 Since most of the programs I run need EMS, I haven't checked himem.sys.
I'll check it out.

 The above suggestion is 'not' an option.
Both of my systems are 'Pure OpenDos'. And are completely free of MS.
Yes, the P150 came with W95. I deleted it. MS will no longer exist
on any of my systems. (and I do mean 'any' MS product).
