I recently picked up an XT IDE. It works fine for the most part, but when I tried to load BASIC samples from the original IBM DOS 1.1 floppy(I was booting from it), the system hung up, only showing a blinking cursor. When I have removed the card, everything was working. How can I fix it?

    If the EPROM is socketed in the XT-IDE board: Does it work if you remove the EPROM from the board? Commented May 12, 2019 at 6:45

    @MartinRosenau I haven't tried that, but the card has a ROM Enable switch. When I disabled the ROM, basic worked fine, but I couldn't boot from IDE.

    What Version is the card and what ROM address is jumpered?

  • @Raffzahn I don't know the version. The card I bought is rover.ebay.com/rover/0/0/… Everything is set to default.

    The default XT-IDE settings load the XT-IDE ROM at 0xD000, which shouldn’t cause issues with BASIC. However that doesn’t mean it should be plain sailing... You’re more likely to get an accurate answer on the XT-IDE BIOS thread on VCF. Commented May 13, 2019 at 9:10

It turns out I can just use GW BASIC instead of BASIC and BASICA. GW BASIC loads up just fine.

    For reference: BASIC is stored in ROM,. BASICA.COM is a program that loads BASIC with a number of extensions/enhancements/additional features, but it still relies on the ROM BASIC for shared functionality. GWBASIC.EXE is a self-contained program that does not depend on the ROM BASIC at all. Commented May 16, 2019 at 1:13
