What I can do is give you a search vector. I found some Pascal code
which is a part of SWAG (Sourceware Archival Group). You can get
the SWAG program library from any good BBS. I hope you are familiar
with Pascal so you can translate the code. But I must warn you, a lot
of this code is machine code.
Here follows some Pascal code for detecting XMS/EMS. After that code
follows some information how to get the EMS/EXM amount from de CMOS
setup ram. What I learned from the Pascal code: it is difficult to
determine how fast the CPU is running. It is all on empirical base.
Good luck,
Marcel Kollenaar
