I have a slight problem with a Quantum Q250 that I yanked out of my
Mac II and put in a box for use with a Mac 512KE which has been upgraded
to a Plus using Dove's SCSI + memory board.

THe problem is that I cant convince the Q250 to boot before the other
hard disk attached, a (slow but reliable) HD20 from Apple. The Q250
comes factory set to address 0. I would like the HD40 (th Q250) to
boot first, and so need to set the address up higher than the HD20
(which is easily settable)

Question: What is the Pinout for the Q250's jumper block?

A better solution to this problem is to use the Startup Device CDEV.
It doesnt work, probably since it decides that my mac is not a plus...
(ok, so it isnt, really...)

so,

does anyone know if the CDEV does check machine type?
does anyone know where this check is in the binary?
I should be able to just set it down to the ident for a 512KE, no?

even if I do this, Will it work?

Respond thru Email or the newsgroup, either is fine.

Thanks. I'd like to straighten this out.
