M14x R1 - BIOS A08 with SATA fix

Recommended Posts

Two new modified BIOS for M14x R1 users. Both based on A08, but with the same SATA performance as in A05.

This allows GF106 users which are still on A05 to benefit from the fixes included in A08 while keeping the SATA performance of A05 and it allows GF116 users to get the benefits of A05 SATA behavior.


It's actually the result of trying to bring GF116 support to A05 in order to change the SATA behavior (as requested by he_yincheng), since this didn't work as planned I tried it the other way around - bringing the SATA performance of A05 to A08, which succeeded. Thanks @he_yincheng for testing! Check here to see some screenshots he posted to verify that it is working as intended.


There are two versions of this mod available, one is the standard A08 with only the SATA tweak and the other is the unlocked version of it.
In the M14x R1 voltage mod thread you can also find both versions with an increased GPU voltage, GF106 and GF116 supported.


As always with such mods, use at your own risk, I don't take any responsibility for possible issues. 
You are responsible for the changes you make on your system.


Feedback is welcome!

It's doest work. System started only after many attempts and freezed after 2-3 min of work. It's enough for re-flash original BIOS...

Please can somebody provide/PM me the link for this bios download? At my wits end with my 5 year old m14x r1 just want to get it sorted now and the A08 unlocked bios seems to be the last piece of the puzzle!

Bump this post. If the the original download link is dead. Need it. Can't tell because I'm still banned or not allowed to download because my account is new and unfortunately this is the only place you can download it.

This appears to be exactly what I need to disable Nvidia Optimus and allow Windows 10 to see the dedicated graphics card.

Going to be getting an 850 Pro to put into my m14x and giving this BIOS a try. I will report back with results.

Hi All, new here and just replaced my HDD with Samsung 850, but am not able to download the fix due to pre-promotion.

Aside from installing and tweaking configs as guided by google, I really am not familiar with the terms, so can anyone help out a helpless soul for below queries?

 

-how will I know if am actually R1 or R2?

-how will I know if am A08 or A05?

-what does unlocked A08 mean? what do we intend to accomplish from unlocking a bios?

-what does overclock mean? Why do this?

-does anyone know how to selectively have the fan run and not? I just want it to run (and yea its fan noise on and off) only when I play Dota2

-And how do you exactly measure 6gb/s speed?

 

Appreciate anyone teaching a "kid" the basics.

not sure if you're still checking here, but you can see in the BIOS for R1 or R2 versions.. it will say right on the main screen.  The same goes for A08 or A05 version.

 

the unlocked versions will reveal hidden areas that the OEM has blocked from our view for possible access... doesn't mean everything will work though as the OEM has to also supporting code/hardware for those features.  but unlocked gives us access to look and set properties.

 

instead of modding the BIOS to control fan speed you should look to software for controlling that such has OpenHardwareMonitor or FanSpeed.. both work very well for controlling this capabiltiy.

 

for measuring HD/SSD speeds, you can use a tool such as ATTO Disk Benchmark to run tests against the drive to see the actual speed (it will nearly never fully reach 6gb/s in real world)

well.. it looks like I won't be getting this anytime soon as i found a version by svl7 and was impatient... while the unlock worked, i screwed up trying different PEG mode settings and caked things up good.  :(

 

atleast for a while I was close.. had EFI/UEFI booting with Clover and nearly had climbed sierra, but couldn't get past the discreet video stuff and wasn't satisfied with only HD3000 working...

 

oh well... now the thing just recycles on boot.. tried everything imaginable to clear it and the best I could get is 2 beeps after removing the RAM  (could never get the lovely 5 beeps to acknowledge CMOS was alive again).  :(  sad pandas.

ok, i was able to get something using a CH341A programmer and flashrom.

 

does anyone happen to have a dump of the EC for this system?  I got a couple readings, but now I'm unable to read it using a SOP clip.  I would like to do a bin compare to see if the first few readings I got are actually accurate.

heh, yes... this thread is super old and i'm probably just posting to myself but that's ok lol.

 

so, i found something interesting.  the CH341a programmer I purchased has a AMS1117 voltage regulator on it... which was getting really hot when I was trying to read the W25Q80BVSIG... like really hot to the touch.  Flashrom would either not see the SOP at all.. or just throw a bunch of read errors.

 

So I put a vortex fan on it (small household fan that blows really well)... and now I have no issues reading, write/verify the chip.  very very odd.  i'm not an electronics engineer or anything, but I know when something is getting way to hot. :)

 

I also discovered (as I have two of these boards for m14xr1) that the EC chip holds data for the LED programming... yep.  The original board would light up blue on the keyboard, and the new board i got lights it up white.. well, after moving the new boards EC data to the old board.. now it also lights up white :D  interesting...

 

I still having troubles reading the BIOS on the old board... no issue with the new one.  Perhaps it is dead.  I'm waiting for my Hakko soldering iron to come in tomorrow and am going to just remove it and try again.

 

I'm a total noob to this btw.

this was an interesting find on hackernews: (post by mjg59 way down the list)

 

https://news.ycombinator.com/item?id=11863719

 

apparently, supplying enough power to read the SPI chip (SOP?) with the chip still onboard can sometimes generate 'connected' traffic from other components... and may lead to fail reads.

