Asus G73jh - Bd-prochot - Bios Mod

OK. The BD PROCHOT is 1 thing that seems to work.
But what else? These Fan Trip Points are ignored and always the same on the PM55 platform.

 

Ok, then someone can test it and let us know if it works. All I did was unlock the features that where there by design.

Speed stepping disable works along with USB disable, extra security features etc.

Feel free to play around with the stuff and let me know what works and what doesn't. I have no use for over 90% of the settings that are now visible.

I dont really have anymore time to mess around with the extra features if they work or not. Working night shift and sleeping most of the day. :/


@tilla: You obviously have some know how about this as you have previously dove into the editor and reviewed some of the BIOS files yourself. You know exactly what is in there and what is not. You also know how to save it and flash it and test it yourself. So feel free. http://forum.notebookreview.com/asus-gaming-notebook-forum/631561-ami-bios-editing-tool-g73jh.html


I'm simply making this available for everyone at this point so they can test out the features. Things I have tested work fine for me. *shrug*.

 

Hi, thanks for modded bios.
Bios works fine on my G73. Only problem is that I can't overclock the CPU higher than 1.88Ghz with SetFSB anymore. With original 213 bios I was able to overclock the CPU to 2Ghz.
Maybe I just forgot to set some features that allowed me to overclock it so high .

 

There is NO DIFFERENCE between the the Orginal 213 BIOS and my BIOS. The features are just visible. Please keep in mind when you flash a BIOS, the settings will get set back to defaults (at least they have with my testing).

 

@tilla, so what you are saying is that you modified the Fan Trip points yet the fans still kick on at the previous temp. points? I'd love to use this BIOS if this functionality actually works and isn't dependant on the EC.

 

Would be useful to know for sure.

 

I checked this settings on my X7811. Nothing changed, so I guess it's the same on the G73. But you still can try it.

 

hello I cant seem to download the g74sx bios. what is the MD5 sum?

 

It's in the first post:

Asus G74Sx: Based on BIOS 203

Version 1: G74SxAS.203Moddedv1 - https://docs.google.com/open?id=0Bzj6JjnAJZjjTkt5T1VTMTBGb2M

Everything unlocked!

MD5: ad573c37d369e9880b44987e5e47dbee

Again, I have no way of testing this so it could brick your system.

 

I updated my BIOS to 213, I see no difference in the bios options, is this normal? Will take a picture and post it soon.
What am I suppose to see difference? I have the G73JH Best Buy version.

 

Anyone tested the Asus G53SW: Based on BIOS 203 modded bios yet?
Will this modded bios also work for the G53SW-XN1?

 

NVM it worked great, I bit the bullet and flashed, all options are unhidden.
BD Prochot & speedstepping now work as I wanted them to.
If I need more than a 20x multiplier I can use ThrottleStop to up the multiplier.

Thanks!! so much for this mod, its what I been looking for!!!

BTW saved modded bios to USB stick upgraded the bios with the in bios utility. Flashed without a hitch.

 

Did you update to stock 213 or the Unlocked 213? Unlocked 213 will have a bunch of different options such as Thermal Configuration under Advanced.

I have two G73JHs, both Best Buy (BST7 and RBBX05) - Working fine here.

 

Good to hear!!!

 

Hi,
I have a question about BD Prochot setting. As I understand this setting prevents decrease the multiplier to 12 or lower and it stays on 13 for all four cores?

When I want to overclock CPU to 2Ghz I don't need to overclock the FSB with SetFSB to 166Mhz but just 154Mhz. And that's why my G73jh freezes with this bios when I overclock the CPU. 166*13 is too high for him .

 

BD Prochot prevents multipliers from decreasing when the CPU gets to the temperature its meant to throttle. It doesn't make all cores run at full multiplier, only shuts down the heat protection.

 

Thanks for your time & effort! Super cool...


My G53SW started throttling at 83/85c at 2.6Ghz before & dropped to 798Mhz
with this bios & BD Prochot disabled it no longer throttles.

What I like to see now is if I can change the fan speed to
kick up just a little more RPM at say before hitting 70/75c.
3000/3300 is just not enough, hits 4000 RPM only after going to/past 85C.
I'd like to get it to 3600/4000 by the time its at 68/70c.

