Hey Jav.
Windows 2000 has a boot manager so it will let you run multiple operating systems. You choose which one you want at boot up. The operating systems share resources like periferals and system drivers(motherboard, chipset) but they dont share drivers for audio, video, ect. So I have to do everything at least twice but as soon as I get a new audio card Im ditching 98.
I got really good performance with the older detonator drivers, Im just always messing with this machine. Most of my trouble started when I used the 28.90. Ive gone back to 28.32 which worked great before but now Im still having alot of dropped frames. I thought about more memory but Im going to overhaul my system soon with XP processor and DDR.
The 29.11 drivers also screwed up Motherboard Monitor so I had to reinstall it.
