Yes should work, though you may run into some problems with the BIOS not handling well the 1.44M FDC 😀

The IDE port won't work, obviously, but that doesn't really matter.

XT-IDE supports IDE with a 16-bit controller card in a XT. Works perfectly.

"- 16-bit ISA IDE in 8-bit mode Allows to use 16-bit IDE controllers on XT systems. This will require drive that supports 8-bit transfers (CF card and Microdrives all support 8-bit mode)."

Isn't the IDE header connected on the 16 bit bus (the shorter finger), which is disconnected in a 8 bit slot ?

true
the controller has to be an 8 bit card with matching bios.

I have 16 bit mfm cards that don't even have a bios.
none of the 16 bit ide/floppy cards I have has a bios.
They relied on the 286 bios

Yes, indeed. But with the XT-IDE-Bios only 8 bits are used. No need to get a 8-bit controller for a XT.

You have some spare ROM-sockets in your board- Put a XT-IDE in it and try 😉
