Someday I'll try to make this a bit more automatic. > Under OSF I made it go hunting if it thought that there might be more.. basically, if the BIOS says 64MB (well I use >=63MB as I don't trust Bios's) I do memory tests upwards till I start getting failures.. The trick is to do this BEFORE YOU SWITCH ON PAGING so that you don't get pagefaults.. I could send you the code but it PROBABLY doesn't apply directly, and you'd probably do better implimenting it yourself once you've heard the idea of how I did it.. > -DG >
