YaY my G400 is up and running!

[The Rev]

I had a very easy install with the G400 32MB SH OEM. My (not so detailed) setup is as follows:
Celeron 300A @ 450
128MB CAS2 PC100 RAM
G400 32MB sh NOT OCed (yet
Abit BX6-2 using KH version and an 128 AGP aperature size
Diamond MX300 using Aureals new reference drivers

I formatted my hard-drive and installed Win98SE. Once up and running I installed the 5.13 drivers. I noticed the beautiful tech demo running slow. Then I installed 5.15 on top of it. I did not uninstall 5.13. Was that a no-no? Well the tech demo runs smoothly now. In Starsiege Tribes (a game I hear G400 doesnt run well on), it isnt playable in OpenGL, but I can play it in D3D fine. At 1024x768 it slows down very slightly though. This is with all detail on btw. I was wondering what are some good tweaks to use for my G400 to get it at peak performance? Also, should I uninstall 5.15 and reinstall it since I didnt do a clean isntall last time? I'm also not sure whta aperature size to use in my BIOS. Need to learn how to tweak this thing well!

Thanks for the help,

P.S. I LOVE that tech demo! Simply awesome.

Oh yeah, I hear alot about IRQ conflicts. The only thing sharing an IRC with my G400 is the PCI Steering bus. Is that normal/good?

Sorry for the 20 questions
