Hello, i have a motherboard Gigabyte X470 Ultra Gaming. I have the new BIOS F51 BIOS with Dell SLIC 2.5 susessfully made With rufus a bootable stick made
If i try to flash with standartd efiflash programm, i get fehler "Invalid BIOS Image" If I try to flash in dos I get "This program cannot be run in dos mode." Can someone please help? Appreciate if someone could add efiflash to post so I can SLIC my bios.
I updated my Gigabyte Z390 BIOS with a beta BIOS and now when I try to flash an official BIOS I get oemid mismatch error. I tried the hex editor to bypass the oemid block but no go same error. Can I flash the latest official BIOS using the EFIFLASH tool? If so, I need some details on which EFI tool to use such as the .85 mod or standard .85 and EFI or BIOS mode. Does the BIOS need to be named BIOS.BIN on the flash drive. I haven’t done any BIOS moding or flashing in years so I am very rusty. I don’t plan of flashing both BIOSs right now but just the main BIOS. If the flash works and everything is OK then I can try to flash both of them perhaps at the same time. Suggestions and details?
Switch options for Efiflash.exe: /C - Clear DMI data. (default: Keep DMI data) << Use this /S - Save Original BIOS Image to Disk /R - Reboot System after BIOS Update /DB- Update both main & backup BIOS << Use on second reflash, if/when you want to flash both
You can use stock BIOS name.extension, you do not need to rename >> Usage : efiflash [Input or Output File Name] [Command]…
Thanks. That one works with the Ga z270x gaming 7. Flashed the coffeelake tool patched f5 bios for the option that includes the i3 8350k with efiflash mod .87. I probably did something wrong though, the pc doesn’t turn on(turns off automatically in 5 sec, debug code 18) with the coffee lake cpu but it does boot normally with a g4560 i used to flash the bios. I’m thinking it was because i didn’t isolate the pads, thinking it wasn’t necessary due to the picture in the coffee lake tool thread, with i3 8350k not needing shorted or isolated pin. I was reading that gigabyte boards like z170, need to have a certain you need to pins isolated for the computer to boot? Is that the case with z270 gigabyte?
@Tim52 The 8350K (B0 revision) does not need isolation and Gigabyte boards don’t require the SKT_OCC (socket occupied) mod either so there is likely a problem with the mod BIOS. Did you add a microcode for CPUID 906EB?
Thank You! I opened the modded bios (modded with win raid tool, option for b0 cpu) with coffee time and added the microcode you suggested to the bios. Now my ga 270x gaming 7 and i3 8350k work now . Now I’m running a full ghetto build with a p106 gpu(edited gpu drivers) and a z270 modded bios motherboard with 8th gen cpus. Thanks again @chinobino
