High Speed SCSI and ProDOS

["Phil Abel" <ttsh35a@removethisfornospam.prodigy.net>]

"Just" upgraded from a Rev C to a HS SCSI card.  While GS/OS recognizes all
my drives just fine, I can not get ProDOS 8 to recognize any of them.  When
I boot the SCSI slot directly I get a "SCSI BOOT ERROR".  I don't have any
SCSI ID conflicts or anything.  I tried with DMA on and off and it didn't
change anything.  My other cards are a TWGS, GS Ram 4 w 4MB, and SuperSonic.
I seem to recall reading somewhere that the HS SCSI won't read a ProDOS
drive if you have multiple partitions?  Is this the case?  All the drives I
tested had 2 or more partitions.  If this is indeed teh case, what if I set
up a drive with 1 Prodos partition and 1 or more HFS partitions-- will I be
able to boot from ProDOS then?
