Uhhh I made my CP/M bios at home build computer with Z80 
CP/M (80) was developed for 8080 CPU and can only 64k.
CP/M86 of later date was running at 8086 and could indeed 640 on XT.
But it was not the CP/M as original designed and I believe also less
success full after all.

I had a bit overkill in 1980 with mapping of 16k segments out a range of 1000KByte.
Calling from TRS80 mode the CP/M system and back starting a second TRS80.
Not dual boot but dual run. :)
The good old days, snif.
