R622 is the latest version
you need to load the ide_atl.bin to customize, this is the one that contains the boot menu (all "l" versions contain the extra stuff like the boot selector menu)

OK, so I did try that one, but it's like...12k? after I configure it, but the GW card only came with a 28C64 EEPROM which is too small for it (right?)...how did they get one of those on here? Is there a way to cut it down?

I got it! It was v1.1.5! (found here: https://code.google.com/archive/p/xtideuniver … lbios/downloads)

For some reason I can't get the 2.x.x versions to boot my setup but v1.1.5 works fine.

OK, now I've got the XTIDE card working with the latest v2 XUB.

Here's what I had to do:

1. Switch the jumpers on the card to high speed
2. Load the ide_at.bin firmware from the bin file
3. Configure the firmware as follows: 2 IDE controllers, first one set to 16 bit ISA, second one set to XTIDE rev 2, default boot 81; flash EEPROM
4. Disconnect the regular hard drive from the computer entirely, leave DOM attached to XTIDE card
5. Boot to a floppy DOS disk; check that C drive is there and corresponds to my DOM
6. Run fdisk /mbr, power off
7. Reattach the regular hard drive
8. Disable the hard drive in regular BIOS (to avoid having two "copies" of it)
9. It works!

For whatever reason I still can't boot from the regular IDE hard drive from XUB (it just reboots). To boot the regular drive I have re-enable it in BIOS, then hold Ctrl key after the BIOS boot to disable XUB and boot the regular drive. It kinda sucks because then I can't access the DOM in this mode.
