I'm looking into possibly hooking up a hard-drive to my Apple IIgs, but I have a question that I can't seem to find an answer for so perhaps you guys can enlighten me.
Regardless of the model Apple II, how do you specify whether or not you want to boot from the floppy or the hard-drive? Is there some literature on this?
Booting on power-up historically happens from high slot down to low slot
(i.e. from slot 7 down to slot 1) on all Apple machines; the IIgs has a
few extra tweaks you can make to change that a bit, but otherwise it's
high to low. Again, historically, most users and programs expect a high-capacity storage to be in slot 7, Disk II floppy drive(s) in slot
6, 3-1/2" disk in slot 5, mouse of mockingboard (sound) in slot 4,
80-column card in slot 3, serial comms in slot 2, and serial or parallel
comms (i.e. printer) in slot 1. Some deviations from that are less
harmful than others. :-)
A lot of this is history and unwritten convention, so that's probably
why you're not seeing a concrete "here's how to boot a thing."
If you're sitting at an Applesoft prompt, you can tell the computer to
boot a particular slot with the PR# immediate command. So PR#6 would
boot a floppy, and PR#7 would boot a hard drive.
