Long story short, I had to do a complete reinstall of Windows XP and install the drivers manually. I am down to one driver known as "Multimedia Audio Controller". I downloaded and installed the driver but got a message saying it did not have the Windows Logo but I proceeded anyway. This led to the blue screen of death so I started all over again. The info I have on it is "PCI\VEN_8086&DEV_24C5...". I have run Everest HE and it lists as Intel 82801DBM ICH4-M - AC'97 Audio Controller [A-1]. The chipset is Intel Montara-G i852GM/i852GME, etc. I can only run in Safe Mode so I am unable to start the windows audio in services or connect to the internet. Also, when I try to update the BIOS utility, I receive the following message: DEBUG - Create File () returns 2. When I try to load in any mode other than Safe, the computer freezes on the Windows startup logo or on mup.sys. My computer is an IBM Thinkpad R51 - 2888 - CTO. Any help in getting it running again would be much appreciated.
