First I tried a 166 MMX OCed to 266 with 64 Meg SDRAM. Working pretty good. Then I got it running on a non OCed 166 MMX chip with 64 MB 72 Pin RAM. So far, it's running pretty good on that system. Don't have the pretty taskbar and everything. Got it running in simple mode now. Anybody install XP on a weaker system than THAT?
