Flanders Posted January 24, 2012 Report Share Posted January 24, 2012 I am desperately trying to get XP drivers for my laptop Medion Erazer X6815. It has Intel HD and GT555M Optimus graphics. The Bios sucks because there is no option to select a desired card, it's forced as Optimus. I can install XP, I have most of the drivers needed except the GT555M. I really dont want to have to sacrifice or lose the use of the GT555M. Come on experts, someone must be able to help me. I don't know if these will help, but I copied them from Manage Hardware on Windows 7: NVIDIA GeForce GT 555M Hardware Ids PCI\VEN_10DE&DEV_0DCE&SUBSYS_20A61B0A&REV_A1 PCI\VEN_10DE&DEV_0DCE&SUBSYS_20A61B0A PCI\VEN_10DE&DEV_0DCE&CC_030000 PCI\VEN_10DE&DEV_0DCE&CC_0300 Compatible Ids PCI\VEN_10DE&DEV_0DCE&REV_A1 PCI\VEN_10DE&DEV_0DCE PCI\VEN_10DE&CC_030000 PCI\VEN_10DE&CC_0300 PCI\VEN_10DE PCI\CC_030000 PCI\CC_0300 Inf name oem10.inf Inf section Section025 Thanks in advanced :) Link to comment Share on other sites More sharing options...

Flanders Posted January 24, 2012 Author Report Share Posted January 24, 2012 Windows 7 Compatibilty mode does not work well with some legacy programs and games. I managed to get the GT555M driver installed by editing some of the INF files, and adding: %NVIDIA_DEV.0DCE.01% = Section025, PCI\VEN_10DE&DEV_0DCE&SUBSYS_20A61B0A NVIDIA_DEV.0DCE.01 = "NVIDIA GeForce GT 555M" In the different Ini sections. Yellow triangle shows up in device manager though and Control panel wouldnt install. Will keep trying though! Link to comment Share on other sites More sharing options...

tribaljet Posted November 28, 2013 Report Share Posted November 28, 2013 Optimus was designed from scratch to work with Windows 7, mainly from the inability of older OSes to handle multiple display adapters as main output devices. On an Optimus system, going from Windows 7 to XP is a significant performance and stability downgrade. Link to comment Share on other sites More sharing options...
