MSDOS.SYS + IO.SYS = MS-DOS
KERNEL.SYS = FreeDOS

Wait until rr gets back from hiatus, see what he says. I find it hard to believe it wasn't tested under FreeDOS also.

Barely. It runs almost everything. There are some corner cases, however (as nothing is perfect). But overall FreeDOS is indeed quite good (IMHO)!

Large? No, definitely not. But some obscure things will exist, surely.

Please don't. The only reason to (ever) give up on FreeDOS is if it's no longer developed. (Ahem, MS, DR.) And even then, it still "mostly" works! ;-)

MS-DOS can't read USB either. So your BIOS must be emulating a HD there. SATA is almost definitely running in compatibility mode. (Don't) try MS FDISK with your SATA drive or (don't) try to create FAT32 without mucking up other partitions. ;-)

EDR-DOS is a valiant effort, but the license is less than ideal, and Caldera / Lineo really screwed the pooch by not releasing a fully patched version. (7.01 had known bugs, even some long fixed by Novell.) It's a shame, the idea was sound, but not everybody can be the next Linux.
