Acer Laptop with Phoenix BIOS: BIOS MOD Request

Sure. I'll take a look later. I'll update here when it's done.

 

I know what I did wrong.

Because of I changed the voltage manually, the last byte (which is the checksum) was not modified.

This caused the VBIOS being detected as bad while it was actually correct.

I changed my things in NiBiTor like you said. And then resaved it. And I noticed the last byte was A4 instead of 9F.

 

Hi, kizwan
i want to ask if this values is true in bios

passive cooling trip point = 95
passive tc1 value = 0
passive tc2 value = 2
passive tsp value = 10
critical trip point = por
high fan trip point = 39
activetrip point = 39

dts smm = critical temp reportting

then i want to know enable or disable this values
CX states
Enhanced C-states
PAVP

thank you very much
i'm sorry i am disturb you

 

If running on a laptop I suggest keeping Enhanced C-States, CX States etc enabled. They prevent overheating of the cpu or advanced power saving. Google for the possible C-states. But I suggest keeping them enabled.

I suggest setting the active fan trip point around 40-50C and the high trip point around 60-70C, like it was on my dell studio 1558. You really dont want a high fan trip point on such a low temp.

 

A word of warning, apparently running wincris.exe under 64bit Windows is bad.

As in 'replaced my RAID 0's MBR' bad.

*sigh*

 

That what happen when you didn't follow the procedure carefully.

 

I was under the impression that wincris usually does not work under 64bit Windows (I tried it once, it didn't work, and then I ran in under a 32-bit XP VM and it created the USB disk succesfully).

It seems that the first run caused damage, which became apparent on the next reboot

 

The modified BIOS image for Clevo W860CU, based on BIOS " 10012GH_EC10_XMG7C (For W860CU)" is available at post #1596. Use at your own risk!

Please take picture of the unlocked menu/sub-menu. I want to make sure all are visible & accessible.

 

Hi Kizwan

I have a Acer Aspire 7741ZG (notice the ZG)

Iv been looking for well about weeks for a cure for my i7 (heat problems)
Please PLEASE i need a modified bios for this so it unlocks the 'Intel Menu"

I see that youv done the (older) versions of this series the 7741z and the 7741g

heres a link for the bios on the Acer website.

Thanks in advance man!

Or select it yourself from the top :

Acer Support: Downloads & Support Documents - Notebook / Aspire / Aspire
7741ZG


Its pretty much the same bios as the older ones - but its a diferent Vbios (video card)

 

Hi,

First of all Aspire 7741 series notebooks (Aspire 7741ZG, Aspire 7741Z, Aspire 7741G & Aspire 7741) use the same BIOS. You can download & compare each of them.

Aspire 7741 vs. Aspire 7741G


Aspire 7741Z vs. Aspire 7741G


Aspire 7741ZG vs. Aspire 7741G


Second of all, modified BIOS won't fixed overheating. To fixed overheating, you need to re-apply thermal paste & clean the air vent from dust. For thermal paste, use Shin-Etsu thermal compound. Any Shin-Etsu thermal compound will do. I use Shin-Etsu G751 on my notebook & this what I get. The MAX temp is what I got when running 3dMark06. When playing games the highest temp are around the same range too. The MIN temp are the idle temp.

 

Arctic MX-2 and MX-4 are pretty good choices too (especially in countries where Shin-Etsu is not available). Though I heard the MX series is actually OEMed by Shin-Etsu.

EDIT: See the new 9920G MXM-fixed VBIOS in the x920G vs. 9600M GT thread for a new way of unlocking hidden menus. Basically, it's possible to craft an entirely new top-level menu at the end of TEMPLATE00.ROM, and redirect the top-level menu pointer to it, to get the hidden menus display where they should.

 

I use MX-4 for a couple of months. They perform very poorly. I wouldn't recommend them. Go here to see comparison between MX-4 & Shin-Etsu.

EDIT: Thanks for the tip on the unlocking hidden menus. I'll take a look later. I try to prevent using PBE, that's why I didn't maintain the black splash screen (with Acer logo) for Aspire 5920G on newer modded BIOS. I might be able to reintegrate the LOGO*.BIN module into newer modded BIOS. I don't remember whether I have tried it or not though.

