How does ASUS Crash Free BIOS 3 Work?

I wonder how does ASUS Crash Free BIOS 3 work? Does it work from something independent of the BIOS itself? Since if the BIOS is corrupt, how does anything run from it? I have an ASUS H67M which I might have accidentally flashed with the BIOS ROM for the PRO version, my mistake, I know. But now, should Crash Free BIOS run? I expect so? But I don't see anything when I start my PC, what might be the problem?

  1. There might be hardware issue. You should flash your bios carefully.
  2. Yes I understand I should have been more careful. I think what happened was I googled "ASUS H67-M" then the 1st result was with PRO but I probably didn't notice. Too much trust in Google ... the download BIOS and flash ...

    But the point of the question is to understand why might this feature not be working? Is it flawed? I know I might have flashed the wrong BIOS, but I think CrashFree should detect that BIOS is not working and kick in? My guess is CrashFree is part of the BIOS or something?

    Looks like Gigabyte's DualBIOS is more reliable in this case as its a duplicate physical hardware chip?
  3. To use crashfree bios 3, you need to insert asus support dvd or USB drive that contain bios file. Then utility system automatically check for bios file and start EZ flash 2 utility. After bios flash, always us load default setting.

    And yes Gigabyte has backup bios to recover it successfully if main bios is corrupt.
  4. I tried downloading BIOS, renamed it and put it in a FAT32 thumb drive boot nothing happens, nothing on screen. I think I should see the CrashFree BIOS messages on screen telling me to do something even when I didn't connect any USB or put in any CD?
  5. Try with not renaming it. If not telling anything from bios then you should RMA the mobo.
  6. By If not telling anything, I suppose you mean if the BIOS screen does not appear? If I dont plug in anything (flash drive) should I at least see some "BIOS corrupt" message?
  7. Depends on bios type. Do you see anything in screen after boot or after asus support dvd insert?
  8. I dont have the DVD (probably lost it), but I did try the USB route which is supposed to work? Nothing on screen whether or not I plug in the USB
  9. You should RMA it then.

    Unless there is necessary, dont do bios update. It will not increase system performance as driver do. Just for better cpu support and feature update. If you are fine with hardware, then dont do bios update.
  10. I was thinking the slow POST sometimes might be because of BIOS, noticed it seems to have something to do with Walcom Tablet plugged in. So I tried doing an update ... thinking it might help. The ASUS website did mention something about increased USB compatibility.

    To use asus's crash free bios 3 you must:

    Insert the Support Disc into the optical drive or insert a usb with the bios file inside

    You must use vga or dvi directly plugged in into the motherboard

    After CrashFree BIOS 3 starts working, you will hear 2 short "beeps" sound indicating that the BIOS file is recognized. If you hear 5 short "beeps", it mean no BIOS file is found. Please check whether the Support Disc is the right one for your motherboard, or make sure your optical drive is fully functional.
    After hearing 2 short beeps, please wait 4 minutes for the CrashFree BIOS 3 operation to complete.
    Restart your system.
  12. Does it mean that CrashFree BIOS 3 is also on the motherboard but not part of the BIOS?
