Hi Alain, Quoting Jack's comment: = Johnson -- I noticed Alain's latest "MS-DOS" comments on FD-Devel. DO confirm to Alain, as I wrote you, that my V6.22 MS-DOS does NOT "slow down" from using or not-using UMBs! If UMBs do "slow down" FreeDOS, he or others need to see WHY!Best wishes!

I received this in PVT, but I believe it may interrest... Hi Johnson, MS DOS does not use the HMA for BUFFERS as far as I know, so indeed: The 10-20% slowdown if DOS=HIGH should not happen on MS DOS. But on the other hand, buffers in HMA give you a lot more DOS RAM free :-). The real problem is
