trying to post in this too … what it mean when a gop only vbt only have intelgraphicsmem magic header and no bios_data_block? thx
Looks like a normal Haswell to me, But you weren’t very specific about your intentions or where things didn’t work out. In addition you didn’t ask any questions but just made a statement.
So your conclusion is correct, might as well be user related or a more difficult bios…
Hello!
I am sure this is not the right place to ask but at the same time I cannot find the correct thread where to ask for help so writing in here.
I have a AMI BIOS that has no Onboard EFI drivers or VBIOS or VBT installed.
However, this laptop that has this BIOS installed has an integrated Intel GPU.
The BIOS also has all the options necessary for Intel IGPU to work, even shows the GOP driver version (even though at the moment it shows N/A as it is not installed in BIOS).
My question then: Is it possible to manually insert VBIOS, VBT and GOP driver in my BIOS as an attempt to try and ressurect my Intel IGPU? At the moment everything is hardwired only to RTX 2080 but I would like to revive my Intel IGPU if possible.
I already tried UBU Tool, but it only lets the user to replace the existing ones and not insert brand new files in BIOS.
Hopefully someone can help me out.
Thanks!!!
not must works .,.,some is locked by EC fw
and setup is very dangerous “PEG port + SA domain” for switch igpu or customized EC fw
what have ? no OPTIMUS ,.,. MUX switch ? ,.,.only direct D-gpu on this notebook ?
edit,
may be disabled for CPU functionality “some models had it banned i-gpu”
It can be a mobo design ,.,.too much power draw around cpu or heat ,.,.etc
I will add that editing the video output on a laptop is extremely risky !!
possible to get a black screen forever! cmos reset does not help
Only direct gpu.
I have a bios flasher. Still dangerous?
Laptop model is P775TM1-G.
I was just wondering what would happen if I could insert the necessary modules in BIOS and tried to boot using Switchable Graphics or something in BIOS.
Or atleast get it recognized in Device Manager.
do not risk for unnecessary igpu ,.,.your notebook is premium “better than lot another” for direct d-gpu
if you need better ECO setup - AFTERBURNER / cpu low profile
not must helps HW flasher “EC fw or pcie detection sometimes stuck” and is very hard switch notebook back to life !
I also only use d-gpu 
,. igpu has no advantages “no performance / screen quality is bad ,.,.CPU is limited etc.”
I guess you are right.
But there is one advantage for Intel IGPU:
4K UHD Blu-ray playback only possible using Intel GPUs.
Otherwise I guess no point of it.
Thanks!
I’m not sure about this issue 
but why not works on NVIDIA ?? “HDCP status” or you using custom drivers ??
edit
rtx2080 i think is compatible ,.,.uefi mode / clean drivers ,…,but sometimes must contact manufacture for vbios “by default is HDCP disabled” -MSI for example
try luck 
has anyone able to edit “bdb block”? thx
I purchased Chinese gm45 motherboard it’s have lvds display output, my requirement is 800x600 18bit but it have 800x600 24bit so the image size is good but there was garbage display due to bit issue
I want to change display color bit
I uploaded my bios understand attachment

Hi all,
am i dreaming of …, or is possible somehow implement vga bios in new bios for +12th gen processors with “Intel UHD Graphics 730” ?
Another q: same thing but is about network driver “Intel(R) Ethernet Connection (17) I219-V” that is available just as UWP driver, im
dreaming to downgrade bios driver to some older network driver that was working in win7, xp, …etc
thx in advance and sorry for stupid noob questions
Theres no more recent sources of more recent tools or config files for modern chipsets/vbios, past the SKL/KBL/CFL/AML platforms skus.
Irrelevant for users using a PURE UEFI system, vbios is legacy only.
Hi MeatWar,
thx for prompt answer, i got some time to check it out, seems that “pure” driver will probably work just in win10 older versions 2015-2017.
But installing that driver on win8 doesn’t work. probably is that pure driver not “normal exe” as drivers for win7 are (ndis62).
I was hoping use “Intel(R) Ethernet Connection (17) I219-V” on winxp-win8,
for now i use just some slow wifi stick as alternative ;-(
about vbios, yes is legacy only and many things aren’t possible under uefi, so i need start old pc to do things like winxp, grub4dos, … and even network booting on uefi isn’t easy, … all config/booting files don’t work on uefi, even modify all for uefi is a nightmare, but thx again for your help.
how to debug why [drm:intel_bios_init [i915]] VBT signature "$VBT SNB/IVB-MOBILE ", BDB version 165 shows up or not thx
Do you have access to the BMP tool for CherryView? I developed a custom (non UEFI) BIOS and needs to adopt VBIOS to some boards with different display port configurations. I’m familiar with BMP and have used it for CedarView and BayTrail, but the BMP for CherryView is no longer available at Intel site.
im need some explanation: VBT is using only in legacy csm mode, UEFI using intel gop .efi, right?
or VBT can affect on some in uefi module?
i have specific issue with z790 and gtx 3070 ti (update vgop not help), slow boot, black screen, juddering.
The VBT is present in Vbios and in GOP driver, the system will use vbios if set a Legacy and EFI GOP is set as UEFI.
Both have nothing to do with OS boot as long as they were already initialized and have output a video signal.
During OS boot, a defective gpu will have impact on OS boot, when this one loads drivers and initialize 2D/3D routines.
And this maybe your issue here…
EDIT: Your issue was reported with a RTX 3070… so that’s the possible card with an issue, not cards that you didn’t mention earlier.
“…i have specific issue with z790 and gtx 3070 ti”
i think that not OS issue because i put gtx 1060 card from pc (that pc is 8700k + 1066, startup time igpu - 4s, with pci gpu - 6.5s) on my z790 msi board and startuptime increased from 10-11 to 14s. That is POST time.
z370 - 6s
z790 - 14s
and im see in my led board gpu initialization is 6-8s vs 1-2s on z370 board.
Just curious, I can’t find my hardware flasher so I am not going to attempt it anytime soon.
I have a NUC 12 Enthusiast with an A770M (Serpent Canyon), seems abandoned for dGPU firmware updates, it seems Intel never released a firmware update with its drivers, there was one beta driver that included a matching firmware.
ARC firmware consists of 4 individual firmwares\parts.
In ARC Firmware Tool, “firmware” and “oprom (code)” are universal as long as it matches SOC/GPU.
Both “oprom (data)” and “fw data/config” are customised per SKU\vendor.
Do you think cloneVBT might work for some ARC oprom-data files?
I have attached a zip of the source files and cloneVBT output.
My aim is to have all ARC related firmware on my system as up to date as possible, I have had experience of newer ARC firmware improving or fixing graphical issues like corruption and flickering on multiple systems.
I believe ARC firmware is more important than the usual vbios/gop, Intel does roll out firmware updates with their drivers after all, unfortunately some models/vendors get left behind.
More info if required:
firmware can be downloaded with the above tool. the below firmware compilation matrix link, or you can download direct from Index of /downloads/Intel-FW/
