[8460p] How to change BIOS for older version

Recommended Posts

Hi guys,

 

At the first, sorry for my language. My english isn't very good.

 

I have a problem with my HP EliteBook 8460p. I bought a SSD drive for my laptop then i got info that my BIOS F60. is blocking SATA 3 option so i got only SATA 2.

I found info on google that older BIOS F20. is still with SATA 3 config so i'm trying to install it but with no effects.

 

Of course i've tried to install it from Windows ( HPQFlash ) but program says that is older BIOS so i can't change it.

 

Then i've:

-install "HP BIOS Update UEFI" and "HP System Diagnostic UEFI"  on my pendrive,

-put BIOS file ( 68SCF.bin ) in Hewlett-Packard/BIOS/New with .sig file ( signature file for BIOS file )

-restart my laptop, pressed F2 for "HP Advanced Diagnostic"

-choose "BIOS Managment"

-select install New BIOS

-UEFI found 68SCF.bin in /New folder

-but then i've got error says "The System BIOS update failed", "Signature of BIOS image failed verification"

 

So there is a problem with .sig file of course. I try all .sig files that i have. No one of them worked. I try to change names of .sig files for "69SCF.sig" but without effects. Still no verification

 

Any ideas?

Only change of doing it is getting a F.20 8460P bios dump using fptw64  (Intel Flash Utility) and flashing it to your system. Required is unlocking the flash descriptor which accomplished by holding WIN+LEFT ARROW+RIGHT ARROW key pressing power on button.

 

8460P BIOS dump can be found at http://forum.hpfocus.com/viewtopic.php?style=51&f=2&t=2475

fptw is contained in https://github.com/LongSoft/FTK/releases/tag/0.12.0

 

HP have otherwise prevented downgrading BIOS as you've found using their tools.

Thanks for answer! One more thing, can U reupload 68SCF8.zip file from hpfocus? They want me to get 50 points in their forum, i don't want to make ridiculous new threads on their forum just to get points.

I don't have 50 points to get 68SCF8.zip with nor own a 8460P to grab a dump from.

Can i bios dump from my 8460p and share with some software?

 

68SCF is indeed 8460p Bios at least for mine, and i can confirm that a Sandisk Extreme Pro 240GB Model does run with sata 6 according to its own tool.

 

@TBlazer: Maybe you can find the hp spXXX.exe and extract something that is flashable? ftp://ftp.hp.com/pub/softpaq/sp62501-63000/sp62738.html says it is F42 inside sp62738.exe

 

Ok downloaded it its too big for this forum aww shwt well here you go:

Guys, I don't know anything right now. All program says that drive is working on SATA3 mode. Is it truth? I found test of my BX100 250GB SSD on web here os comparison with my results. Should i change the BIOS?

 

In SANDRA screen: G3 is SSD i think and G2 port is for my WD 750GB SATA II HDD in multibay

Your SSD is getting just under 500MB/s read speed on your 8460P with F.60 BIOS. That is definitely at SATA-III link interface speed as explained at http://kb.sandisk.com/app/answers/detail/a_id/8142/~/difference-between-sata-i,-sata-ii-and-sata-iii below. So no need to change your BIOS.

 

Difference between SATA I, SATA II and SATA III
 
What is the difference between SATA I, SATA II and SATA III?
 

SATA I (revision 1.x) interface, formally known as SATA 1.5Gb/s, is the first generation SATA interface running at 1.5 Gb/s. The bandwidth throughput, which is supported by the interface, is up to 150MB/s.

SATA II
(revision 2.x) interface, formally known as SATA 3Gb/s, is a second generation SATA interface running at 3.0 Gb/s. The bandwidth throughput, which is supported by the interface, is up to 300MB/s.

SATA III (revision 3.x) interface, formally known as SATA 6Gb/s, is a third generation SATA interface running at 6.0Gb/s. The bandwidth throughput, which is supported by the interface, is up to 600MB/s. This interface is backwards compatible with SATA 3 Gb/s interface.

SATA II specifications provide backward compatibility to function on SATA I ports. SATA III specifications provide backward compatibility to function on SATA I and SATA II ports. However, the maximum speed of the drive will be slower due to the lower speed limitations of the port.

 

Example: SanDisk Extreme SSD, which supports SATA 6Gb/s interface and when connected to SATA 6Gb/s port, can reach up to 550/520MB/s sequential read and sequential write speed rates respectively. However, when the drive is connected to SATA 3 Gb/s port, it can reach up to 285/275MB/s sequential read and sequential write speed rates respectively.

Well for SSD's i don't really know but transferspeeds are not that important..... they are usually fast enought its more about iops :-P

Doesn't look too bad for a used and filled ssd to the rim, if you leave some more space it runs on cocaine ( nCache runs flash cells as slc does some funny caching )

I can see on my own screen shot that i had 40Gb+ free thats no more, dang i need to delete some games.

 

The last time i checked your ssd type BX100 was Bargain/economy class and with these numbers i would be more statisfied, it destroys any hdd thats more than enought.....

For my experienece i have to say that my Samsung 840 Pro 256GB feels fast at work (Z77 corei5, Sata 6 on an Asrock board), but the sandisk is faster but not if you fill it hard  to the rim.

 

I am sure theres a tool for your BX100 to maintain firmware and health that should tell the right link speed read from the ssd itself.

 

@Tech Inferno Fan When i ran the bench, "sandisk ssd dashboard" complained not to run benchmarks with windows drive caching turned on and that it doesn't like the current benchmark software and will turn off some of its boost features :-P

      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.