EDIT 2: I just examined your Aspire 9920G BIOS mod earlier - good job on the mod .NetRolller. I noticed the pointer to top-level menu but never use it. One thing that got my attention is the new "Generic Text" menu you created for AMT section. That good one. Also it never came to my mind that adding new space at the end of TEMPLAT00.ROM is possible. I'm not using PBE (because half of the BIOS I modded, PBE unable to open them), so might not possible to create top-level menu at the end of TEMPLAT00.ROM but can create at any unused space before $PDW. In some BIOS, for example latest Clevo W860CU BIOS mod, I found some unused table (contain menus) that not linked at all & the menus not important at all (at least not interesting to me). So, I use the space to create two new sub-menus (Processor & Memory) for overclocking. Basically just like you did in Aspire 9920G BIOS by creating new table/sub-menu & create/redirect pointer to it.

 

Hi kizwan! Is there any hope that you can change the voltage (from 1.0 to 1.05) video card at AS5740G? recently the issue has been raised in "Acer Aspire 5740G Owners Lounge".

 

It has been tried & failed on AS5740G. I don't think I can do any different.

 

How is it going? Please let me know how it goes. Please post screenshot of GPU-Z or HWMonitor (while on full load) when you successfully applied the voltage mod.

 

Uh im sorry i forgot to explain the part with overheating

You see i have a intel i740QM (with Turbo Boost enabled) i want to simply disable it - iv run test and stuff and it never ever reaches (and stays stable) (due to heat couse it throttles down) at (or above) 11 multiplier

It simply says - i need more - BOOST - STOP too much - stand down to 9 ~ 11 multiplier (around 1200 mhz) ~ all of this happens in a couple of seconds

So you see - i want to disable turbo boost so it doesnt boost that 1 - 2 seconds to overheat and then knock itsself down to less then 13 multiplier (740qm has 13)

I want it to be stable without the turbo boost kicking in for 2 seconds - then overheating it too much that it knocks down.

If that makes any sense.

also - are you SURE that if i patch with any of your 7741z (or G) it will work

i know 101% that those models have a diferent Vbios.

Only (100% SURE) the ZG model has the ATI Radeon 5650 Vbios
The rest have a diferent video card.

So i dont wanna be a pain in the #$%^ but could you PLEASE be sure ?

 

Thanks, ill flash it next weekend as I dont have a backup computer right now if something should go wrong
Ill put up a screenshot when im done.

 

You can find the modified BIOS image for Aspire 5553G, based on BIOS v1.23 at post #1108. Use at your own risk!

 

As I already explained in my previous post, you need to re-apply thermal paste. Disabling Turbo Boost won't solved overheating. Anyway, you can disabled Turbo Boost using ThrottleStop or set "Maximum processor state" to 99% ( Power Options \ Advanced Settings).

I already explained to you in my previous post. I won't repeat myself. You can download Aspire 7741ZG & Aspire 7741G BIOS from Acer support website, & then compare them yourself.

 

Good evening Kizwan
Can you help me to find where is the explication to flash the bios from dos?
Thank you

 

That must have been counterfeit MX-4. Those temps look worse than the generic white goop bundled with noname fans! G751 is the weakest Shin-Etsu BTW; MX-2 consistently beats it in test. So, either they messed up royally with MX-4 (sure, MX-3 was worse than MX-2, which is why it was only sold for a short time), or it is a Chinese fake. Or it was a measurement fluke (your screenshot also shows a much higher temperature for the HDD, which is not affected by any thermal grease).

About PBE, I use 2.2.1.3. Never had any BIOS that it failed to open, except for Tiano-based UEFIs. (2.2.0.1, on the other hand, craps out on many newer BIOSes.)

 

I bought MX-4 from official/authorize reseller/distributor & I assume they are genuine. I know G751 is the weakest of Shin-Etsu but even though they are the weakest they still able to deliver good job. HDD temp is not related to what thermal compound I use (sometime the temp is high & sometime low - which is out of my control). The comparison was to show the CPU temperature between two compounds. The comparison I made between MX-4 & Shin-Etsu are conclusive in my opinion because I test them with same applications in the same day; read email & browsing websites to check lowest operating temps & running 3dMark06 to get highest operating temps when doing 3D. Probably this is not "industry" standard test but these are standard applications people use daily (check email, browsing & playing games). Anyway, I use MX-4 for months, so no mistake it unable to work good, at least for me. The comparison was to show how two different compounds perform on the same machine. This should help other people with power hungry CPU such as i7 quad core & extreme edition processor.

