Dear Alan,When I extracted the vga bios for my nvidia geforce 8400 gs, i went into BIOS to set PEG as the primary video adapter. Then I booted using nvidia gfx and extracted the vga bios using nvflash.exe. I believe it is possible to use a hex editor to examine the vga firmware file to see if it's the vga bios for nvidia. -- Mr. Teo En Ming (Zhang Enming) Dip(Mechatronics Engineering) BEng(Hons)(Mechanical Engineering) Technical Support Engineer Information Technology Department Asiasoft Online Pte Ltd Tampines Central 1 #04-01 Tampines Plaza Singapore 529541 Republic of Singapore Mobile: +65-9648-9798 MSN: teoenming@xxxxxxxxxxx Alma Maters: Singapore Polytechnic, National University of Singapore On 08/29/2009 12:36 AM, Alan Cox wrote: I believe the VGA BIOS in the physical memory region 0xC0000 to 0xC7FFF is the vga bios of onboard Intel graphics, and not my Geforce 8400 GS.If that was your boot video device. To extract the video BIOS for the Nvidia you either need to map it and read it out or boot with the Nvidia as the boot video device to acquire it and then switch back. That ought to work.
