Dual monitor prob(Intel 810 + ATI Mach64 )
 
My redhat 9.0 is running on an old machine. It has an integrated "Intel 810" video card. Now I am trying to add another video card "ATI Mach64 RAGE II" and support dual monitor.
The monitors I will be using is "DELL D1626HT" and "DELL P1110"

The problem I met is: Whenever I insert the ATI Mach64 onto the motherboard, the monitor connected to Intel810 has no output at all (black screen). But it seems the two video cards have been recognized by my computer. What is the problem?

Here is the output of
#>lspci | grep VGA
00:01.0 VGA compatible controller: Intel Corp. 82810E DC-133 CGC [Chipset Graphics Controller] (rev 03)
01:0a.0 VGA compatible controller: ATI Technologies Inc 3D Rage II+ 215GTB [Mach64 GTB] (rev 9a)


Thanks a lot,
Sean

If the card you are adding is agp, the problem is so is the onboard one

And you cant have 2 agp grafix cards in one system.

The only way i got round this was to use a pci grafix card + the onboard one, and it worked.

I think my ATI Mach64 RAGE II card (inserted one) is using a PCI slot.

Is it something wrong with BIOS setup?
My guess
