I've been doing this for years with no problem. With 2500 Mb as the target size, I take my total ram subtract from that. For1.5gigs installed I use 1024, if2gig I use 512, and say with 1024Mb memory the number would be 1536. Now this is how I change it. I first select no page file, then select custom set initial and maximum to the same value-ie; 512 for 2gig-1024 with 1.5gig mem, and 1536 if I have 1gig memory installed. With 512 mem I don't change anything. Oh left out 768 that would be 1894. You can round off those. I just remember them that way. I don't feel any speed improvement doing this but gain harddrive space.
