It's a D945GPR, basically VGCRB60G's proprietor board. If you read my earliest post just a page or 2 back I got the link from this thread. I want to be able to get my original bios back not just the chipset driver. Sony doesnt have the original bios unfortunately so myintegrated sigma tel high definition audio doesn't seem to be functioning no matter what unless revert back to the original or more compatible bios.
The @larat's *.BIO file that you flashed with is in fact the original bios extracted from his board, not a modded one. Unless you get hold of the original bios there is no way to fix the problem.
