    Cool, well no matter how it was fixed it's great to see you got it going!

    I do suggest the latest BIOS if you are not using it already, and since it recovered it may have recovered a very old version. Update to the latest BIOS and you should see the setting, I think it's added to X38 by now anyway.

    All the recovery options follow the same procedure, HDD, then CD, then backup BIOS chip, and no there isn't anyway to adjust this other than to not make a HDD backup via the setting I mentioned. It just does not always work as easy as it should.

    Unbrick 4+7 works every time, the other one does not.

    If your system started hanging it could be failing memory or OS driver issues, have you tested your memory lately? Might just need some minor adjustments.

    It happend to my Ep45 too, it didn't even bother if hdd image is not seen, switching to next source. After unplugging the HDD it had no reason to look for image on HDD and the backup bios restore was initiated. It happened because I set some insane low 1.75 voltage at 1000Mhz DDR2 combined with something else, instant bios corruption. Funny thing is it had no problem running stable at 1.75 in windows lowered by easy tune, so i must have lowered PLL, VTT to 1.1V too in bios and tried to boot. I believe that voltage too low could cause the same thing as too high, some VTT/PLL/DRAM/MCH combinations just don't run well together. just like if MCH is 1.14 and Dram 1.94 it results DIMM fine delay of 10-0-10-0, and 1.14 1.96 does 9-6-10-0, and so on, 1.16 goes with 1.96 well together as 10-0-10-0 is set. If PLL is lowered to 1.15 and VTT to 1.15 while 500 FSB, then again 9-6-10-0, despite being stable it eventually fails the tests after 100-200 iterations or who knows.

    I believe fine DIMM delay (as seen by everest:chipset) could be considered some sort of health indicator for memory stability.

    From the EP45-UD3P (rev 1.0) user manual:
    Page 49, Advanced BIOS Features:
    Dual BIOS Recovery Source ------ [HPA] --> near the bottom of the screen after Full Screen Logo Show

    Page 51 description says that HPA is the default setting.
    I don't think that [CTRL + F1] needs to be pressed from the main bios screen to see this option.

    OK, thanks for everyone's input.

    Just to round this one off. I upgraded to latest BIOS, F10, (my board is rev 1.1 btw). I can now see that option that enables/disables writing of BIOS image to the harddrive. I enabled it.

    I assume there was no image written there before as recovery procedure did not pick one up. Maybe the "Dual BIOS Recovery Source" option that profJim referred was still at it's default value of HPA but as there was no image there then it would not recover, (even when disconnecting the hard drive). It did eventually recover (from the backup BIOS) after swapping memory modules, clearing CMOS, many reboots, and just leaving it a lone for a couple of hours.

    With this new F10 BIOS I'm hoping it will automatically look for a backup BIOS in the other location if it can't find one in the default location (as specified by "Dual BIOS Recovery Source" option.

    HPA means it will backup to the hard drive, do not enabled this if you are using RAID and have already setup an array. If you have not built your array yet it is ok to enable, but not after

    (This is just a note for anyone reading later)
