L702x Modded GPU BIOS

I've tried back porting boot manager once and it has changed the way F12 menu worked, so I believe its the one and there only.

If its just included, the answer is no. If its included and initialized with bcfg driver add 0 the answer is yes. Later phoenix tool version of 2.13 seems to include terrific changes for module integratioin into the firmware.

bcfg is not recognized as an internal or external command

 

Shell 2.0

Sent from my Nexus 7 using Tapatalk HD

 

EFI Shell version 2.00 [4660.22136]
Current running mode 1.1.2

 

Well, it obviously doesn't support this command, search for a 2.0 binary that is able to handle it.

 

Ok , i will find it
but still there is a question - bcfg is a boot configuration utilyty that adds boot configuretions to nvram, so ... it would not be possible to run shell from recovery capsule because it doesn't use nvram as configuration storrage

one more question do you know any way to invoke arbitrary protocol from a DXE. e.g. start setup utility - load command runs only PE entry point, which is for most DXE's just registers protocols that should be actually invoked to start utility

 

sorry, we are unable to test if bcfg works from crisis boot or not as UEFI is disabled on our platforms. but I know for sure it is able to utilize nvram as boot order gets preserved when loading crisis capsule and as suche one can asume nvram is intact and parsed properly, since the order is actually stored there if you look from dmpstroe.

i'm not sure on the protocols, sorry. not my cup of tea. worth asking dmazar about this as he is knowledgable is this area.

 

As far as I understood dmazar is the developer from Project OS X Forums , co-author of clover ?

Thank you, for your help ! really appreciate.

 

havent read past this point yet ..... wanted to know how you are gtetting on with this, is it stable at 1600 with 32GB ?

I always considered tweaking in the BIOS a bit of an art, because usually not just one thing was needed to be alterred for increases in such things....

there are from what i have seen so far, many new options, most of which i dont understand at all....

what i do seem to have picked up is that, if we flash and adjust things, we better remember what we changed, because next flash and they all gone LOL

 

turn off all power saving crap related to usb 3.0.

This has been an old problem, also make sure your using drivers and firmware from station drivers. I have this info saved in a text file for when i need to update and have forgotten

as you can see i keep the current installed safed in there as well

EDIT:
Install Firmware first, then Drivers

 

I've read somewhere that the system doesn't like booting from that port, certainly not with a DVD drive connected via eSATA - it could be a boot priority thing of course, but i'd test in the main DVD drive and also the USB on the other side (not the USB 3.0 that is on a daughter board)

EDIT:
just read the rest of your posts after/before that one - ignore my comments, i see you bricked it as they were all disabled hehehehe - good to see you got it sorted

 

looks like we are running similar configs, Mushkin Chronos Deluxe 120 here, with the Seagate XT 750 as second drive, and also 32 GB of RAM,

that XT drive works real well doesn't it as a second drive
No Ram Drives for me at the moment, and i also Haven't changed the paste, i'm not a gamer, and if it overheats i'll get it fixed under warranty still got 2 years warranty on it as well

Interested in this modded BIOS mainly to unlock the RAM speed, to be fair it is running pretty fast as it is, and i'm dreadful for updating stuff LOL, my GPU drivers are old, the RST drivers too, and i need to update the firmware on the SSD lol

Will have to read through this thread properly, and try and check what i might need to alter when i flash the Modded BIOS

 

Can the 'Primary Display Selection' be set to manual, then select the nvidia as the primary? Love to get round the optimus nonsence.

 

Anyone?

 

The update mod BIOS from you,
Successful to modify higher memory frequency 1600MHz.
Thank you very much.
but, I do not know how to enable integrated graphics（Intel HD Graphics 3000）.
Because I need the Intel WiDi.
Please help me.
My rarely come to this forum, but can be sent to my office email: [email protected].
be indebted forever.
My NoteBook:
L702X-3D

as far I know, you guys cant disable optimus via the modded bioses.




this options looks for selecting the first video outputing device while the machine is booting.

as far I know, there are two versions of the L702X one of them is the 3D version wich dont have optimus at all (it just use the NVIDIA CARD), and the other version of the L702X uses optimus..

there are probably differences at the hardware level of the machines, so probably this cant be done.

 

I was hoping you could select the nvidia as the first device (would be a big help). In the 'Primary Display Selection' I would have expected Auto, Nvidia and Intel as options in the menu. Can you select anything but Auto?

@trouble_man

auto, will probably detect the avalible video devices and will output the video to the one conected to a screen or the one most recomended.
that option I supose it is likethe one in the desktop boards, the one it let to select pci , agp or pcie as primary device to visualize the setup on the screen.

