Subject: May I boot from drive B. Please? Pretty please?

[when in doubt, pip it!]

       When CP/M boots, it considers the drive that it booted from A:
and starts with with the A> prompt.  Can I corece it into believing
it booted from B:, and how?
       One may ask "why", and I haven't a complete answer.  I am
puzzling over how to handle a system with a SSDD and a DSDD drive.
Normally I boot from the SSDD, but if that boot is bad, I would want to
boot from the DSDD.  Unfortunately, the boot ROM looks only for device 0
so I have to change the drive addresses and will probably confuse
CP/M (watta you mean drive 0 is single sided? It was double sided when
I booted!).

       My solution for now is to logically define the double sided drive
as B: double sided and D: single sided.  This way, I can copy
A: (the single sided drive) to D: and use the disk in drive A:.
I just have to keep enough backups of the single sided system disk
to keep out of trouble.

       Thanks in advance.
