I don't think there is a 2GB limit on the Mac. Older PC compatible computers had a problem b/c of their BIOS (where they couldn't access anything >528MB). However if you have a computer which was made after 1995/96 you should have no problem with the hardware. Then with Windows 95 OSR2 or Win98 or NT you should not have a problem with software either. I installed a 22gig IBM Deskstar drive on my G3 and all I had to do was install it and format it for access to the entire drive, which took about 15 minutes total.(posted 9110 days ago)Patrick
