I just got a IIgs from my Uncle that has a clone rev C scsi card. I got GS/OS 6.0.1 installed on an external HD (SCSI ID:1)
I'm trying to use an apple cd 300e (SCSI ID:5), but when I try to boot I get "Check startup disk."
According to google this drive should work for data, perhaps not audio, w/ GS/OS 6.0.1's cd driver. I have tried different SCSI IDs on both devices, different places in the chain, but the machine just won't boot with the CD on the SCSI chain. When I connect the CD drive to a Mac? It works just fine.
(I know it isn't a cable issue as I have used another HD in the chain and both devices work)
Any guru got a clue for me here?
Try to provide a termination power from the SCSI card with a diode modification described in the net if this is an original Apple SCSI card. How many of your SCSI devices in the chain are SCSI terminated? Could you show a picture of that clone SCSI card of yours.
OFF: I see no point in using CD with //GS, but who knows...
If the CD in the drive has correct format ( ISO9660 ) it works.
I´d rather more guess that it´s a problem of termination:
the test with both harddisks was working because one of the harddisks has deactivated termination.....
only the last unit in the daisychain is permitted to terminate the chain.
If termination is activated at both devices it will fail.
In case you can´t deactivate the termination at the CD Drive then use it as last device
and put the Harddisk upfront without termination.
If you still have problems then the format of the CD in the CD drive isn´t correct ( not ISO 9660 )
and the controller terminates action by timeout, because it can´t get the volume label of the
disc in correct time.....

With an original Apple II SCSI card this is wrong! With many devices the card works with one termination but with many it fails. You have to have both terminations - in the beginning and in the end of the SCSI cable! But the author of this topic is writing about a cloned SCSI card and I suspect it could be one of mines that have a proper host termination on board...
The hard drives I have used have term power enabled. I don't bielive this is possible on the Apple CD 300e unit.
I have tried both 1st and 2nd on the chain for the CD position with and without a passthrough terminator between devices and the card (with a terminator at the end as well...
Why use a CD with a IIgs? So I don't need two Macs between the IIgs and the net... Don't worry, on list for Uthernet card
HOWEVER, one of you fellows mentioned ISO9660. I have been burning HFS standard and using the driver off the GS/OS 6.0.1 (Off of Apple's Legacy Recovery Disc). I figured, "Hey it reads HFS partitions on the Hard drive, why not a CD?"
Maybe this is the silver bullet eh?
Just connect your SCSI hard drive(s) to a MAC (or PC with CiderPress software) and transfer whatever you want...Forget about the CDs! Could you show a picture of your SCSI card?
The IIgs will always try to boot off the SCSI device with the highest SCSI ID -- in this case, it was always trying to boot from your CD drive.

My good man, this may be it as the drives I have been working with are ID=0 (Fixed) and the other jumpered to ID=1. If so? I'll post back and I owe you a beer.
The card I have is identical to this...

Thats in fact a clone from georgel.
Until I see an actual photo I cannot be sure if it is mine or not. Here is an expert from the manual:
Heh, that's funny. I should try that sometimes.
