4GB in windows xp pro

[Colin Barnhorst]

A ramdisk would run in the user allocation and not the memory-mapped area so
a ramdisk would not change anything. What do you think you could do with
the system allocation? Your computer isn't really cheating you out of
memory; it is using your computer too. In the old days we didn't have the
terrific video cards we have now and since no one had 4GB there was no
issue. But there was also no benefit either.

NOW YOU TELL ME!

I was wondering why taskmanager rarely rose above 400 mb. So does this
mean I need an in-memory virtual hard drive emulation utility like we had
in the bad old DOS days in order to utilize all that memory?

I actually think "cheating" is a proper word, because it does, due to

If the proper hardware was in place, you could theorize that if your
ramdisk-drive was very low level, and made changes to the page table
itself, you could then gain access to the "lost" ram
