OK, so on Prema's advice I bought a 675MX as a trial to install 1 of the Clevo's I inherited a P150HM (previous graphics card is 560m - still working, I also have 2 other P150HMs with burnt out 6990m's which I will try later, I figure if the bios is already expecting an NVIDIA card maybe the process will be simpler, then I can just change it into other PC), which should be winging it's way to me in the next week or so. I picked this board as it was cheap (£25 on ebay) It is I think a Dell model (lienware M17x R4), but I understand the VBIOS can be flashed using one of the MSI links from Riri-Fifi. As this will be my first VBIOS flash, is there anything I am missing, will it be blind flash or does it have to be done pre-install from another computer. I think there is onboard Intel 3000 chip on CPU so could the machine be booted from this then flashed or will I need dual GPU machine? Thanks for any input and sorry for the newb questions if this has already been answered elsewhere.
