Hello Alain,
I just made some tests with UDMA2 and had some unexpected results:
Why is FreeDOS so much slower (60% no UDMA, 14% with UDMA)???
this may depend on
file placement and free space fragmentation as
well, where MSDOS uses an alghorithm other then freedos
what EXACTLY is

emmx203.zip, EMM386/HIMEM mostly executable package, and emms203.zip,
EMM386/HIMEM mostly source package.
EMM386 Version 2.03 is a minor update, recommended for those using programs
which are bound to the WDOSX DOS

I just tested, it is working fine.

Hi all,
Thanks for all the feedback. I spent all day making tests, the data is
very confusing, I will make more tests and some kind of report on friday.
Just a few points: emm386 is not responsible for most of the slow-down,
most of the time umbpci behaves the same (?) and different
