I've been reading posts and MS sites, and see tons of info on the 3GB Switch, AWE and PAE. I understand that Win2K Advanced or Data Center is necessary to use > 2GB, but I haven't found any definitive statements on SQL edition. If I have Win2K AE and SQL2K Standard, can I use the 3GB boot.ini switch? If so, I would imagine that I could use a 4GB server, with 3GB used by SQL. The 3GB switch does NOT use AWE, which requires SQL2K EE, so it MIGHT work with SQL Standard. The reason I ask is that we have Win2K Server and SQL2K standard, and we're looking for the cheapest route to allow us to jump to 4GB. Win2K is a relatively cheap upgrade, SQL is a VERY expensive one.
