[svlug] a highly improbable string of events with a scsi host adapter

[Barry Fujii]

Hello all,
	This is my first post to this mailing list, and a plea for help with my
redhat 5.1 box.

First a little background. The box is an intel 586 with an intel endeavour
motherboard.
It has a 3com 509 card on irq 3, 1 seagate 6.4 GB drive, a Western digital
1.4 gig drive and an ide cdrom drive
It had a completely functional redhat 5.1 installation on it and it booted
and ran wonderfully.

Then came the day we wanted to install a tape backup drive in it. We had an
old HP Colorado T4000s (8GB) laying around so I figured, what the hell.

I purchased a Mylex Flashpoint LT scsi host bus adapter (this is a tier1
supported scsi card according to redhats web pages.) I created a bootdisk
and rescuedisk before installing any hardware. I installed the adapter,
plugged in the tape drive with a scsi id of 0. The host bus adapter is on
irq 10, a non-conflicting setting. Upon rebooting the LILO barfed at "LIL".
I checked the scsi bios to determine if it was scanning the scsi chain and
disabled it (according to the manual) because I am not booting from the scsi
card. The LILO still hangs. I remove the tape drive from the chain. The LILO
still barfs. I boot from floppy and everything is peachy, the scsi card is
not detected however. I remove the scsi card and the machine boots normally
from the IDE drive. I reboot from the floppy with the scsi card installed
and rerun /sbin/lilo. Now the machine hangs at "LI" regardless if the scsi
card is in or out. It boots fine from the floppy, but is still not detected
by the kernel.

So the million dollar question is now this: How do I repair my LILO and get
the SCSI card to work?

Things that have been attempted:
	Yes, the card seems to be fine if I boot from a DOS floppy.
	Yes, the scsi chain is terminated with an active scsi terminator
Thanks in advance,
Barry
