Keep in mind that is from the the 1.6.0 documentation. I can't seem to
locate the 1.5x version right now.
However, you are right regarding the GUI; on 1.5.6 the recommended
_base_ is 192 for WinXP, 168 for Win2K, and 512 for Vista. It's easy to
check, just start a "New" machine. I can start my Win2KP at 168MB just
fine, I just added some meg for memory intensive apps as I'm not sure
how they will react in the VM. I'll keep it running at 168 (Win2KP) and
see if I bump into any problems with app memory.
