Tyan 1662D new Award BIOS bugs

Hi folks,
I have a Tyan 1662D motherboard with two PPro-180's. After
hearing that Award released a new BIOS through Tyan I went to the download
site and immediately grabbed a copy. [1] It's got support for the new
zip/ls120 MB floppy drives, UDMA33 HDD, and 'Oxygen' 3D video card
support, but - most importantly - it has support to boot off of CDROMs
(which my previous BIOS lacked, and is the feature I most wanted).

Unfortunately, it also seems buggy. My Symbios Logic SCSI
controller, with the NCR53C8XX driver, gets recognized after POST and
tests for devices on the SCSI chain. But, no matter what setting I use
for boot order (SCSI,C,A or C,CDROM,A or what_have_you) the computer
intermittantly refuses to attempt to boot off of the SCSI controller. So
I'll get a 'INSERT SYSTEM DISK AND PRESS ANY KEY' when it attempts to
boot, and if I press a key repeatedly after a while it will somehow catch
that the scsi controller wants to boot my primary disk and launch lilo.
This rarely happens on first try, however, and of course this never
happened with the previous BIOS. As you can guess, this makes rebooting
my computer unattended an impossability... I'm seriously considering
moving back to my previous BIOS if this continues unsolved.

So, I'm wondering if others are seeing the same symptoms, whether
you have an NCR based SCSI controller, or anything else. I'd like to
narrow down the problem to either _my_ SCSI controller, or see if it's a
general problem with the new BIOS. Finally, if you happen to have seen
this problem and have _SOLVED_ it... well, you know I'd just _love_ to
hear from you!

Thanks for your time,
J. Maynard Gelinas
