Is it possible to upgrade an XT-IDE controller to an AT-IDE controller to use in an 8086 computer? I have an WD FileCard 30MB but the drive is dead and I would like to upgrade it if possible to support an 44MB AT IDE drive that I have (WD93044-A).
The card I have looks something like this, only it has an additional header populated:
8088 and 8086 are XT computers. You need a 286 at least to be AT. I made up one of those Lo-tech 8-bit cf adaptors, it worked even in my 486.
Atari 2600, TI994a, Vic20, c64, ZX Spectrum 128, Amstrad CPC464, Atari 65XE, Commodore Plus/4, Amiga 500
PC's from XT 8088, 486, Pentium MMX, K6, Athlon, P3, P4, 775, to current Ryzen 5600x.

You're right, but I believe Stojke is asking if it is possible to upgrade 8-bit XT-IDE to support AT-IDE hard disks instead
of XT-IDE hard disk (which CF cards are often compatible with).

Cats love it, so it must be really awesome! 😁

Btw, I've found contradicting information regarding that machine.
Is your model an XT or an AT model ?

The computer I want to do this mod on is an Philips NMS9100. It also has an integrated IDE-XT interface.
I see, that's good. Unfortunately, I don't own any XT-IDE stuff so I can't say anything about the matter.
I do own an EPROM programmer, though. So if you need a custom BIOS chip for XT-IDE, just tell. 😀

I've wondered this as well. The WD ATA and XTIDE 8-bit controllers seem identical except for the IC installed at U5.
I’ve often wondered if you just ran the wires from the AT ide ribbon cable to the matched XT IDE wires on the motherboard leaving the upper 8 bits NC if you would just get a half capacity ide drive?
