Subject: moving/adding a hard drive

I have several dual-processor Z-100's with lots of RAM, dual 5 1/4"
and dual 8" floppy drives, and an S-100 bus.  It runs MS-DOS on its
16-bit engine and CP/M (which I rarely use) on its 8-bit engine.
Please forgive me for posting to this group, but absolutely NO ONE
answered my question on the Z100 group, so I'm hoping to find more
knowledgeable readers or hackers (in the good sense) here!

A dual-processor Vector 4 computer with 128K RAM, 10 Mb hard drive,
and 596 Kb hard-sectored floppy drive, running both CP/M and CP/M-86,
recently "fell into my lap".  It has a "modified" S-100 bus (its
cards do NOT have on-board voltage regulators).  It came with gobs
of software and works fine, but I have little use for yet another
computer. :-)  BUT IF I can move its disk driver board to one of my
Z-100's, that would be a positive step!  (I suppose I could always
try to sell the Vector, but I doubt it has enough resale value to
be worth advertising.  And just trashing it seems so wasteful.)

I have plenty of hardware "smarts" to add voltage regulators, change
I/O port addresses, etc., but I don't have the slightest idea how to
go about telling an operating system that I've added more drives.
I do have several disks of what appears to be BIOS/BDOS source code
for the 16-bit engine, and I have coded in assembly language for
many years.  It's almost embarrassing, considering my affiliation
and what I do for a living, but what I do NOT know is WHAT to do!
Can anyone please either tell me what to do or what to read (and
where to find it) so that I can learn what to do?
