Search the FreeDOS FAQ, I'm pretty sure somebody had a similar problem. Or e-mail Eric Auer, I think he figured it out back then (hopefully still remembers).

Use whatever you want. It's just that modern hardware is intentionally less friendly to DOS. :-/

Various DOS file managers (e.g. NDN or DOSZip) support LFNs too! :-) As for FAT32 LFNs (and exFAT), that's almost definitely due to patents by MS. (Dumb dumb dumb! Seriously, Linux supports like 40+ FSs! None encumbered, last I checked. MS is really stupid here.)

Allegro supports VBE/AF, which does support (very few, limited) old cards like my P166's ATI Mach64. Good for e.g. Doom: Eternity engine + FreeDoom. ;-)

Good, 'cause Allegro doesn't support DOS anymore. :lol:
