I've got XP x64 edition installed as my main OS, but I want to be able to simultaneously run XP 32
The reasons are:
occasionally, some programs won't run on XP x64 (though the vast majority will). Mostly, these are older games from the Windows 98 era.
My USB wireless card does not have drivers for XP x64 (it has an Atheros AR5523 chip)
Anyway, I tried using Microsoft Virtual PC, and I also tried using VMware (using XP x64 as host OS). But so far, I haven't got it working the way I'd like.
I haven't got either program to utilize my USB wireless card, or all six of my hard drives. And, it won't share CPU time between both OS's. It'll just reserve one core for virtualisation.
I've got 4GB RAM, an X2 6000+ at 3450MHZ, 2 x 3870's in crossfire, and 6 hard drives (4x750GB, 1x320GB, 1x74GB Raptor).
I may upgrade to 8GB RAM if I can get Virtualisation working properly.
