Ok so I need access to the advanced options in my BIOS on a TOSHIBA Satellite C850-B561 from 2012, I need access to it in order to increase my Intel Integrated Graphic's dedicated VRAM or its minimum shared system memory. Now, I've tried numerous methods to unlock these options such as pressing A just after pressing the F2(BIOS key) on my keyboard or pressing FN+TAB 3 times on the keyboard. So I've come to my last resort of hoping that someone who reads this will make a modded BIOS for me as I have no idea on editing my BIOS, My BIOS is an InsydeH20 v6.80 rev 3.7 and on the BIOS main section it says all this,
System Time:
System Date:
CPU Type
CPU Speed
HDD/SSD
ODD
Total Memory Size
System BIOS Version: 6.80
EC Version: 6.00
Language

Now I need access to some more options on the advanced section, On the advanced section I only have all of these,
Boot Speed: Normal
Execute-Disable Bit Capability: Available
Virtualization Technology: VT-x Only
Beep Sound: On
USB Power in Sleep Mode: Enabled
USB Legacy Emulation: Enabled
>System Configuration

Now inside of the System configuration section, I don't have what I'm looking for. Please help me out, I don't have any other options available. I have experience with software and Hardware, Mostly with Hardware but never with the BIOS, Please try to unlock other hidden menus and options as well ^_^

Greetings everyone!

I have a couple of issues with this model, which I have seen addressed here through the past years that I have been using it.

My first issue would be the innate lock of the HM70 southbridge, which shuts the computer down after exactly 30' if the CPU is detected not to be matching the HM70's "list". Through my research towards this issue's solution, I came across the ME's 30' shutdown restriction, which seems similar to what I am facing. I first got some hints of this from this post: https://www.bios-mods.com/forum/Thread-U...processors, in case anyone is furtherly interested or facing the same issue. I haven't twinkled with MEcleaner yet, as I'm waiting for my flasher to arrive, but I have not many hopes for this issue to be solved, as I found out through a little more digging that ME's 30' restriction is irrelevant to HM70's 30' restriction. Once my flasher arrives I will attempt it either way, in case it miraculously decides to accepts my i5-3320M. Otherwise I will have to stick with the Pentium B960 that the machine came with.
This concludes the first issue and I'm writing this just in case anyone has any idea or advice that could potentially solve this issue.

The second issue concerns a BIOS mod or, if even possible, an upgrade. It regards the same machine, a Toshiba Satellite C850, which has been running on the latest official BIOS since the day it was purchased. This was approx. back in 2014, so, as expected, its battery has run out of juice by now... I recently bought an OEM new one, and, as if this machine is unwilling to accept anything that is fed to it, it isn't recognizing it. Instead, there is the battery LED blinking at a steady pace, even when the laptop is shut down. Also, the laptop will not be starting with this new battery plugged in.
I got around this issue by removing the battery, starting up the computer and then plugging it in, when it "recognizes" it and posts it at 100%. (I believe this is just the last-known condition of the old battery.)
This solves my problem short-term and allows me to flash a new BIOS as well, as the computer is tricked to think that it has a full battery, but I'd rather that I don't have to unplug and plug the battery every time I want to turn the computer on. (Also, if I remove the power cable, it will revert to the "LED blinking state", so it will shut down almost immediately.)
Through this post (https://www.ifixit.com/Answers/View/5750...+installed) I found out that it is a BIOS issue yet again! The easiest solution is simply a BIOS update, yet, I happen to already be running on the latest official BIOS for this device... Here lies my question: Is there a mod, an unofficial BIOS version or even a revision anywhere?

I have upgraded this laptop's HDD to an SSD, adding a disk caddie in the process to host the spare HDD, its RAM from 4GB to 16GB (somehow that was accepted) and am looking forward to its CPU upgrade as well (I bought the i5 nearly a year ago)... With a new battery and all these upgrades, I see it running a couple of years more (at least until win10 are abandoned, or potentially even further).
Therefore, any help regarding the above two BIOS related issues will be much appreciated!

Hello!

I have been following both the post where donovan6000 created these mods (https://www.bios-mods.com/forum/Thread-R...-Flash-Mod) and this one, as I have posted a thread myself about my issue.

In case donovan6000's mods help me with my problem, is there anyone who can reupload the bios files for version 6.80? The download links (for instance: https://www.sendspace.com/file/cg7hbc) do not seem to be working for me...

Thanks in advance!!

I have the same problem as everyone here wanting to upgrade the cpu on hm70 chipset with no luck... this 30 min sleep timer was the main problem. I managed to flash unlocked bios from here in hope that it will fix the problem, but still nothing so i reverted to original bios.

Last night i was searching for the possible solution, and i found out that some guy from Poland managed to make it work by swaping ME region with hm65 chipset based "donor" and then applying me_cleaner make the i5 cpu work with no restrictions. So this is what he wrote :

"Hello,
It's been a while, but I'll share my experiences here on this topic.
I have laptop ASUS X401A-WX095V (intel HM70 chipset) - originally came with Celeron B820. 2 weeks ago I swapped CPU to i5-2410M (from Toshiba Satellite Pro C660 on HM65 chipset) and like other Users every 30 min laptop suddenly turned off. But...

Yesterday I found a solution (for me and my x401a) which is as follows:

Dumped BIOS from EEPROM using external programmer (I using latest BIOS for this laptop ver 212), no need to desolder,
Next used Hex editor for downgrade ME Region to 7.0.4.1197. I used stock/clean ME Region 7.0.4.1197 for this downgrade purpose,
I flashed back new modded BIOS with new ME Region,
..and after that, laptop was able to turned on, enter to BIOS, but couldn't boot from any connected media drive (sata, usb)..., so I applied Linux version of "corna / me_cleaner " from github.
So last step was:
I runed "me_cleaner.py -S" script on my new modded BIOS with downgraded ME Region 7.0.4 (in my case works first suggested option with capital S from me_cleaner instruction) and again flashed back second modded bios.
Thats it!!
After that my laptop is able to boot from any media drive and working without 30 min shutdown!

note:
-my Asus X401A on HM70 had original BIOS v212 with ME Region 8.0.10.1464
-donor Toshiba C660 on HM65 had BIOS v1.50 with ME Region 7.0.4.1197

Maybe this will help those who are still looking for a solution. Hope it does

Best regards from Poland!"

Here is the link if someone wants to check this out, a few other guys confirmed this worked: https://github.com/corna/me_cleaner/issues/186

So my problem is that in the downloaded exe file from dynabook site there are two files when i extract with 7zip, one named F8_ME_FW.FD other one named F8680.FD i assume by the name that the one with "ME" in file name should be edited... Can someone please help me with this? I would be very greatful!
