As one suggestion, you do not need to use the original IBM Setup disk. 
There are plenty of third-party MS-DOS utilties to do the AT Setup, and
I'm pretty certain some of them are more user friendly and include drive
topologies.

On this topic, I recently located an original IBM Monochrome monitor, so
for me it's now just a matter of pulling out the EGA Techref and
jumpering the IBM EGA card in my AT for EGA monochrome and plugging the
monitor and an original PC-AT 84 key keyboard in, and I can fire up the
AT I've been wanting to check out for over a year.
