Using WinXP Pro 64 Beta and WinXP PRO SP2?

Question

I could not get Games (Half life, Counter Strike, Doom) to work using my beta system. Every time I launch a game the OS gives me the DEP error. I select "allow all". Still no go.
I installed the HD from my old Pentium Based PC(as slave)which is loaded with WinXP Pro SP2 and everything else in the world. I don't have the origional CD because it was loaned to me from my company(Which is why I loaded Beta to this AMD system in the first place). I work from home sometimes. (good excuse?).
I can see all of the files in the old drive using explorer. I tried launching the games from the explorer and got the same negative results.
How do I get the correct Via, AMD, MSI, etc drivers on my XP-32 bit HD so I can boot to it?
Is There a way to run both OS at same time. This chip is hypertheading, so theoretically it acts like two processors?
I now have 3 80G HD. One with WinXP ProSP2, One, 64-bit Beta, One on SATA drive with XP Home SP2 (unregistered)lost that key too--it was a disk that came with a Dell Laptop.

hi
you should really do a clean install for the OSes as the CPUs are differant and need differant drivers etc, most poeple who try to transfer HDDs have probs, until the re partition, format and install.
Many systems can co exist, the boot under XP 64 will find installations and form a boot screen to access them all.  Your going to need a XP CD to reinstall I fear. but then you might be lucky,  if you formatted 1 disk, loaded XP 64 bit edition and let it set the C:> drive with Boot files and drivers you might get away with it.
