SCSI Blues [Was: Re: AppleII Gs Problems]

[adam@aladdin.rado.uic.edu (Adam Powers)]

While on the subject of IIgs cards...

I recently acquired an 'as is' IIgs which I've been nursing back to health.
It's a "Woz" edition - I upgraded the ROM to version 01, and it now has 1280K
of RAM.  I can boot from floppy with GSOS 6, so the next logical step is to
add a hard drive...  Here's where I get stuck.  I pulled an Apple-branded
40 MB Quantum drive from a scuttled Mac and put it in an external case.
With the SCSI ID set to 6 and termination on, the drive showed up just fine
when connected to a Mac.  The GSOS installer couldn't find it.  I used the
Apple's HD SC Setup on the Mac to reformat and create ProDOS partitions on
the drive, but still no luck.

Any suggestions on whether this is a software or hardware problem
(i.e., am I missing something simple like installing a IIgs-specific driver)?
My card is labeled "CMS SCSI II" and I've tried it in a couple of slots.
There are many many jumpers on the card, and I don't know what they do.  
Here's the layout of the card:
"JP1" just below the ribbon cable - jumpered
"JP2" just above the ribbon cable - open
then there are six banks of eight jumpers each:
"D10" - #6 is jumpered, rest open
"SZ1" - all open
"PS1" - #4,5,6 and 8 jumpered
"PS2" - all open
"HID" - #1 jumpered
"SZ2" - #3,4 and 5 jumpered
Any suggestions/insights welcome!  Thanks.