I use the same version. Please try open Dell Studio 1557 BIOS. You can find the extracted BIOS image here. If you can open it, please share how you do it.

 

You can find simple instruction on how to flash BIOS here.

 

MX-4 works well for me, I went from actic silver 5 to mx-4 and noticed a small decrease under load. (perhaps my ac5 application wasnt very even)
I also use it on my gpu and gpu memory wich works almost the same or even better then the stock thermal pads.

 

Thank you very much, kizwan!

 

Okay it works the bios works

However iv seen some ... wierd things after i flashed

System shuts down like mad

At first it did it while windows was loading
then imediatly after POST

It mighta been something wierd with the CPU overheating (maybe fan didnt switch on)
I cannot check that couse my fan is always on passive when not in windows (not needed)

BTW Crysis method 2 (and 1) doesnt work on this 7741zg (for the records)

So i let it shutdown for like 10 minutes ( i did guess it was overheating)

Then as soon as it POST-ed i did the flash bios thing again and put the original bios in - that didnt fix it.

It did the same thing over and over again.

So - i flashed the midified bios again.

I booted windows in SAFE mode - worked .

Then normal mode worked. all is working

Im thinking it was some sort of error while (due to ... donno) flashing.
(yes default options ware selected on bios at all times)

Or - could it be that windows acts funky after flashing this modified bios (the first time)

And it really shuts down really fast after POST ?

Hence it fixed itself after i ran it in SAFEMODE.

Im just laying this out there for other people incase they got the same thing.

Cheers and thanks alot man.

 

The problem you're experiencing already there before you flash BIOS with the modified BIOS. It just coincidentally became worse. If there is even one error while flashing, your notebook will already bricked by now. The only different between original & modified BIOS is the modified BIOS contain unlocked hidden menus. There is nothing different other than that.

 

uh okay - that mentality works yeah

This changes things

What do you think it can be ?

like off the top of your head ...

Edit :

also you think having it reach 90C on the PCH is a bad idea ?

i mean by disabling HT i can lower the CPU's temp (thus genereting less heat to the PCH) by about 20C (yes really did tests)

CPU with HT on reaches about ... 95c stressed - maybe it passes that , without it reaches 80c - maybe it passes that .

You think i should disable HT ?

I mean all questions point towards - yeah disable it , but lets keep in mind that it doesnt STAY at that temp , i mean it doest (or ever did) load anywhere NEAR 50% (without the stress of course)

But sometimes it does spike for a second or two near 90c


EDIT : (sorry for tl-dr)

uh , i tought that the TZS0 (sensor name) was the PCH - am i rite ?

 

Also you might be right on the thermal paste stuff
I cannot find any Shin-Etsu on the market here (doesnt sell in my country)

What should i get second best from Shin-Etsu ?

 

The TZS0 is a thermal zone sensor. It's not PCH. Thermal zone sensor can be anywhere. It can cover the entire or just a small area of the motherboard. The cooling devices (FAN & CPU) are associated with thermal zone. If thermal zone temperature reaches at certain trip point, it will turn up the FAN speed to reduce the temperature. If thermal zone temperature reaches passive cooling trip point, power consumption of the devices, usually CPU, will be reduced (CPU throttling) to reduce the temperature. If thermal zone temperature reaches critical trip point, system will shutdown. This explain what is happening to your notebook - sudden shutdown.

Unless you're running heavy duty job like rendering, compiling or simulation, 90C is too high. If you're playing games & CPU reaches 90C, that's acceptable too. Disabling HT or Turbo Boost is not a solution. If you still want to disable any of that, I think you should downgrade to i3 instead. i3 don't have Turbo Boost.

 

If Shin-Etsu not available, you can use IC Diamond 7 (ICD7) or Arctic Silver 5 (AS5). I read Coollaboratory Liquid Ultra also good but this compound is electrically conductive, so need to make sure they didn't make contact with anything else other than the CPU heat cap & heatsink. These are among the best compound. BTW, ICD7 need under pressure to work best. I noticed on my notebooks, Dell & Asus, the heatsink on both only put little pressure on the CPU.

 

Please reupload that Dell BIOS to another site (I use ifile.it) - the download page merely reloads if I click the Download button.

 

Can you access sendspace? I already have an account there, so I upload to there instead. Let me know if you still unable to download.

