Justin T. Gibbs 33cb7dbb53 The aic78X0 cards have 0xff in all bytes of scratch ram after POST. If ... a BIOS was not installed, this will still be true by the time we probe the chip. We use this heuristic to determine if we should use the left over scratch ram target settings for controllers that don't have an SEEPROM. We also "snapshot" the host adapter SCSI id and whether ultra is enabled or not and use these values if a BIOS was installed. The card will act as if a BIOS was installed even if there wasn't one if you warm reboot, but since the scratch ram area is still valid in this case, its hardly worth the effort of writing a shutdown routing that clears out the scratch ram. This should make users of motherboard controllers happy.		1996-05-10 16:26:41 +00:00