@caizz520

the link works for me.

do you mean you get a corrupt or incomplete download?

 

Oh! Really bad.
This really makes me so disappointed.

I live in China, because of China's Great Firewall.
Can upload it to SkyDrive?Thank you.

 

I just need a confirmation of A19 Mod Bios without Gpu Mod!Is it working without any issue?I just bought Corsair 16GB 1600Mhz memory!!!

 

capitankasar would you be able to add cpu overclock options to the dell xps l702x a19 bios

 

@caizz520

my net isnt working properly those days, so its very hard for me to upload big files, also dont have account there, so if someone ele can upload it to someother place, it would be good ^^

also consider using a proxy if your ISP keep blocking sites.


@Redtulips7

it has been tested before, seems good for many people ^^

@ausplayer92

I tried the same with L502X, cant OC it via BIOS

the only way I was able to OC my L502X was via hardware mods in order to mod the intel ME firmware settings.

it unlocked BCLK overclocking so I managed to OC my system included my I3

the procedure to unlock BCLK overclocking at the L502X and L702X isnt easy, and it is risky also I just was able to get like a 5% Overclock without crashes.

 

Thx capitanKasar,can you send me a link to latest A19 Moded bios without Gpu Mod?thx

Just flash it!!change Memory from 1333 to 1600Mhz and WEI increase from 7.6 to 7.8!!!wow...only thing I see that Cpu fan running constantly since the flash even it is set 85% max in the power option!!!Fan is not running high but low speed

 

Anything I can do with Fan constantly running low to high speed?

 

I've dumped bios chip by programmer - so, now it is possible to unbrick by "the hard way"
bios dump
With unlocked descriptor - so , it will be possible to backup/flash full image from windows

Dont forget to restore original serial and mac address after flashing this image !

@capitankasar
can you share the link where I can read about overclock from ME ?

 

@followme


very nice job

how did you dumped the chip?

if you did hardware mods, can you share the pictures of the hardware mods?

do your BIOS chip is also the 25Q32BV /25Q32BVSIG?


did you built a cheap LPT programmer like I did?

as far I know I was the only one until now who built a hardware programer system for his xps machine.


and yeah, with the bios dump, people will get your same bios password, tag number, mac addresses ... so it is a little dangerous to share that, people will "clone" your laptop.


to hack the ME region, you will need to hack your descriptor first

here you have more info

http://forum.notebookreview.com/del...ed-bioses-download-gpu-voltages-more-129.html

basically do this

open your firmware backup with a hex editor, look for

00 00 0B 0A 00 00 0D 0C 18 01 08

then change it to

00 00 FF FF 00 00 FF FF 18 01 08

then flash it/program it.
that wil unlock some apps to read and flash stuff while the machine is opened


as for ME cracking , give a read to this topic

Lets enable overclocking on all 6 and 7 series laptops

also read stuff from the page

118 to the end of the topic

(UEFI) Dell XPS 15z L511z modded BIOS - and HOWTO - Page 118

I managed to hack the BCLK by myself using this method.

however , while readin,g keep in mind some values are only from the L502X


also while using fitc, you will need to get just the ME image.

open your whole chip image with fitc, and a subfolder will be created, inside you will find another one named Decomp, and then a file named ME Region.bin, you will need to focus at that file.

that wasnt an easy subject for me, spent many time and effort until I finally managed to overclock it, and I had to restore the chip image many times since I actidentally bricked it several times until I finally got the good one.

let me know how If you need more help

 

I've dumped the chip using this cheap programmer from ebay
Tried to dump using raspberry pi + flashrom, but chip is configured for multichannel spi and wasn't detected by flashrom

Chip is a Winbond 25Q32BVSIG, like the one in 502x

I didn't made a removable mod - just soldered out -> dump -> reflash -> solder back to mobo

I don't see any issues here for me - I don't have password set, my warranty is void after all this actions , so service tag doesn't means much now and mac address clone may be an issue only for L2 network lvel (e.g. both laptops in the same room) . Sooo ... Nothing to worry about much

Already did this - the image I shared comes with unlocked descriptor (thank to @CodeRush for manual how to do that )


Thank you captain for sharing this links and how-to's !!!

