I've noticed that FDD won't work on Micro 8088 unless I add Sergey's Multi-Floppy BIOS Extension.

Yes, GLaBIOS by itself currently only supports "standard XT" 360K drives. This is actually a "roadmap" Issue (#5), but in the meantime there are (at least) two options:

  1. Use the Multi-Floppy BIOS Extension in the Flash image (as you have done).
  2. Use 2M-XBIOS (many have reported this work very well too).

Given that GLaBIOS is only 8 KiB, there's plenty of space in the Flash image for the Multi-Floppy BIOS extension so that's probably the simplest way to do it. It would probably make sense to include this in a distribution image, with documentation for how to alter the drive types. For what it's worth, it should work fine on the Micro 8088 without a BIOS Extension with 360K drives at least.

Again - thanks for checking it out and bringing this up. Any other thoughts, problems or suggestions - please keep sending them.

If you would like me to do any tests with your BIOS on Micro 8088, just let me know.

I guess if you get a chance to try the 2M-XBIOS and see if that works well it'd be interesting to hear. Otherwise, would love to hear any overall impressions, issues, bugs or problems.

Thank you!

Sorry for responding so late. I haven't tried the 2M-XBIOS, as this is a DOS loaded driver, and I would like to have the ability to boot from the FDD (actually I have a GOTEK/FlashFloppy FDD emulator). Actually, until recently, this was an FDD only machine.
I have flashed your latest release, combined with the Cassette BASIC, and JOINCOM ELECTRONIC FDD controller BIOS, and now it works like a charm.

That's great to hear - thanks for letting me know. If anything else comes up or have any more questions, please let me know.
