Enable BIOS Memory Remap Option with XP 32 bit? I am in the process of upgrading my signature PC. So far Ive swapped an Asus P5B Deluxe & E6300 for an Asus P5Q Pro & E8500. Next I am going to replace the 2GB (2x1) RAM with 4GB (2x2) on the way to eventually getting VISTA 64 bit. Meanwhile Ive read conflicting info on the memory Remap BIOS option. The Asus manual e.g. says to Disable with a 32 bit OS leaving only 3GB accessible to the OS. Ive read elsewhere that its OK to Enable this option with 4GB RAM and XP 32 to get access to all 4GB although XP 32 will show use of less than 4GB. I would appreciate advice from anyone who has used 4GB of RAM with XP 32.
