As an experiment, I've configured a BIOS that I think might make a compact flash card attached to a standard 16-bit IDE controller work in an XT class machine (i.e. an 8-bit ISA slot).
The BIOS image is 8K. To make this work, you'll need a 16-bit IDE controller card, somewhere to put the BIOS such as a EPROM on a NIC or a universal ROM board, and be able to disable the ROM BIOS on the IDE controller either through jumpers or by pulling the chip. The IDE controller must be using ports 1F0h and 3F0h.
Anyone interested in trying this?