Anyone tried these new adjustments in bios to see if we can make changes to were the fans RPM change?

 

Does anyone know what the MD5 checksum is? Has anyone tried the g74sx bios? I sure am tempted to give it a whirl.

Question, How do you test the bios? If it flashes its good. If it bricks its bad.
Thanks You guys with the moded bios sure are lucky.

 

MD5 Checksum is a confirmation that the file is intact the way it is supposed to be and not corrupted.

When you download the BIOS ROM, use an MD5 program to generate the MD5 sum of the ROM file and compare it with the MD5 sum in the first post, a simple prog for this it: Home of the MD5summer

And yeah, if it works it works, if not, bricked lol. But it's the same chances u take when you flash a normal BIOS.

 

Also if you do flash be sure to use a HDD or flash drive format with FAT32.
Do not use a NTFS format HDD or flash drive. to store the file to be flashed from.
I found the safest way to flash is by using the easy flash utility in bios
its quick and simple.

 

Ok. Thanks for the help. I flashed it FAT32 in the bios, and is working for the G74sx. Good job! I tried this myself once before with AMIBPC V 4.53, and it bricked my laptop. I didnt have any idea what I was doing. What a mess that was. I did happen to notice that there were no ram options. When I was editing the .203 file I think that I saw the options for ram in there. When you get some time, can you look?
Anyway I can confirm that the G74sx ROM will not brick the laptop. I even changed a few option like fast boot and BDPROHOT. Works good.
Thanks for all your work

 

But making some changes in the now visible options will Brick the laptop.
If you see a option with something about CPU Flex that is disabled do not try enabling it,
after save and exit the bios the laptop will no longer boot.
All I get now when trying to power on is all lights up top come on then flash go off then repeat this over and over.
I've already disassembled and removed the cmos battery with no help to recover.

Edit: anyone here have the means to re-flash/reprogram a bios chip?
Anyone know the correct keys for G53SW to hold at power on to try and educe a blind flash?
If someone would please do a test run and report back what keys got it to bring up the flash utility at power on?
Maybe there is hope if I can some how get it to do a blind flash, I already have a CD with the stock bios file on it made up.
AMIBOOT.ROM

 

I would hate to brick the bios . This is so tempting since I would LOVE to mess with the bios and stop the throttling and just poke and prod, but after seeing a bios mishap, I am so scared now.


I saw your video, one thing I would like to see is having the number lock on boot option there, I prefer to have it on all the time.

 

Not sure why fail safe didn't kick in. ASUS BIOS comes with 2 settings, fail safe and optimal. And seems like it's not even reading any drive, it's a dead end unless you reprogram the BIOS chip using Soic programmer or RMA it. To do crisis recovering first of all, it needs to be able to read any drive. And what yours is doing seems to be just power on and off.

 

Actually the bios is safe to flash, options like disabling Bd-prochot, speed stepping or fast boot doesn't cause any problems.
I even had played with some of the fan speed/temperature control settings without any problems, they didn't seem to make any difference, but no harm.

Without being able to get into the bios I can't give the exact name of the setting I changed that caused my problem, all I can give is it said something like CPU Flex witch was disabled & I enabled it saved & exit is when I had problems.

I had made many changes to different things & saved changes before this without having any problems.

Still hoping someone will help me out and do the test at power on to find the correct keys to get the bios flash utility started at boot.

Thanks in advance to who ever will help.

 

man , you should have not messed with all stuff inside it , now you have a paper weight , try to rma or buy a programmer and reprogram the bios chip which is going to be very hard.

 

Yes it does seem like its just powering on & off, but there is some activity from the DVD drive.
The light on the DVD drive does flash while it doing the power on and the lights are still on.

I hate to think about another RMA but may have to or just sell this 600+$ laptop as a part out.
I can always use the new 240gb SSD I just got in something else.

Is the bios chip close to the cmos battery? I also see a plug close to those too.
Wondering if that plug/connector is for connecting a programer to?

 

Ya maybe so much shouldn't have been unhidden to start with. You know someone is going to try them.
Why you say its going to be hard to reprogram? Have you done it or have any knowledge of doing this?

