|It's not just what ME will support but what your PC will support. It's likely your PC won't properly see a drive larger than about 120 gig. Anything larger than that requires a bios that's 48-bit LBA compliant.|
ME will probably have the same limitations as 98. Again that will be about 120 gig.
There are ways around the bios limitation. The best being an add-on ATA card to connect the drive to. And a larger drive could be partitioned such that no partition is larger than 120 gig. But unless you have a good reason to put a really large drive in that thing, you're probably better off with something around 80 gig. I imagine that's bigger than the drive you have in there now.
