).

Subject: Tape Library Support
Date: 19 Mar 1999 08:06:32 GMT
Anyone know of support (API's, software suites, interface specifications...
anything) for large tape libraries under Linux?
Generally, the setup for these monsters is multiple SCSI tape drives and one
(or sometimes more) robotic arm to manipulate the tapes (stick 'em in the
drives, put 'em in the right slots, etc.). It's my understanding that the
arm is just another SCSI device.
The usual suspects (AMASS, ADSM, HPSS, etc.) cost thousands and only speak
to AIX, Solaris, and (gag) NT. Most vendors consider the SCSI commands for
the arm proprietary (making it damned difficult for us to roll our own
drivers).
Please, oh please, don't make me feed a linux cluster data from an NT box.
Any help, tips, related experience, or pointers would be greatly
appreciated.

Subject: Midi on CS423x w/2.0.36
Date: 19 Mar 1999 08:07:12 GMT
Reply-To: [EMAIL PROTECTED]
Does anyone have Midi working on a CS4232 family chip with kernel 2.0.36
(driver version 3.5.4) ? The notes in Readme.cards are a little
confusing. I take them to mean that Midi should work, but not to use
MPU401 mode.
When I enabled MPU401 in xconfig, I got an unbootable kernel, so that
seems right. Now, I have MPU401 off, and Midi on. One problem is that
the xconfig dialog expects me to supply an IRQ for the Midi interface,
but according to the Plug'n'Play utilities diskette for my PC (Dell
OptiPlex GXa), the Midi chip doesn't consume an IRQ, just an I/O
address. I put IRQ 9 which I know is free. (When I put IRQ 5, the same
as the sound driver, I got a conflict message at boot time.)
The sound system claims to be CS4236, but I suppose this is compatible
with CS4232.
The various Midi players are happy to start, it's just that nothing
comes out.

Could be a bad graphics board. Do you have access to another card to try and
see if you still have the same problem?
I may be wrong, it could be anything. I know on my brothers P-II his
AGP graphic card went bad and he started getting a "Missing or corrupted file
command.com" when he booted up. He switched to a new card and Windows boots
up fine. Can't remember what the AGP card was, been awhile. Been trying to
get him to use Linux. He's started to get really frustrated with Win 98, so
he may be ordering SUSE 6.0 like I did.

Not true. Later parallel port drives (with a cable marked

Here's my two cents.
OVer the past two years, I've tried Linux and Freebsd.
The first time Linux I noticed that I had to make floppies to install
linux. Freebsd booted from the cd.
I went throught the creating startup floppies and got Linux installed
and it wouldn't recognize my 3c905 card. Freebsd did.
I didn't try Linux again untill recently because I've motivated by the
number of people using it. (ten thousand french flies can't be wrong.)
So I installed it on a spare pc I had. First thing I try it to rebuild
the kernel. What I see is extremely poor and inaccurate documentation.
Sure I can work through this with enough posts to newsgroups and maybe
going on irc and being insulted by the teenagers in #linux but Freebsd
works correctly on everything I try.
For my money, (time is money) I'm scrapping Linux once again and going
back to Freebsd.
For anybody that thinks I'm crazy, read my post on "A kernel build
problem" and tell me where I made an error. Perhaps my error was reading
the f*ing manual and following the directions in the how-to's.
The directions for building a kernel in freebsd take about two
paragraphs and work flawlessly. I can execute the procedure in a few
minutes. I get the feeling with linux you have to join some linux cult
and get the inside information that is not covered in the docs.
I'm finding it hard to believe that linux has gotten so popular with
such poor documentation.

Most C-300A CPUs permanently work at 450MHz. Probably, your collegue

You can buy 68->50 pin converters in any better computer shop. They
are not cheap, though; expect a price of USD 20.-- and up.
However, keep in mind that having a scanner on the external port
of your SCSI card may yield unexpected results:
a) If you do have SCSi disks on the internal SCSI chain, then
you'll run into problems when scanning - typical SCSI scanners
don't support disconnect/reconnect and therefor do occupy the
SCSI bus during the scanning process;
b) if you already have two internal connectors of that SCSI card
in use, then you may not connect any device on the external port
at all , unless it is a U2W adapter card or a card with 2 SCSI
busses (e.g. AHA3940) ;
c) the scanner must be terminated with an additional external 50-pin
terminator plug on the seconary port of the scanner;
d) the internal devices' termination (including host adapter card)
has to be adjusted correctly.
