You're absolutely right. Here is hopefully a better description. I have a 1 GB disk defined as LUN 0 and named FS3: on my 16 GB SD card in my SCSI2HD connected to a GVP HC+8 SCSI contyroller. There's also a 2 GB hard disk and a CD-ROM on the same SCSI daisy chain.
Originally, I booted 3.1 from floppy and installed 3.1 on FS3:. That worked fine. If I just powered up the machine, it booted directly to OS 3.1 on FS3:. Then I reloaded my backup of the original FS3: hard drive from a USB stick onto the new SCSI2SD FS3: by saying "copy <usb-name> FS3: all". Took about two hours.
Now when I try to boot from the SCSI2SD, the disk activity LED flashes around for a few seconds as usual but then all activity stops and I see nothing but a light gray screen. If I try to reboot using CTL-A-A, I get more disk activity and then the red error box with "Software failure. Press left mouse button to continue. Error: 0000 0008 Task: 00212DA0". At this point I have to power-cycle the machine to even be able to boot from my 3.1 floppy. That works, and an FS3: drawer icon appears on the workbench screen and I can access all the files there.
HDToolBox said there are "no drives in system". The window for the drives was empty and all the buttons below were grayed out except for Help and Exit. So I changed scsi.device to gvpscsi.device in the icon's info. Now it shows the drives on the SCSI2HD. But how do I tell if it thinks they're bootable?
If I try to boot FS3: using the "boot with no startup-sequence" option from the preboot diagnostic screen, it just goes to the ROM OS screen.
One other possibly relevant point - the USB backup was a 3.9 OS.