Its differently not like a motherboard bios for sure. Never had this many bad bios out of hundreds of M/B I've owned and flashed.
Seems these laptop bios are very picky and can drop dead at any given moment.

 

That sucks, again, I just un-hid the settings, frig knows if they all work or not. That's why I have the warnings.

http://forum.notebookreview.com/asus-gaming-notebook-forum/668404-g73jh-bios-chip-replacement.html

You'll have to follow that to flash the BIOS. If your laptop is just powering on then off, that's a dead BIOS at that point and there is not a "blind" way to flash it as the machine does not boot at all. It needs to boto in order to read from the CD. How long did you remove the battery for? Should be removed for close to 10 minutes to make sure.

Seems odd that would have caused a brick. Sucks.

 

I had the battery out close to a hour one time. Ya just my bad luck I guess.
This is the 3rd time I had a bios blackout on this same laptop.
First time I don't have a clue what happen, was in bios making some changes and dead bios.
Second time my fault for not knowing not to store the file on a NTFS format when flashing. Had some small glitches I thought a fresh flash might fix.
Now this, if it wasn't for bad luck I'd have none at all.
At any rate I don't blame you. I knew what I was getting into, kind of. lol
When the flash went so well and making some changes that didn't cause any problem I thought it be safe to make others one at a time.
Heck they are there you would think they could be used without any harm.
At worse you would just need to do a bios reset to recover.
Unlike a motherboard there is no bios clear jumper, but there should still be a way to do so you would think.

But this time is kind of like the 1st time when I had problems. Just making a simple change in bios trashed the bios for no reason.
Really makes me wonder if its really just something very sensitive about these laptops & there bios failures & not the fault of make a simple bios option change.

 

hehehe , your asking me about bios , lol @ lol .
I really was playing with bios , but at some point , I thought most of the hidden values on bios makes no improvement , so I left it as is .
I know a way to reprogram the bios chip without desoldering or with programmer , im still into that project , I would make the tutorial soon time , until that im sorry , if you laptop boots and stuck at blank screen I would have helped you with a blind bios flash tool, that I made, your problem seems odd so only way should be reprogramming chip or my tutorial .
to do the reprogramming you will need an full asus g53 bios ( which will take decades to find , until someone dumps using an programmer ) OR YOU COULD
take your own bios , but its very difficult to bind the firmware part and bios , so easiest way is buying an bios chip through ebay and soldering it to mobo.

 

Help me with blind bios flash tool, give me the know how to try?
If it doesn't work nothing is lost.
if it comes to it I can get a bios chip here if need be.

Edit: I now have it where its staying on and its trying to read the CD that's in the drive.
I just don't know the correct keys to hold to try a force blind flash for this model.

 

what do you have on your CD ?
download the latest g53 bios and rename it to AMIBOOT.ROM and write it to CD ,and insert the cd and turn your laptop off.
now hold ctrl + home and press the powerbutton , keep holding the ctrl + home till you hear the cd spinning ,
and keep it for 5 mins like that , and hold power button for sometime to turn off your laptop , and now , power it again , and see if the problem has gone.

 

I have the G53 bios on the CD renamed to AMIBOOT.ROM.
There is only one bios file for the G53SW 203.
you say hold ctrl+home till I hear the cd turning, but do I hold those for the full 5 mins. then release then hold power till it turns off?

I think I had false hope as I had all memory chips removed and is why it was getting more activity from the CD rom plus staying on.
Putting in a single memory chip it goes back to on off on. Oh well to bad.
They should start making the bios chip removable like desktop motherboards are, it would save everyone this pain.
People like me would just buy a bios chip & fix it themselves instead of RMA to get it fixed.
I have hot flashed a many bios chip in my day, if the laptop was the same then I could restore the bad chip for a backup.
Thanks for trying to help.

 

I flashed the bios, and all is well. I will try and find the setting so I can help out with keeping things safe.

 

G75 Guinea Pig lined up right here

 

What exact G75 model?

 

G75vw-bbk5

Best Buy. Probably the most common one.

