Yes, probably just as slow as it also uses the BIOS. > Is FreeDOS disk I/O in the same class as 32 & > 64 bit operating systems speed-wise? No, FreeDOS is pure 16-bit, but with Ultra DMA enabled and a software cache (e.g. UIDE) can help a lot. That's about the best you can do outside of just running under DOSEMU or similar (NTVDM). BTW, things like DOSLFN slow down file accesses a lot, so avoid them if possible. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
