that is the D845GRG, if yours is different, please tell us where it's different. The D848PFT2 is NOT listed on the Intel website. I have a feeling this is an OEM-only board made for Toshiba only by Intel. Please provide additional info on the board like perhaps the bios id string.
Also, you didn't state what your wanting... bios or drivers?
If drivers are what your wanting, please use a software hardware id program like Belarc Advisor and it will id your hardware...

Once you know what hardware is onboard, it's much easier to locate drivers.
