Hello there. I have a IBM Thinkpad R40, MBO: IBM 272326G, Chipset Intel Odem i855PM. These are the exact driver for my model: http/www-307.ibm.com/pc/support/site.wss/product.do?template=/product.do?template=%2Fproductpage%2Flandingpages%2FproductPageLandingPage.vm&sitestyle=lenovo&brandind=10&familyind=113090&machineind=117667&modelind=118127&partnumberind=0&subcategoryind=0&doctypeind=9&doccategoryind=0&operatingsystemind=53385&validate=true. I can't install the sound card because i get a error message: "driver not found reboot your system and run this again". I updated my bios, i downloaded the last sound driver, i scanned for viruses, i reinstalled my OS. I'm out of options. HELP ME PLS I'M DESPERATE !
