ALIENWARE AURORA ALX  LGA1366 MOTHERBOARD 4VWF2 MS-7591

The Aurora R1 was based on the Intel's X58 platform (LGA 1366 Socket). It shared identical hardware with the Aurora ALX R1. Processors included Core i7  920, 930, 940, 950, 960, 965, 975 , 980X , 990X . Sealed liquid cooling units for the processors came factory installed. The X58 platform can use Intel Xeon Processors, but none were used in the Aurora. The R1 used triple channel Memory and had Dedicated Graphics Card options from AMD's HD 5000 series line as well as Nvidia GeForce 400 Series and Nvidia GeForce 500 Series line. Power Supply options included a 525 watt Power Supply Unit, 875 watt Power Supply Unit and a 1000W Power Supply Unit. Power Supply and Motherboard supports both SLI and CrossfireX.  I'm thinking its similar to the T3500 but not the same board maker. Having the LGA 1366 socket means that certain Xeon processors will fit, but they may not be supported by the Bios.

Many thanks for the information, I could not find these BIOS firmware.

These BIOS firmware can be installed in series?

Try the last one.  If you need an earlier version they will say. If you are at A01 it may require A08 before jumping to A11 for example but this is not a one size fits all it depends.   Easiest thing to do is try the last one first if it needs the older it will tell you.

(REMOVE ANY ANTIVIRUS SOFTWARE BEFORE Trying ANY of the bios.)
They must be Right Click Run as Administrator.

Approximately understood, thanks a lot for the answer)

I asked Bios, the computer rebooted and gives out Cheking NVRAM. Tried to reset BIOS settings (battery and jumper), disconnected everything from the motherboard, left for a while, does not help. What now?

Changing CPU before Bios Update with XP or Windows 7 is not recommended.

Turning off before bios update is complete Bricks the board.

Bios updates can take a VERY LONG Time and impatient people kill boards by shutting off.

This is why antivirus software must be REMOVED before trying.   Disabling in software DOES NOT mean removed.

You have to DEINSTALL the software and have BARE WINDOWS.

 Disconnect everything and remove all cards.

Remove battery.

Disconnect ALL CABLES

Hold power button to discharge.

Attach only power cable and video cable and keyboard.

Turn back on.

Should be POST errors.

The other way to go would be to migrate to a Precision T3500

Nothing helps, I'll give it to a repair shop.

Error: CMOS Checksum Bad

In the technical support of DELL will not help, they have nowhere to write, an incomprehensible use of the site.

Tell me how to extract the BIOS from EXE. file. You need to reinstall the BIOS programmer.
