    Default How does Gigabyte dual BIOS work?

    Say you are overclocking and it fails. The machine boots up with the settings you had so you can fix them. I have seen this but never had it happen. What should you do if this happens, or if you get a BSOD?

    Do you need to re-flash the BIOS? Will the back-up BIOS still be there?
    How does it work if anyone knows? I can't figure out how it would use the back-up and still have the back-up BIOS working after it saves you.

    I know the website says there is no way to flash the back-up BIOS yourself so, does it revert back to the original?

    Thanks

    From my understanding your cant make any changes to the back up bios like its read only. If a over clock fails where it kicks in the back up bios it reflashes the main bios to default settings reboots then it will post allowing you to renter the bios and let you make what ever changes you need and try again.

    I have yet to see my board kick in the back up bios yet. I have had it go into a boot loop of about 3-5 loops and I have just hit the PSU power switch on the back. Or it just fails to post shut down fail to post shut down then boot but still be from main bios but with defualt settings and then the BIG RED error box once you go into M.I.T.

    I hate to admit this but about 8 months ago I tried starting a P45-UD3P with NO RAM installed. It (of course) would not start and I realized very soon what I had done. I saw the "red box" next time I went to the MIT.

    I have seen someone put 500 FSB in the same board with no voltage change and it started. I assume from the backup BIOS. It still had his settings there. (500 FSB) so he could change it.

    I just wonder how the dual BIOS is set up. If you flash a BIOS and the power goes out....will it revert to the backup?

    I sure wish they had it set up so you could control what was on the backup chip. I can see why they don't do it. There are a lot of idiots out there. (like guys who use no RAM in their machines) but really...it would be nice to control.

    I have had my board and cpu up to 500 fsb. It wont even think about booting at default voltages at those speeds.

    I dont know on other gigabyte boards but on the ep45-ud3p my board came with bios F6 on the main and back up. From what I know if you update to F9 you are still stuck with F6 on the back up. Untill F10e came along and Gigabyte update Q-flash so it had to update the back up bios to be compatible. But your main bios is stuck at F10e you can go up to F10f but to go back before F10e its not for the weak hearted.

    How did you go about updating your backup BIOS. I understand this is not possible. Is there a way to do it? Gigabyte says it can't be done manually, however this makes no sense since you may use a CPU that was not compatible with the shipping BIOS. Either you can do it manually or the flash utility does it behind the scene. Is this what you are describing? Q-Flash does it for you?

    What happens is if for some reason the (M) bios gets corupted you see a message "BIOS CHECKSUM ERROR...RECOVERING then the (B) bios will flash the (M) bios and you will be back up and running. Although sometimes the (M) bios will partly flash and get into a loop. Then you will need to PM Lsdmeasap to get a diagram and instructions to jump a certain bios connection (either 4 and 7 or 5 and 6 depending) on the (M) bios. Then power up to force a checksum error. Then B bios will flash (M) bios. Either way it beats a brick.

    Very good, thanks for the info. Dual BIOS is one of the other reasons I keep going with Gigabyte. I almost CAN'T go with another company now. Gigabyte is like crack. haha Honestly, thanks for the info....I hope I never have to use it.

    I can't believe every company does not have dual bios, and something like q-flash. I understand another large mobo company still makes you download a flash utility. Unbelievable. I suppose if you were used to that, it would be easy too. Gigabyte just seems to have the motherboard business figured out. They ARE NOT perfect by any means. I have issues with my new P55-UD4P but most are fixed and I can flash the new BIOS so easy.

    Normally you cant update the back up bios. except for when they update q-flash or at least thats the reason it was said to have happened for F10e bios for ep45-ud3p. To update the back up bios it is said that you press ALT+F12 at post and will give you the option to update bios. I dont know if this is for every gigabyte board with every bios revision. But when updating to F10e it automatically did this with out user input.

    Oh, alt+f12 oaky. I will not do it but I have been wondering about my new board. It says you can use f11 to save current BIOS settings to a profile (8 profiles total) that seems nice and I will be using that. Then you use f12 to load a saved profile. Has anyone tried this? Does it work okay? Is this why the new P55 boards are 2MB instead of 1MB. That's what I'm thinking. I have not ever seen this done and wonder if it works okay.

    I see....I wonder if they have made a change on the new boards. It says from the main menu you can press f11 to save current settings to a profile. I don't think this was on my last board (P45-UD3P) i might be wrong. I can't wait to try it out.

    Edit: It IS on my last board. I just never noticed it. cool!

    Thanks for all the info. I really need it.
