From what I have read both the AMD and Intel 64bit enabled chips will run 32 bit programs if a 32 bit OS is installed and will run 64 bit programs if a 64bit OS is installed as long as your chipset and system BIOS supports 64bit architecture. We may even be able to duel-boot 32 bit Win XP Pro and Win XP Pro 64 bit Edition. You will also need 64 bit device drivers for all of your hardware when running the 64 bit OS
If you want a free 360 day trial of Windows XP Pro 64 bit Edition go to
The file name is "w2k3sp1_1218_usa_x64fre_pro.iso" (this may be a stripped down version of Windows Server 2003)
It is a 490MB ISO download!!!
If you are using dial-up it would be better to order the CD for the cost of S&H
