    Yes, You need to re-configure the XUB to boot from floppy first instead of the hard drive first and re-flash the eeprom,

    More serious problem now. Xt-ide and ide to CF adapter. The parallel cable started to smoldering. Seems its a wire in the centre of the cable. Ideas?

    Does your XTIDE card supply power on Pin 20, or is the CF adapter set to accept power on Pin 20 and the XTIDE card grounds that pin?

    It's a low-tech card no jumpers for power to pin20. Don't know about the cf tide card now jumpers on this card

    Is it this one?

    It says it supplies power on pin 20, there's no mention of a jumper. You may well be shorting something if your CF adapter doesn't support that.

    The schematic for that also shows power on Pin 20.

    Seriously, if it's starting to smoke that's not good. If you have a voltmeter you can check if you're getting 5v between pin 20 and pin 2, 22-30, or pin 40 on the IDE connector (or between pin 20 and any other ground in the computer) at the XTIDE end, and then you can check the the CF adapter to see if pin 20 is attached to a ground *or* if it's cross-connected to the 5v lead on the power plug; if pin 20 on the adapter is connected to the power plug I'd suggest seeing if it runs without the drive power plug attached.

    So you got this one https://www.lo-tech.co.uk/wiki/Lo-te...ter_revision_2 If pin 20 is fitted there should be power on that pin AFAIK
    OR
    Do you have this one https://www.lo-tech.co.uk/wiki/Lo-te...er_revision_2b C8 2.2uf needs to be fitted for power on pin 20
    Have you got the cable and CF adapter plugged in to the lo-tech ISA CF adapter correctly, If the cable burned, the CF adapter and CF card may now be toast.
