FreeDOS is DOS compatible, of course not 100% but most of the program

It's because the UltraDMA mode disabled in BIOS, download UDMA2 from

The FreeDOS kernel and command.com was smaller, and boot a lot faster

The only tweak maybe in FDCONFIG.SYS (you can use CONFIG.SYS also):


will use 6 buffers, otherwise it consume 29 buffers whatever the
number is, why? Have to ask the developers ;-)
