I have set up my SCSI2SD with SCSI ID 6 (needed for the IIGS to recognize it, apparently) and a 30MB drive. Here are my results.


When I load Copy II Plus, it recognizes the drive. I can format it from there. There isn't an option to initialize it. I am not entirely sure what that actually means anyhow.


From Copy II Plus, I can also copy the contents of my System 6.0.1 disk onto it (although there is an error at some point) and it becomes bootable (almost), but then says that I need a SCSI driver on it in order to boot. How it begins to boot in the first place without the SCSI driver in place is beyond me.


If I put in the System 6.0.1 drive and boot it up (I have to manually set startup slot to 5 in this case), there is no hard drive icon on the desktop. When I pop in the system tools disk and run advanced disk utility, I can't see the hard drive anywhere no matter how many times I click the "disk" button.


I just can't figure out how to get System 6.0.1 to recognize the disk. It seems the IIGS itself is recognizing it just fine.


Does anyone have any recommendations?

What SCSI controller are you using with the SCSI2SD?

So I realized that the GSOS system disk does not contain a SCSI driver on it, but the System Tools 1 disk does. Unfortunately the System Tools 1 disk is not bootable, and there is not enough room on the system disk to just copy the driver over. I have tried to create a kind of "frankenstein" disk from the two with no success.


According to this page I am supposed to load up a system disk with SCSI support. How am I to do this??

Boot to the GS/OS installer (Disk 1), it will give you the option to install the OS with the SCSI driver.


Note: Unlike Macs, the Apple IIgs doesn't require a driver partition.

I figured it out. I had to use a SCSI utilities disk (Chinook) in order to properly partition the hard drive. Apparently doing it from my LC III was the wrong thing to do, and Copy II Plus didn't cut it either. Now the installer recognizes my drive just fine.
