PCI bus conflict apparently causing Win95 lockup
Posted on 1998-07-04
How do I detect a correct an apparent PCI bus conflict which causes Win95 to hang during bootup? I recently added a Creative Labs 3D Blaster Voodoo2 to my system, precipitating this problem. The Diamond Video VRAM card has a know conflict with the 3D Blaster which was supposedly fixed by running a utility (S3fixv2.exe) which apparently changes the values in address registers on one of the cards. After accomplishing the remap operation, the utiltity then spit a message to the effect that the 3D Blaster/Diamond conflict was fixed but that it had detected another PCI bus conflict that is unrelated to the 3D Blaster card. Win95 now hangs with a gray screen after the Windows 95 flag screen disappears! Arrrrrgggggggg!
The only approach that I know of is to tear down the machine and install one board at a time, letting Win95 detect and install it to see where it fails. Bummer!
