Firebox problems with CPU

[Xeries]

I'm getting skips and dropouts with Sonar 6 PE and I think the reason is that my Firebox by Presonus is incompatible with my video chip - ATI Mobile Radeon 9000 IGP.

Is there possibly another driver I can download? An older version? My DAW used to work great and now it sucks. I think that ATI uploaded an update on my computer and I can't do a driver rollback.

Can't talk to a human at ATI, which is AMD either.

It says on the Presonus website that this is a common problem and there is no work around.

I can get around this by minimizing reverb. Reverb is a CPU hog.

How do I toggle effects sends in the track view so I can assign different tracks to the effects send 1 with different sends settings.

Is there a place in the manual about this? I have the Garrigus book and don't recall him going over sends and busses. I'm a newbie at this and could use all the help I can get. Thanks

If everything used to work before an ATI driver update, and your ATI chip is integrated in the motherboard, you may find older drivers on your computer manufacturer's web site. However, if it's a known compatibility issue, I wouldn't necessarily expect this to work.
