Thank you Michal, that is very good advice.

I used the Win98 drivers for the P3 to see the 512MB, but this trick seems
to fail on the P4 :(

The error I get with the Win 98 driver on the P4 is:
ERROR: VDISK memory allocator already installed 

note: The exact configuration runs perfectly on a P3.

Thank you in advance,
Jacob

It's a warning only. I get it on my (Pentium-MMX) based Toshiba notebook
as well, but HIMEM works anyway.

DR-DOS memory managers (at least the latest official versions of them)
support up to 64 MB only. You may have to borrow Win9x HIMEM.SYS.

Hope this helps,

Michal
