Thanks James. If I'm not mistaken you've covered this point in other posts --- point being - configuring XP to use more ram. I've always thought that XP (with all service packs) automatically uses all the ram available, up to the max 4GB. Different systems show different ram available, 3.25, 3.5, 3.6 depending upon hardware config. (that counts graphics card, sound, and size of page file?) Doesn't sound like it worth the trouble of a screwy or failed boot.:sign_thanks:
It's not actually about how much RAM the OS uses, but about how it divides up the
virtual 4GB that every process has on a 32bit OS. Normally it's 2GB for the program, 2GB for the OS. The special option makes it 3GB and 1GB. It is the squashing of the OS side down to 1GB which can potentially cause problems.