 

i didn't know this could happen.. probably why i keep failing to read that BIOS.  looking forward to being able to pull it.

 

is there any problem with desoldering/resoldering too many times?

ok, got the solder iron today..  desoldered BIOS (chip U48) and was able to 100% reflash with no issues.

 

just a note for anyone else whom resurrects this in the future.  the FD files you get from either ASUS or here will need to have their header data removed for use with the CH341a programmer.  The header is ~128KB in size (the files are around 4224KB and need to only be 4096KB).

 

I also choose to use Linux Mint with the Flashrom open source program (flashrom.org) and it worked spectacularly.

 

thanks! and much appreciate the information found here.. once i get more $ in my paypal, i'll donate as i have done for tonymacx86.

How did you remove the header?  I'm having the same problem with a bad bios that you did, but I'm using an SPI programmer with a clip instead.

      Hello everyone! I am looking for an answer to a problem I cannot find a solution to ... I purchased an Amd wx 4150 MXM GPU module su e bay to upgrade my HP 8570W Mobile Workstation which is currently equipped with a Fire Pro M4000. Once the new GPU has been installed, the PC screen no longer turns on but works only with external monitors connected via the docking station. The same happens once the drivers are updated! If I put the old card back on, the integrated monitor starts working again ... How can I fix it?

      Bios Release Version – v2.0.0
       

       
      Updated or Modded Items:
      A11 UNLOCKED BIOS FOR m18Xr2 (UNLOCKED BY SVL7 AND FULL CREDIT GOES TO HIM FOR UNLOCKING!)
      SVL7 Also created the PRR2.EXE tool that allows you to flash the new bios by unlocking it.  (FULL CREDIT GOES TO HIM FOR THAT FILE PRR2.EXE)
       
      Here are ALL the things I've added, modded, and enhanced on this bios -
      I've added FULL LEGACY SUPPORT ON THIS BIOS with ONE or TWO CARDS (SLI).  You can FINALLY use Win 7 OS on your machine and run the 900 series GPU's! 
      This is a MAJOR breakthrough!
       
      LEGACY SUPPORT Confirmed.  Works with 900 series GPu's in single OR SLI formation Updated the Intel RST Legacy to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated Intel RST UEFI to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated the ONBOARD Video Card for the HD3xxx to v2171 - FROM v2132 Updated ONBOARD Video Card for the HD4xxx to v2171 - FROM v2132 Updated the LAN Firmware & PXE Boot from 2.0.5.9 to v2.0.6.6 ADDED NvMe Support for m18xr2 ADDED M.2 support for m18xr2 Updated CPU Microcode to v29 for the 2900 CPU's Updated CPU Microcode to v1c for the 3900 CPU's Updated GOP Driver for Intel Sandy Bridge CPU Updated GOP Driver for Intel Ivy Bridge CPU Updated MAIN GOP Policy module for the m18xR2 Eliminated some code that wasn't used in the m18xR2 Updated CSM Module (v2) Streamline some coding to make mod(s) run a little more efficiently (v2) Added FPARTS.TXT to rar file in v2. (I had forgot to add it in v1) v2.5 to be released shortly.  I've updated a few more modules that I didn't realize could be updated.  (It's only 3 modules, but it's still an update!)   It should be released in about a week.  Hope this helps ya'll!  
      Instructions to flash:
      Use a flash drive to create a boot disk into dos Unzip ALL files into the root of the flash drive (flash.bat, r2final.bin, fpt.exe, flash.bat, prr2.exe, fparts.txt,m18r2.hdr, m18r2.hdr.bin, readmefirst.txt) BOOT INTO DOS – Note, that when you set the bios to legacy in order to boot into dos, you MAY have to reinstall OS!  (Just be prepared to reinstall no matter what) Once you boot into dos, run the file flash.bat It will unlock your bios (THANKS TO SVL7’s BIOS UNLOCKING TOOL – ALL CREDIT TO HIM FOR THIS TOOL!) Let it flash… Reboot your pc, and enjoy the MASSIVE updates!  
      Be on the lookout as I do plan to release newer version with more updates in the future.  However, it wont be for at least a few weeks as I'm now working on legacy support for the m17xR4 and several other systems.  So please be patient!
       
      ENJOY!

      I have a iBuypower CZ-17 laptop, with a 2012 AMI BIOS that has E1762 as the version, which I believe means I have an MSI G70 motherboard. It has a 675MX GPU, but it's not useable in Windows 10 despite being "seen" in the device manager. I believe an updated, unlocked BIOS would fix my issue and have located the thread on this site with the BIOS I need.

      First of all, am I right? Will this fresh BIOS make my laptop that originally ran Windows 8 work with this old GPU?

      And second, I created this account, will wait 24 hours and made this post. Is that enough to allow me to download the file, or do I need to post elsewhere?

      Thanks!

      A part of my BIOS got corrupted that controls my laptops backlights. Other methods like the Gary Key fix did not work for me because I do not get any light up during post. i followed this guide  that says I need to extract and use the 6MB portion of an 8MB bios dump, only AFUWIN tells me "Error, ROM file size does not match existing BIOS size which is because my laptop BIOS size is only 5.87MB.  I don't need to flash the whole BIOS, I only need to flash a portion of it. 
       
      I've searched everywhere online for a dump of my laptop model but non exist that I know of.
