Slightly OT: XT-IDE

[Ali Fahimi M.D.]

Hello All,

I've been trying to help a friend of mine get his XT-IDE (DP ver 2 board) up
and running to boot a HDD in an IBM 8525. It is a bit difficult since he is
across the country but we have made progress. However, we still cannot get
the system to boot.

The card is recognized by the system, the boot menu comes up. At first we
could not get it to find a HDD. However, after a bunch of trial error we
were able to get the drive to be recognized. We booted w/ a DOS 6.22 disk,
ran fdisk /mbr, and everything seems to have completed but after reboot the
HDD will not format. Checking with fdisk shown no partition info at all.

The XT-IDE is the only card in the system, booting from floppies is fine
with no issues. We also have gotten a 1h error at times. Finally, to rule
out the HDD as an issue we tried to boot using the serial connection. The
card is seen by the server but when we attempt to boot again we get a 1h
error.

Config info as follows:

At this point I am stumped. Any help is appreciated. Thanks.
