Removing Pin 28 from the CF-IDE adapter did not fix the issue..
It's just an idea, but if it's not a hardware issue, then maybe it's a software issue?
The ATA-2 specification (Fast ATA, Enhanced IDE) changed a lot of things back then.
It could be that the HDD routines in the BIOS have issues with that.

It's essentially IBM's AT Fixed Disk Adapter (WD1003 command set) and/or ATA (IDE, AT Bus) all they know.
That's why "HDD Auto Detection" is missing, also, it's a future ATA feature and not available on MFM/RLL controllers yet.
If BIOS is the issue, using XTIDE Universal BIOS could help here.
I had a similar issue in which it did, at least. It was a Schneider Tower AT with an outdated BIOS..
Whenever it was meant to boot DOS, it hung.
Anyway, this is just an idea, of course. 😅
