I have an older Gateway 7310s with an Intel D915GAG motherboard. I've used various tools to try and modify the Gateway BIOS without success. Andy's tool looks like it can open the BIOS, but it is unable to add a SLP. Intel to AMI is also unable to open the file. I found a few posts on it here and there, but with the gateway version I may be out of luck. I have seen where others have had success with the version direct from Intel, so my next goal was to get the Intel bios to flash. I know normally this is a terrible idea, but it's an older PC that I'm just tinkering with, so I'm not out anything if it bricks. This is where I ran into another dead end. Putting the jumper into recovery mode is supposed to bypass flashing checks, I have tried with the bio file on usb, cd, and floppy and it has not worked. In DOS: Intel's IFLASH tool doesn't appear to have a "force" option, and won't let me flash a different bios. Running Uniflash with the forced chip number gets a failure. Phlash17 gives back an Flashinit.bin failure. The Gateway .bio file is larger than the Intel one. Tinkering around with HxD I see that the gateway file has entries for "fixed product certificate" and "fixed flashing certificate" that the Intel one does not have. Lately I've been trying to get the correct header added to the intel BIOS, and using the program that came with the file to initiate the flash from windows. No success. I do not have enough posts for direct links, but here are some modded ones: The orginal gateway bios: h**tp://support.gateway.com/support/drivers/getFile.asp?id=20120&dscr=Intel%20%28Augsburg%29%20915G%20Motherboard%20BIOS%20UpdateRevision:%20AG91510J.15A.0816&uid=308169466 And Intel: h**p://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=10140&lang=eng&wapkw=%28915gag%29 Basically, I'm just fishing for info, something I may have missed. Perhaps a different tool to try for flashing, or a different setting. Thank you.
