Roy:
Creating a new CBIOS is easy using modern tools. Assuming I can get
the first part done (floppy access on a modern PeeCee), my thought would be
to use 22NICE (the CP/M emulator), DDT and SYSGEN to do it.
I have a tool from Sydex to test the SD capability of a modern
PeeCee controller. If this passes, then I'm OK. The 22DISK manual mentions
that you can take an XT controller and modify it with an inverter to handle
FM disks.

was wondering the following. What if I setup an old PC
with a 5.25" drive
and use 22DISK to prepare a disk and move CP/M 2.2 .COM files to it from
the PeeCee. Then, I would have to figure out how to get the cold-start
loader onto the disk.
Does this sound like a viable scenario?
Writing the system tracks is definitely going to be the hard part, all
right.
Because you need that to include a BIOS that's specific to your hardware.
I'm in the same spot with regard to my BigBoard II, which I can boot a
Xerox
SSSD floppy on but then I only get SSSD support, even though the hardware
and the drives support DSDD.
If you figure out how to do this I'd sure like to hear about it.
