hi, all,
I have tried several ways: change CHIPID or others to match my video card. But it failed. So I would like to ask for help:

I have two vedio card : Sis 650 and Diamond Stealth S85 ( PCI ) with Radeon 9200 Chipset. Right now I have connected the monitor to the Diamond video card. But I can't find the right driver for that, thus, I can't start X-server. My Linux is RedHat Ent WS version. Please help to solve this problem.

Thanks in advance.

I got this help, but it does not work it out for my situation:
