I suppose that the developer s having fun doing it, because I don't see any other practical uses. It doesn't work on 808x and 286 and it seems that the developer h (...)

Code quality looks like assembler snippets generated by AI (which more often than not result on sloppy/buggy code interpretation), all these glued together to (...)

Only requirement will be that it is the 8088 compatible kernel build. That should be in https://github.com/FDOS/kernel/releases/download/ke2044/ke2044_86f32.zip. Has anyone tested that build on an 8088?

Thanks but I think I'll keep using the FLOSS debugger that we've been developing for the past 28 years. Unreasonable of course, I mean who could have use for more than peek, poke, and jump?

Still, I haven't found a compelling reason to use it. I tried v1.4 on an 8088 XT with 640 KB RAM and it was eating conventional memory like there was no tomorrow.

Yes, the 386 kernel is smaller in size than the EDR-DOS one. But it is certainly slower, at for example, startup, but not by much though (or perhaps it is just this particular 386). It seems the FreeDOS kern (...)

And we have the matching FreeDOS share as opposed to the closed source DR-DOS share that might not work correctly on FAT32 file systems.

Thanks in advance.

Fixed with an upgrade to T42 BIOS ver 3.23 (1RETDRWW, final version), which explicitly addressed USB drive letter handling.
