The solution is a bios upgrade from Tyan. They promptly sent us new chips, but it is downloadable with a utiltity to flash the eproms, however we were not successful in this endeavor. I emailed Tyan support a couple of times and never received a response, but since they had sent us new eproms, I didn't have the time to pursue the flash method. The new version we have shows "Tyan Thunder 2 V1.16" on the boot up screen, so the chances are, if yours isn't at least this rev level, it doesn't save the scsi settings when you tell it to and think it is actually working...
