    Cross-Flashing BIOS: Intel915GAV to Asus P5GV-MX

    I have an Asus P5GV-MX board which is based on the Intel 915GV chipset.

    The Asus board will not recognize SCSI as a boot option, but the Intel 915GAV board I am writing this on, does.

    Has anyone here cross-flashed Asus boards successfully.

    I downloaded the Intel Bios and want to install it on the Asus board.

    Any cautions, suggestions or other info welcome.

      It won't work unless the hardware is absolutely identical.

      This incudes details like the model of the clock generator and how the GPIOs are connected on the southbridge.

      It may be easier to enable the option in the BIOS using a tool like MODBIN6 (Award BIOS only), or only change the boot module.

          Not true, you could force flash it if you have the right software but I would not do it with a Intel bios and would make sure you had a backup bios chip to replace the one you are going to most likelly brick. Try flashing it with another ASUS bios that is really close to your board with the features enabled you want.

          Better safe than sorry.

              [TUTORIAL] fix asus bios with bios from asus web support (by razor_amd)
              by razor_amd
              With ASUS, not everything is quite so simple. I will show you my way. It may be longer or harder but it is the right way to do it in my humble opinion.

              For example, you can have 3 similar ASUS motherboards, all being the same model, all of which will have different BIOS versions.

              I will give you an example and my version of preparing BIOS from ASUS website and in the process I am always cleaning Intel ME while doing it so you have fully cleaned BIOS, no DMI data, no password, nothing.

              This is the picture of 3 similar ASUS motherboards, all of them being X555LD...

              ASUS TUF GAMING Z790-PLUS WIFI - BIOS Help
              by grimacelord
              Hello,

              I have spent the last hour on this and I guess this is just over my head, so here I am.

              I have an ASUS TUF GAMING Z790-PLUS WIFI motherboard here that needs to have the BIOS updated in order to accept the latest CPUs.

              The BIOS chips seem to come as a set of two: GD25B64ESIG and GD25B128ESIG. My guess is one of them is a fail-safe for the main BIOS? I really don't know. Or one of them is ME and other is BIOS? I don't know.

              Anyway, I took dumps of both chips and then downloaded the latest update for this motherboard from ASUS's website...

              Asus ROG Ally X -RC72LA - changed hidden bios settings with 'Smokeless-UMAF', won't get past boot logo
              by throwaway327
              ASUS ROG Ally X - (Handheld Gaming PC)
              Model No: RC72LA
              Serial No: SBNVKD001014459

              Hi all, I've spent the past week digging through the forums and guides to try correct my foolish mistake of changing hidden settings while tinkering around, and to be honest my heads overloaded so I'm hoping you'll be able to help.

              I used a tool called 'Smokeless-UMAF' to access usually hidden settings in the bios. I tweaked one or two 'safe' things but made the mistake of tweaking a lot of settings under 'USB/Thunderbolt Configurations' when I didn't know what they did. For...

              ASUS TP500LA BIOS request/repair/merge?
              by jbonavita
              Hi, my laptop wont boot at all
              With original bios no POST, only LED lights
              With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
              Some issues
              A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
              B- If updated from 500LN version 203 to 300, the battery stops being recognized

              Things I tried

              1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...
