Fixing BIOS Damage

NOTE:
- Download the correct .exe installer from Dell's FTP site or Driver Site (Click on BIOS download->Other versions for older)
- Download Universal Extrator and install
- Run the first part of the Dell BIOS installer. It will extract 1645_AXX.exe, where XX is the bios revision, to a folder of your choice and open that folder.
- Right click on 1645_AXX.exe, and click on UniExtract to SubDir. Click on "Not an Installshield installer"
- It will open up your dos box and extract everything to a sub directory
- Navigate to 1645_AXX/.rsrc/1024/RCDATA/ and find the 5meg file, in the example case of 1645 bios A09, it's named 7000 with no file extension and weighs in at 5182 kb
* If the folder structure is different, then look around until you find any 4-6 meg file, that's the bios file.
- Rename it to BIOS.WPH and put this into your Crisis BIOS Recovery folder to replace the existing BIOS.WPH
- Run the BIOS Recovery tools as mentioned earlier in this thread. Success!

Another thing to note, if the recovery tools don't work for you by just plugging in the A/C and turning it on, take the battery out, stick in the USB to your USB/eSATA dual port, hold the END key, after 3 seconds plug in the A/C and release the END key. It should automatically turn on and use your usb stick to recover the bios. The circles on each side of the laptop will be orange if it's working. When it reboots after 2-3 minutes, take out the USB, let it boot to windows, shutdown, remove A/C, put in your battery, put in A/C, and boot up again and check your BIOS to see if the version is correct.

The only thing I'm not sure of is if this method actually flashes everything that needs to be flashed. I'm in no way a low level hardware guy. Is flashing the system BIOS the only thing Dell's installer does? I noticed the Dell update A09 notes say it updates a few other things, such as updating the SPI ROM EN25F32(BIOS) and the EN25F80(EC), but is that all inclusive in one simple BIOS.wph? I noticed there is a 1 meg file in the RCDATA folder, which is why I ask.
step to recovery bios:
step 1:create usb flash(download and run the WINCRIS.exe, and click "start")
step 2:remove the battery and unplug the power cable
step 3: plug in your usb into your laptop
step 4(important):hold down the key "End" in about 3 seconds and then plug the power cable at the same time release the key "End".
step 5: if you see the battery light is on with red, wait a few minute ...
If laptop is restart automatically, it means that the recovery is successful.