 

Here is the option I enabled " CPU Flex Ratio Override" what ever you do in bios stay away from this option.
Had I seen this Post before doing so I'd still be alive.
Options in the menu where it resides should be hidden in any new mod releases.
Be nice if someone with the ability to reprogram there bios chip would take time
to note/test what is safe and what is not so a new release can be made with all unsafe options hidden.

Ya I know it would probably take a lot of time and testing, if I had the means I would be more than glad to.
I have nothing but time so that isn't a problem. lol To much time on my hands is probably what gets me in trouble as it is.

 

Wonder if it would be possible to piggy back a bios chip on top of the old one to get it to boot & then flash the corrupt chip?
Has anyone ever tried this or know if it would work and not kill the new chip by doing so?

I do have a Asus U50F that I might could do a hot flash in. I have been able to in the past
by using a different motherboard then the one with a bad bios chip to flash the corrupt chip.
This would be a real challenge with a laptop I'm sure but could it be possible?
Having bios chip socket on desktop mothebroard makes it easy doing a hot flash.
I've done hot flashes with Abit IP35 Pro in a Abit IX38 & with a Asus R3E chip in a Asus X58D
Actually the R3E is quite simple with its dual bios chips, if only one is corrupt. Just a flip of a switch.
Maybe one day they will have dual bios chips in laptops.

 

I don't see why dual BIOS chips are not standard NOR don't I see why every single one of them isn't socketed. It's stupid really. It's like saying "Oh you bought this car but if the engine or transmission goes.. well... tyou need to buy a new car. It's 2012 and you would think that there would be redundancy built into newer hardware or just a simple better way of doing things. Even if it costs a few cents more, it's worth the time.

I remember back in the day I had an old Pentium 233mhz machine, 32MB ram, 4GB HDD lol.. 4MB video card... even then the BIOS was socketed. Like come on! lol

 

So wait you unlocked a feature that could kill... Nevermind that, thank you for the first unlock! I see you did not do that. Forget what I said

How do you go about unlocking features? I am curious as I would like to learn. I obviously will not turn on/ unlock anything unless I have a method of finding what it is .

 

I would think that changing any setting in a bios would not corrupt the firmware. I think that this is what has happened. If you cant fix it with a clear cmos, then it has to be the firmware. That is a hard file to find. Asus will not give it to you nor sell it.

The hot flash will not work. You need a new uncorrupted firmware to reflash along with the 2.5 MB .203 bios file.

This sucks,I know. I have been there. I had to send my G74SX To California Computer. They are one of the contractors for Asus For the USA. They can try to reflash for I think 75.00. But Will try to sell you a new mobo for 475.00 + 75.00 install. They do not replace EPROMS. In the USA repairs are simply remove and replace.

The only other way is to have someone with an eprom reader read and save the file. Then reflash, if the chip is ok that is.

The bottom line is CPU FLEX RATIO OVERIDE enable = new motherboard.
I am not very happy with Asus Laptop side. It is not like the motherboard part. The bad part is ther isnt enough information on the Asus laptops, how the work. Everything is trial and error, or risk. That sucks

 

This is the screen wolf is speaking of.

 

Yea that's it, I thought it was CPU Flex, but after see the other post about it I thought maybe I was wrong and just copied pasted what they called it.
Most of what is seem in the screen shot below is in most of today's bios, except the CPU Flex. I've never see it before now, think that is what draw me to it.
Changing almost any of the others would probably not cause any problems.
Most of my overclocking motherboards have all the other options shown there are unhidden as standard.

 

The EC Firmware is contained within the BIOS file so a reflash will fix this/chip replacement.

 

Asus G75VW: Based on BIOS 207

Version 1: G73VWAS.207Moddedv1 - https://docs.google.com/open?id=0Bzj6JjnAJZjjc282QkxUNlRDNFU

Everything unlocked!

MD5: 74335911f2aaf1eb9507f91930a662ee *G75VWAS.207

NOTE: I HAVE NO WAY TO TEST THIS, USE AT YOUR OWN RISK!

 

So Are you saying that only file on the EPROM is the 2.5 MB .203 file?

 

From what others have said and what I have read and researched, yeah I'm pretty sure.

 

So I attempted to flash this and It will not let me from outside windows or inside windows. It claims it to be an invalid bios.

thanks
