Sorry--untrue.  (A reasonable guess based on limited info, but you
can easily verify that it's wrong by, for example, booting GS/OS
from slot 5 (as I sometimes do) and using disk devices in slots 6
and 7.)

GS/OS will not recognize an Apple SCSI card in any slot unless the
SCSI.DRIVER has been installed in the SYSTEM:DRIVERS directory.
However, ProDOS 8 (which replaces GS/OS automatically whenever you
launch BASIC.SYSTEM or any other SYS file) requires no special
drivers for the SCSI card or any other device whose ROM supports the
ProDOS interface.

In additon to the SCSI.DRIVER (install using the Installer), the ROM
on the Apple SCSI card needs to have a revision C ROM (see other
recent messages for the part number).  Note that at least one person
I know bought a SCSI card that *said* Rev C on the box, but it was
Rev B!  Don't believe everything you read on boxes....
