Thanks for the procedure, but it didn't work for me. Time for a new mobo.
Failed BIOS Update Recovery
I had a recent Dell bios update that failed and wish to pass on the recovery method to you.
After visiting the Dell support website and directly getting the latest bios update, mine being from A02(old) to A08(new) it will be a worthwhile update. However, Dell didn't immediately at the direct d/l webpage supply any instructions to its install. Past experience after getting the bios update allows the actual update be .EXE file self-installing, block by block and then reboot or allow a reboot to complete the task. In my case, it never finished and froze prior to completion. Later investigation offered that this bios update should be done from a bootable USB device, floppy or flash drive with required files.
What you need for recovery
*NOTE* the bios update was Phonix bios based, but can also be done for an Award bios update, pay attention to any special needs as they do vary but overall are similar. YES!, other laptop makers follow similar recovery methods
1) latest bios update from PC maker
2) wincrisis recovery tool (Phoenix supplied)
3) HPUSB formatter(optional), Windows own formatter works also
4) ext. USB flash drive 1gb works but no bigger than 4gb(I used 2gb)
1) format flash drive in FAT only (pay attention only that drive)
2) extract and run wincrisis file (locate folder when done)
3) extract and run bios update, DO NOT! install, exit when window appears, locate folder
4) place files in formatted FAT prepared bootable flash drive: minidos.sys, philash16.exe, bios.wph
*NOTE* You will need to rename the bios.rom or any label bios file to bios.wph using the one found from extracted PC vendor supplied update only. Your PC maker may want the bios.rom label, follow its instructions. Mine from Dell wanted the bios.wph file in using the wincrisis method.
5) remove laptop battery
6) install ext. flash drive to USB port
7) press Win key + B key -or- Fn + B -or- Fn + F -or- Shift key alone, plug-in AC adapter, try all steps because it varys from PC maker or bios version currently installed!!!
power led should flash orange/red momentarily once, release key(s) and press power button
Hopelly, it should appear to run as fan, no display or LEDs flashing but power LED is ON. Allow 10-20 min. for bios update to take place. once done, it should reboot and then act correctly now being updated. If no reboot then simply allow the full 20 min. before attempting a manual reboot or power-OFF, then power-ON. You can remount your battery if A-OK.
*NOTE* If you made a bootable USB flash drive it may have the added files flash32 and/or flash64 or add if not found. Do this if the bios update didn't work or froze but follow above steps first. To find any of the above files, google to find a trusted web source and d/l. Other similar searches using your "laptop model and failed bios update" as keywords will produce results. Upon if any of the above key combo, like Win + B doesn't work try the
other combo but you may need to disconnect the AC adapter(1-2 min.) to discharge capacitors, then try next combo. In my case, Shift key alone worked.
1) Format ext. USB flash drive in FAT only(I used windows own format, flash drive is empty/blank)
2) extract PC maker latest bios update, rename bios.rom to bios.wph
3) Run wincrisis, will create its folder, delete bios.rom and place bios.wph from PC maker there
4) Run wincrisis app. and with bios.wph present will create a bootable flash drive
5) Verify bios.wph, philash16.exe, minidos.sys present
6) mount USB flash drive and have laptop battery removed
7) Press Win key + B key -or- Fn + B -or- Fn + F -or- Shift key alone, plug-in AC adapter, LED should flash, release key(s) and press power-ON if not already
Allow 10-20min. for bios update process, once done it should reboot, if not allow a full 20min. then manually reboot or power-OFF then power-ON
9) if successful, laptop will return to normal with updated bios.
