CS or master, CS is recommended, some HDs had a jumper for master or master
with slave present. It did matter.

I agree that CMOS reset may help, even that the CMOS battery 'may' need to
be replaced.

I have the QRCD for this model, which laid down the Windows '95 that came
with the PC. It was standard for this QRCD to put the setup partition on
the HD as well.

Going back a few years...... Remove all third party boards and additional
RAM, specifically, remove all non-Compaq RAM in this beast. You need to get
it as close to a factory configuration, and start from there....

Good luck,

Have you tried a CMOS reset--a tried and true fix for weirdness.....

The 4784 likely has an 8GB limit on the BIOS--are the other HDDs you've
been
trying to use larger than that?

Unless you have some systemboard controller failure CS or master should
make no
difference. And yes Setup should run from diskette no matter what the
condition of the HDD. That you can't run appropriate Setup programs hints
that
a CMOS reset might help....

From older support files I see that:

(SP2141 ) Personal Computer Setup (Version 1.51C Rev. A)

(SP10245) Personal Computer Diagnostics

The first being what one would run from the FDD, and the second used for
installing the Compaq Diagnostic, I believe...
