From: Bob Wilson on 20 Feb 2010 04:33 Thanks to all who wrote on this. No, there's not a BIOS option for two monitors, just AUTO or PCI or the onboard. AUTO makes Windows boot up on the PCI (ATI Rage) adapter. There's also no option to disable the onboard adapter, only to select the primary monitor. There are some DVMT settings and I don't know what that means, but I tried all of them. I have uninstalled both adapters in Device Manager and let it detect them, but if it's not the primary one, it won't let me install a driver. I did get it to do something different though -- now when I set the BIOS with the onboard adapter as primary, it starts to boot off the onboard adapter and when XP starts to load, the PCI monitor says "1: DSUB Cannot display this mode" and the onboard monitor goes black.. I did download the newer ATI drivers, and they installed just fine -- when I was running on the ATI adapter. I wanted to boot to the onboard adapter and re-install the ATI drivers when Device Manager said they were not installed (whichever adapter is not set as primary in the BIOS, XP says the drivers aren't installed and they won't install). But now I can't boot off the onboard adapter at all. I reset the BIOS to defaults, and got off the KVM and put mouse, keyboard and both monitors directly to the PC, and it's still not letting me boot off the onboard. The whole problem with this deal is in XP Pro -- I installed it with a hardware / BIOS config that was the same as the one that had been working just fine with the earlier install of XP Pro.

From: Andy on 20 Feb 2010 23:17 In order for the Rage Pro to function in dual monitors under XP, it has to be the primary display, because its bios has to run during power up to initialize the card. If it's not primary, the card won't run.

I've used, Matrox, Ati and currently using Nvidea, they were all fine "Bob Wilson" <roverdrover(a)gmail.com> wrote in message news:143dd5d1-5d4e-464a-9de1-de785e444e23(a)f15g2000yqe.googlegroups.com...