 

oh, I see

then you soldered/desoldered like I did with my first bios chip at the l502x

that may work for one or two flashes, but if you flash too much, chances that chip malfunctions by one of the legs break or the soldering iron heat damage the chip are high.

that happened to my BIOS chip, that was the reason I ordered more bios chips and the sockets ^^

I needed to reflash several times.

as for the bios chip image sharing, well, bad people can use it to make bad stuff, and since they have your data, the coops can come to you in the worst scenario.



well, if you already have descriptor unlocked, then you can go for ME modding.

do what I said, open your whole chip image with fitc, and get only the ME region.

then, do following ; )

1 - open FITC
2 - load ME Region.bin (820 kb foe me) on FITC
3 - make changes on ME settings, (I suggest to read the 1.5MB FW Bring Up Guide 7.1.20.1119.pdf file included at the files I uploaded at the tech inferno topic)
you can also take a look to my modded ME firmware to see what changes I did ^^
after mod the file, select compact image option at build options and generate imagen , and error message will appear, click OK
4 - now copy the outimage.rom (896 kb) to somewhere
5 - open outimage.rom with hxD hex editor

following steps may be different for you, I used it because the modded FITC image size was different than my original ME Region.bin and I needed to fix it.

6 - select block (ctrl + e) 0 - FFFF
7 - delete selection
8 - select block (ctrl + e) CD000 - D0000 (end of the file)
9 - delete selection


basically this is needed when you compare both modded and unmodded me images they should be the same size and the begining of the file should be the same.

after that, flash the modded firmware with the modded ME image with fptw64.exe and reboot.

then install intel XTU version 3.1 (XTU-Setup 3.1.201.5.msi was the only version wich worked for me)

if you can now tweak the BCLK over 100 mhz and confirm it works with another program such as CPU-Z you will have suceeded with this mod

if your laptop doesnt boot while rebooting after flasihng the modded ME region, it is hard bricked, and you will need to hardware reflash your chip using the backup file.

I needed to make it several times while modding the ME firmware, hopefully, you may get it with all the info I provided and comparing my modded ME firmware FITC settings with yours

let me know if you get it working!

I also was just able of enable just BCLK overclocking, so it you unlock any other setting, let me to know too

edit:

oh, I forgot to mention, that, after you OC by BCLK, you will have sync issues with audio and games.

to fix that, you will need to:
run

and also run wintimertester 1.1 some time until all the timers get stable at 1.0000 ratio

I already have 10 more Winbond chips - but can't find where to buy socket like you used for your mod

Not in my country
And as I said beefore - any sensetive data (like mac address) exposed only if laptop connected directly (without routers, ISP gateways, proxy servers , and other level 3+ hardware/software) to victim's computer
Anyway - it is possible to fake/change any such data.

Thank you ! will try to mod ME
Will report later

DL link is missing ...

 

yeah, thats true, is posible to fake those data, I even though of testing by editing the BIOS image with a different MAC or tag to see if that worked.

I'm almost sure it would work, however I have no uses for that, and the mac can be changed from windows with several software ^^



as for the sockets install, I had to cut a small plastic square at the case over the chip place to make the socket fit perfectly, but it is almost unoticiable.

the socket isnt also too big, so with a little modding you will be able to put it

and at the worst escenario, you can maybe reallocate the socket from the chip original position by extending it using wires to another location like the expansion door of the laptop, that will be way easier to reprogram it several times, it will save you to take appart the whole laptop everytime you want to reprogram it.

also adding a socket to the programmer will be good

using sockets at both motherboard and programmer sides will save you from soldering after every reprogram and it will be a lot quicker safer



oh, my bad about the DL

here is it ^^

WinTimerTester_1.1.zip

it is at the another link anyway, I get confused sometimes while composing big posts

oh, and if you love hardware mods, you may like the extra USB ports you can get from minipcie slots.

I added internal bluetooth using that trick on my L502X

 

@ capitankasar
Wanted to personally thank you for your Mod Bios for my XPS17, I can now open my RAM to 1600Mhz and enjoy all my games with smooth FPS, initially i was apprehensive doing this cos i`m not exactly comfortable messing with anything like this, i`m a Tech Newb!! but it really has been a smooth learning curve for me, nothing went wrong, GPU VDDC is at 0.8270 at idle and 0.9200 when i load the GPU @ Stock values, fan is sweet kicking in at 71-84 C, this mod works so good, thanks a lot, will now try clock speeds for my GPU and see what my 555 can handle.

 

hello, my English is bad: P
Install the mod BIOS for the graphics to 770 core and 1000 on the memory

Well I shot this pantallado blue.

Does anyone knows what this error is due?

 

It ment your overclock is not stable or Driver issue!!!lower your memory clock to default 900 and Core to 700Mhz then run the stability test!if it pass raise 5Mhz at a time and rerun the test until you reach the maximum overclock...

 

Hi I did what you told me
core 770 memory 960

What program you use to check the stable?

