Today I had the day off and played a bit with an XT build I've been working on. I found an XTA (like ATA but for an XT) controller in a friend's dumpster, and even found a compatible drive in my garage.
Impressively, GLaBIOS (the open source XT BIOS) even lists the drive while it boots (I don't think there are many people at all that uses this configuration out there).
Here's a little video of it booting up. Next it will get FreeDOS, then I'll have an XT with a free BIOS and free OS!

Here's the XTA card, I couldn't find any reference on it on the Internet at all. My best guess is that it comes out of a Twinhead XT clone, since similar riser cards were found in later Twinheads with similar serial numbers. The jumpers can select at which address the ROM should be available. I happened to read a doc that mentioned that XTA disk roms should be loaded at C800. I wouldn't even thought of trying to adjust for that, and the original AMIBIOS doesn't display this address like GLaBIOS!
