I am currently trying to install a new ATI radeon 4350 PCI graphics card into an industrial PC with an existing onboard ATI Rage XL graphics card. The purpose of the new graphics card is to peform stream computing i.e. I want the old graphics card to continue to do the graphics processing and the new card to do my parallel processing.
The problem I have is that when I install the new graphics card it looks like the bios disables the onboard card straight away and uses the new card. I can still see the old card in Device Manager but when I enable it, it tells me that the device cannot be started. I have tried disabling the new card in Device Manager but everytime the bios must kick in and re-enable it.
Is there anyway to fix this problem?
