Try the other option for this entry. Be aware that a few BIOS's didn't implement this proper so I wouldn't be surprised if that didn't fix it. Tell me which BIOS version you have and what is their latest offering.
booting up is not the problem, its the way it does it.. system specs first:
AMD ATHLON 64 3200+
Biostar/GeForce 6100 motherboard
Visiontek Xtasy Radeon x1300 pci 256mb ddr
windows xp professional
latest bios updates
the motherboard has onboard video which sucks so i use my radeon which is awesome. when i boot up the monitor has no signal or ''no video input'' until the logon screen comes up then its fine. but if i use the onboard for display its fine. if i disable onboard video then it boots up past bios options and xp loading bar then turns black. so if i had to use bios i have to switch from my radeon to my onboard card. i've reset bios settings with jumper and within the bios, the init. display is set as pci. i've reinstalled video drivers and everything. i dont know what the hell the problem is. my card worked fine on my old intel 1.1ghz system.
