Hey Everyone,


I'm looking for some testers to see if we can get LEGACY SUPPORT for the m17xR4.  

Furthermore, I've also done MANY updates on this bios, too...  


I updated RAID (EFI & LEGACY) to v12.9.0.2006 (This may need to be downgraded as the chipset you have may NOT support this raid version, but this is the latest version that will work IF youre running RAID.  It also supports TRIM in RAID0.  If you are not running raid, I can update to v13 if you want, but we need to test one at a time!)

Updated GOP Drivers & GOP Policy

Updated vbios from 2098 to 2171

Updated Microcode for all cpu's

Added M.2 Support

Added NvMe support

Updated Atheros Lan Firmware & PXE Boot Firmware

Updated To Possibly Give Legacy Support, BUT.......




Please contact me if you want to try.  Understand, HOWEVER, that  am NOT responsible for ANYTHING that happens to your system if it goes wrong.

(Just a SMALL disclaimer, heh)

Hello, can I test your mod bios for m17x R4.

I'd be very glad to be a tester.

Thank you,

If this project is not dead @Swick1981 I can help testing - have a spare M17x R4, GTX 970m and eeprom programmer so can easily recover from any bad flashes :-)


Kind Regards,

      i want to ask two favours and a question from this community ..
      1.) Can someone mod my 940 mx to increase the target temperature and allow higher overclocking than 135hzband voltage control
      2.) Allowing my i5 7200U to be undervolted to reduce overall heat 
      The question : I repasted my gpu and cpu cleaned it thoroughly, made sure twice everything is connected properly, use a cooling pad and yet the upper portion of my chasis above f1-f12 keys is so hot that i can roast peanuts on it. 
      (if i left out any info or missed something please reply i would really love to have a page that has everything for people who have this laptop specifically for light gaming.)

      So I just received a 980m in the post and after installing it I was greeted by multiple system crashes on my Alienware m17xr4 and was unable to install new drivers.

      Is there a step in the intallation process I missed? A bios setting I was supposed to change? The laptop is already set to UEFI mode in preperation for this and upon putting the old 680m back in the system it now works again. I have heard that I need to change INI files to install drivers but I expected it to at least function without large bugs such as these. Do you think that this GPU is faulty or have I done something wrong?
      Thanks for any help you can give.
      - M
