Thinkpad T400: Fix 0×0000007E pci.sys error
When installing Windows XP on Lenovo Thinkpad T400 laptop then an error message appear and said STOP: 0×0000007E pci.sys error. The one T400 user getting this problem after deletes original partitions and makes it enable to install XP. But then after booted from a CD and as Windows XP loads he’s got pci.sys error in T400 laptop. He’s already tried to set shadowing disable, changed the HD to compatibility, and core multi-processing is also disabled but the problem still comes.
If you want to fix STOP: 0×0000007E pci.sys error in your Lenovo T400, the first thing you need to know what version of Windows XP disc you are using. Is the version of RTM, SP1, SP2 or SP3? Seems like this issue come because of a PCIe issue which requires installation using a SP2 or later slipstreamed disc. In case your XP disc is an earlier version then slipstream the latest service pack and then try the installation. After changed the version of the install CD, you should see that now it’s running properly.