I get to play for several hours

The fact is that without the mod came to run BIOS core 740 memory 1000

 

Hi everyone im new to this website however owning an XPS L702x i stumbled upon your vbios mod firstly id love to say a HUGE thanks to the person(s) that rewrote the bios file im now using A19 modded and using EVGAPrecision ive manage to get a nice stable 830mhz core with 960mhz memory its roughly added 7-9fps within my games and im albe to play Call Of Duty almost completely flat out @ 1920x1080.

i wondered if you were able to mod the bios further?? for reasons of msata ssd in wwan slot?
also can the motherboard actually support 1866mhz memory? im running 1600 @ 1333 atm but only because my cpu wont allow it to run at 1600, im going to upgrade the cpu to a 2960xm, i cant really see too much of a problem with heat as my temps dont ever go higher than 80C they can run happily up to 95C. i have moded the vents removed the mesh so it can breath. if any ones interested this did stop the fan noise issue people struggle with.

anyways hope you can help

carry on the good work

James

 

Furmarks for about 10 minutes to test the initial stability
Then Kombustor for half an hour
Then loop heaven 4.0 an hour
Then gaming, like Crysis run at least for an hour. Just fine tune it from there till it won't crash,,,,,,,,,,,,,,,,

 

Wwan slot is a PCI-e slot - not mSATA, despite electrical compatibility, it won't work because data lines are connected to PCI-e controller and not to SATA, and those signals are not routed to proper destination - sooo , it is not possible by hardware design , and not a software issue

memory frequency are limited by memory controller which is built into CPU, and according to specs max supported by 2960xm frequency is 1600 MHz. IMHO - not worth to spent money for such upgrade

 

hi thanks for the reply, the msata has its own sata controller tho does it not, i could see why it might not work as a boot device but i want to put my games on it to keep them fast

i see your point about 2960xm ive been considdering the 2920xm instead its about £100 cheaper and still a powerfull chip

 

I was also considering getting 2960XM(TDP55W) but got 2860QM(TDP45W) due to XM will generate more heat where heat sink limited to only one single copper pipe,and make no sense getting it if you can't overclock it!!!!!

 

It is not that controller that you think it is
It should be like this:

flash <=> disk's SATA controller <=> Host's SATA controller <=> System Bus

using mPCI-e port you will get next:
flash <=> disk's SATA controller <=> Host's PCE-e controller <=> System Bus

the MSATA has its own controller - but it expects to be connected to a different one (SATA not PCIe ) from Host's side

 

My max supported memory speed is 1333 with my CPU (I7 2630QM), it now running at 1600, just fitted the Corsair Vengeance 2 x 4GB 1600 CL9, set 1600MHz memory speed in BIOS and booted.
No stability tests done, see how it goes over the next few weeks.

Hi guys
This message is for everybody, but in particular for capitankasar! I need Help! I've installed successfully your modded Bios A19 on my XPS L702x.
The bios features are great, but unfortunately my laptop doesn't start! When I push the power button, the system start booting Win 7 , than, when windows logo is on the screen, the machine crashes with a fast blue screen than restart! It seems a RAM problem (I suppose...), but if I set the value to 1333 or 1067 on BIOS parameters, the result is the same.
I tried to start with your Recovery CD, but when I see win XP Logo, the laptop shows another bluescreen and freezes another time.
I tried to boot with an USB Pendrive created with the "Crisis BIOS Recovery" tool with the original A19 BIOS, but the XPS starts with CPU Fan at max speed and Power Switch flashing, but nothing happen.
There is a problem with PHLASH16.exe or MINIDOS.SYS on the USB Pendrive?
Please, Help Me!
Thanks a lot and sorry for my bad english!

 

@febo_1974

well, the BIOS recovery method for the L702X seems different for the L502X, because it doesnt seems to load the BIOS capsule properly.

for that reason, it need the recovery cdrom inside, but it also need a usb stick with the BIOS.cap file at the root.

as for the issues with your laptop, try load default settings in bios, save, and restart the machine, try booting the machine with default settings, you may changed something while browsing the advanced menus.

if the results are the same, you can try reflashing. (also, if you want the recovery cd to work without boot the laptop in recovery mode, you will need to change the hdd mode at the advanced tabs from the bios (you dont need to enter in any sub menu, i think you had to change AHCI to IDE, but not fully sure), also make sure you leave the AHCI setting back after flash the bios from the recovery cdrom).


note the recovery cdrom flash a unmodded bios, so you will have to flash later the modded bios back if you want to get the advanced settings back

 

@febo_1974

I suppose that captainkasar's bios might have a different sata setting than your previous bios, therefore windows installation crashes. Captain, please point febo to the setting in your bios where you change sata mode either to IDE or AHCI. Then, febo, just change it to the other one. This looks like the cause to me.
