So you're telling me to zap the PRAM. Is this a wild guess, or a sure thing?
Anthony --
A PRAM-zap is the standard first step for solving "weird" Macintosh
problems. If you are in a situation that precludes proper operation
after a PRAM-zap then something is seriously wrong with the system. I
cannot see why any properly configured hard disk with a properly
functioning driver should not be able to boot after a PRAM-zap -- the
zap only affects certain low-level constants that are held in
battery-buffered memory. I do not think that any of them could affect
a SCSI card, unless some _very_ profound changes in the Apple
hardware/System-software paradigm have happened in the recent past.
If, instead of a PRAM-zap, you are referring to a PMU reset (where
you open the case and press the PMU button), it might affect a SCSI
card, but I don't see how.
I found, once the system was installed, that a QuickSilver Mac
cannot boot from a drive connected to a 29160. So after a ton of
tech-time, Adaptec walked me through an Open Firmware
reconfiguration that allowed the QS Mac to recognize a system folder
on the 29160/UltraStar.
Updated drivers for the 29160 and OS X were released on the Adaptec
website 12/18/02:

If they are making a user hack Open Firmware to get a drive attached
to their card to work then both their advice and their products are
highly suspect.
As a long-time Adaptec user who has watched them seriously drop the
ball with OS X: I will stay away from their products until they again
prove themselves.
What I would personally do:
Pull all Adaptec cards and see how the system performs. If all is
fine install an Adaptec card and see if there are problems. If there
are do a net search (especially on MacFixIt.com) to see if it is a
known problem. Download the latest drivers and firmware updates from
Adaptec. Try again. Prepare to be disappointed.
My advice on recovering from disk problems with OS X:
1) Back up everything (if possible)
2) Boot in single-user mode (command-option-s on restart)
3) Type fsck -y <return>
4) Type 'reboot'
5) Repeat 2 through 4 until no problems are found.
6) Zap PRAM
&) Repeat steps 2 through 4 until no problems are found.
7) Run DiskWarrior on all disks.
8) Repair permissions with Disk First Aid
Good luck,
