Mack1982 Posted September 15, 2008 Report Share Posted September 15, 2008 Hi, I like so many others, I also tried to upgrade from my 8400M G to 8600M GT 512. However, after installation I can't seem to flash the BIOS. When I start the notebook, it asks me to reflash the MXM and then when windows starts, the resolution is at its mininum. If Vista autmatically installs the driver, i get the BSOD. I followed the following steps: i have not tried it but i think he did it this way1. download hp boot key and create a bootable usb 2. download nvflash 3. download 8600M GT bios 4. extract nvflash to root drive of flash drive, copy also the bios in the root drive 5. restart pc and in bios set flash drive as boot drive (F12 key usually) 6. on command prompt type "nvflash -b backup.rom', now you have a backup bios file named backup.rom 7. on command prompt type "nvflash Acer.8600MGT.512.070423.bin -4 -5 -6", wait for it dont touch nothin till it finishes up good luck However, I can't flash the .BIN file. NVflash says the file should be of type .ROM and some other. Any Advice. Quote Link to comment Share on other sites More sharing options...
