I almost feel ashamed to post in this thread, but just in case it helps...
I have an ATI 9800se 'All in Wonder' graphics card - yes, I know, but I wanted the TV tuner & a full, not 'se' AIW9800 was big bucks, at the time...
I heard of a 'softmod' driver that would turn on the extra 4 pipelines on the card & make it nearly equivalent to a full 9800 card, but the driver only worked with windows xp - I had win98se...
But then - I recently upgraded to XP and decided to try it.
I found uninstalling all existing drivers was the way to go - once the softmod driver & WDM files were installed in a 'clean' system I loaded my multimedia (MMC) package as another seperate install, using the cd supplied with the card. The trick here was using <shift> to avoid the autorun installation, which in my case kept overwriting the modded driver - groundhog day, anyone...
- so, running just the MMC install from the original cd restored my TV player
- and my 3dmark3 score is now 5381 (athlon 2600, 512MB pc3200, 40GB 7200rpm ide)
nowhere near our 'bleeding edge' members, but, hey, I am old enough to be easily pleased
