As far as I am aware, it was only some models in the 3100 series
that used the shorter SCSI commands in the boot rom, which caused
issues with the boot disk. However, I'm not sure that exact thing
is the problem. You might very well have some display issues that
pop up in the boot monitor, even though the system will boot
perfectly fine from a larger disk.

On the older VS3100 systems (without large disk boot support), things
would boot fine on larger disks as long as the pieces of OS code that
are loaded in the early stages of the boot all happen to be located
early enough in the disk drive.  Since you can't guarantee that all
the needed files would be located early in the drive large disks were
"not bootable".

I fixed this by making the disks artificially smaller (by changing the
firmware tables on the disk).

But then I assume the disk appeared smaller also at later stages. Essentially you got yourself a smaller disk.

Or am I missing something?
