I just cant download it... ://

Dell has hidden a lot of options in the BIOS of the Alienware M17x R4, the modified BIOS versions here will show you all the hidden menus and allow you to further tweak your system and optimize its performance.

Don't change anything you're not familiar with. There might be functions available which don't work on your system, so use this BIOS with care. It should only be used by advanced users.

In case you mess up and your system refuses to boot after applying the changes you make, remove the AC adapter, battery and coin cell battery in order to clear the non-volatile ram of the BIOS. This should fix most issues.

***********************

Instructions:

If you're on A05 or an earlier version, you can flash the modified bios by simply using the InsydeFlash utility provided with the official bios update on the Dell support site.

However, once you're on a version newer than A05, things get a bit more complicated. There are two options then:

- Method 1:

Revert to stock A05 or earlier by using the Insyde USB bios recovery method, and then flash the modified bios by using the official tools (InsydeFlash).

- Method 2 (recommended):

Flash the modified Bios from DOS by using the FPT tool:

NOTE: The flashing from DOS as described above will only update the BIOS, not the rest of the firmware. Therefore I strongly advise you to first flash the stock version of the bios you want by using the official update provided by Dell, and once that's done you can go ahead and flash the modified version of your bios by following the instructions above.

It's hard to find users who are willing to risk their system in order to test a mod, I greatly appreciate this! Thank you!!
