Nothing new there!  That was true in Windows 95 for any version of DR DOS --
Caldera's, Novell's, DRI's.  The Win95 boot loader looks for a version
signature at the start of IO.SYS / IBMBIO.COM which exists in all releases
of MS- and IBM DOS, but not in DR DOS.  And that's not the only problem;
after a merry afternoon disassembling and patching Microsoft's signature
check, dual-boot *still* wouldn't work with DR DOS.  There's some difference
in the way the boot files are loaded that I haven't been able to figure out.
MS's dual-boot mechanism is just plain incompatible with DR DOS; use LOADER
instead.

I don't have a copy of Win98 yet.  But the news I hear is that there's no
fundamental change in the DOS components.  Caldera's LOADER.COM should
still work.