Hi,

I have an Acer Aspire 9920G and I need VT enabled. Can I use the mod bios from this thread. It has the Intel Core 2 duo T7700 which is very similar to the Acer Aspire 9420 which has the T5600.

thanks in advance for you help.
P

 

Hi mullanp2,

Aspire 9920G & Aspire 9420 are not using the same BIOS. So, you can't use Aspire 9420 BIOS on Aspire 9920G. I haven't mod Aspire 9920G BIOS but .NetRolller 3D has. You can find Aspire 9920G modified BIOS at .NetRolller 3D's thread.

 

@Kizwan
thanks for the link. Perfect
also, can I use winphlash.exe in windows to update my bios or should I just use the pen drive boot method with phlash16.
thanks.

 

You can use Winphlash.exe in windows or Phlash16.exe in DOS. I recommend using Phlash16.exe.

 

hi,
When I run phlash16.exe /x /s /mode=3 9920G.wph it stalls at the "Identifying flash memory part type" ?????
Any help appreciated.
thanks
P

 

Try: phlash16.exe /x /s 9920G.wph

 

For the 9920G, I had better luck using WinCris to do regular flashing - Phlash16 tends to fail with all kinds of weird errors.

 

@.NetRolller, did you able to open Dell Studio 1557 BIOS with PBE?

 

It can be opened, yes, though in a weird way. PBE complains about no ROMEXEC, then claims that the BIOS only contains reserved holes. However, the TEMP folder does contain the correct extracted files - apparently this is a pure protected-mode EFI, with no legacy BIOS backend, which confuses PBE.

EDIT: AndyP's tool does manage to extract a ROMEXEC module, and even 16-bit BIOSCODxx modules.

 

Thanks guys. Got my 9920G working:
I renamed the CV120_MXM_V2.WPH (for acer 9920g) to BIOS.WPH and put it in my crisis floppy disk. I connected floppy usb drive and held down fc+esc and powered on.
I now have the Intel menu with the CPU sub menu with VT enabled.
Super!! : )
Thanks,
P

 

PBE can open Dell Studio 1557 BIOS but none of the module is loaded into PBE. I mean I can't emulate or view them through PBE. I should give you Aspire 7740G BIOS instead. PBE failed to open it at all. There are many BIOS like this & sometime I managed to open them after some tweak to the BIOS file but only usable for emulating Setup Table or splash screen.

I'm using andy's tool when extracting & rebuilding BIOS image for all BIOS mod.

 

Unfortunately Andy's tool insists on preserving the layout of modules in the BIOS image - completely unnecessarily. (Oddly enough, I've seen many tutorials on the Net for PBE, which explicitly ask for checking if PBE preserved the layout, under the delusion that a changed layout will brick the machine.)

 

What I like with PBE is the ability to rearrange the modules when necessary. However, PBE also unstable sometime which is the reason why I re-build modified BIOS for three time & compare each one of them just to make sure the build BIOS image is OK.

 

My acer aspire 5535 has a terrible support from acer, only one bios released.
Glad to find here this thread.
If there is there anything it can be done on this bios to make it better when unlocked, please help me out.
Thanks in advance for the help.

Chipset is AMD M780G
Mobile version (M780G, codenamed RS780M/M780V, codenamed RS780MC)
Mine is the RS780M with HD3200 Radeon and Turion Ultra RM-82.
I am curious to ask,
Laptop came with ddr2 800 but in manual states 667 can you make the memory run run at 800mhz, as it already has that speed installed.
Thanks again for any help given.

 

Hi demetris,

I'll try to look in the datasheet what can we do for the memory speed. I'll update here when I have the answer.

EDIT: It is Turion Ultra ZM-82, right? Please post screenshot of AIDA64 (Motherboard \ Chipset \ North Bridge). I need it for my research on your issue.

EDIT 2: Bad news! According to AMD Turion™ 64 X2 Mobile Technology Dual-Core Processor Product Data Sheet, the DDR2 SDRAM controller operating at up to only 333 MHz. This means the highest memory speed is DDR2-667.

 

Hi,
I have sucessfully installed mod bios for acer 9920g and enable VT. But when I install vmware workstation and try to install ESXi as a virtual machine im told that VT in not enabled. I have tried it on 32 & 64 bit OS. I have shutdown a reboot the laptop but still no joy. Just wondering if you know anything about this.
thanks, Peter

 

Just realised that you have to enable the VT setting for the VM itself also.
