[comp.sys.ibm.pc.hardware] Old system - Help!

stanley@phoenix.com (John Stanley) (12/29/90)

   I have just gotten a Xerox 16/8 Professional Computer. This is a
system with both a Z80 and an 8086, which can run both at the same time.
Spiffy. 

   It comes with CP/M and MS-DOS. There are both an 8" floppy, and an 8"
"rigid" disk. I had no problem loading the CP/M on the hard drive. I
have no problem running MS-DOS from the floppy. 

   Unfortunately, the CP/M system will not read the main MS-DOS floppy,
and MS-DOS cannot write to the hard disk. There is no information in the
manuals I have that says how to load MS-DOS onto the hard drive. 

   Please. Can anyone mail me the secret incantation that will allow me
to put the MS-DOS onto the hard drive? I can get the MS-LOAD program
onto it, and make it run that on boot, but it complains about Bad
Command Interpreter. What is the missing step? 

   And, second question. The 8" is a Shugart 805. I have a sneaky awful
suspicion that I cannot just replace this with a generic 5.25" drive. Am
I right?

   Why bother with this system, you say? It is a gift to a charitable
organization. I would like to get it to a level where it can run 1-2-3.
