The 64MB Barrier?
Ok, if the BIOS is counting the 128M you're half way there. The statement "it's
a DOS limitation" isn't quite right. First of all, DOS can only address a
single megabyte. That said, anything beyond that isn't going to be used by DOS
at all.
The old HIMEM.SYS (the one in Windows 3.1) is limited to 16 or 64 megabytes
(depending which version you have). The new HIMEM.SYS included with Windows for
Workgroups doesn't have that limitation. QUEMM has the same problem but you can
override that by telling it how much memory you got (you do that by adding
EMB=131072 at the QEMM command line).
I have 72M in one of my machines and I don't have to do anything special to
access that.
Do either of the above and let me know if you still can't access 128M from 3D
Studio.
