From: jmy@neural.hampshire.edu (Jason Yanowitz) Subject: [Q] Pt.2 of well-written FDomain SCSI question <READ ME, PLEASE> Date: 30 Mar 1993 00:28:39 GMT
*AARGH* The SCSI saga continues...
In our last episode, our fearless hero posted about his difficulties
getting his Future Domain TMC-840 SCSI card to be recognized by Linux.
His post was a work of art (in-depth, specific, complete). If people
who think they can help with this need it, please email me for a copy.
Anyways, the universal response was "You need to have the card on IRQ 5."
Our fearless hero was undaunted. "Okay," he thought, "I'll just call
the company and find out what the jumpers mean." (BTW, I still don't
know how to tell what IRQ the card is using software. If you know how,
please tell me.) So, Future Domain told me the following:
W1 and W2 determine what address the card uses. I've got both closed,
so it's at DE00:0
W3 and W4 determine the IRQ. If I close W3, it's IRQ3. If I close
W4, it's IRQ5.
W6 and W7 determine the timeout delay. W6 closed causes a short delay,
W7, a long delay.
Obviously, I've closed W4 and also have done W7 (actually, I've tried
all combinations, to no avail).
Now by adding the rom signature:
FUTURE DOMAIN CORP. (C) 1986-1989 V5.0C2/14/89
(along with the 5, 46, and something else I'm not remembering but
I swear it's right. The signature does start at offset 5).
to seagate.c in the appropriate place, I get 1 SCSI host detected on
boot-up. Alas, 0 SCSI disks. No matter what combination of jumpers
I go with, I get 0 SCSI disks. (In case it's unclear, this is the
message Linux presents during boot-up).
I believe the disk has SCSI ID 0 b/c I get this message right after
my POST tests:
[Future domain SCSI, blah blah blah]
SCSI 0 LUN 0 quantum blah blah blah
then of course, the AMI bios status screen and then the kernel
starts loading...
FWIW:
I have a Quantum 80s HD (it's on the compatibility list).
and I've taken my Gravis Ultrasound out of my computer (just in case).
386-40DX w/ 20 MEGS ram. (shadowing disabled, 64k cache enabled)
ATI VGA Wonder+ 512k
stuff on COM1,2,4 (mouse, modem, sytek box, respectively). I've tried
taking them out, too...what the hell, I figured.
I gave all the configuration stuff I did with the kernel last time, and
no one had any criticism (except I was needlessly including the FD16XX
drivers, which I've since ceased including).
So, I've done everything I'm supposed to. I'm like Marvin
Gaye; What's going on?
*PLEASE* *PLEASE* *PLEASE* help!!!! I'm desperate to start running
Linux, and after 20+ hours of trying to configure this stupid SCSI
card, I'm reaching new states of desperation.
Jason "I hate SCSI" Yanowitz
ps: and another thing Norton's SysInfo tells me I'm only getting 500K
thruput when the drive can do 2M....is this cuz I have a crappy 8-bit
SCSI card. well, that's not really as important to me as getting Linux
to see my SCSI drive...
