Workaround on a Vaio VPCCB

Hi guys, I’m new in the forum and have a request regarding my bios.
My laptop is a VPCCB3S1E with Intel HD 3000 and Radeon HD 6600m Series, HD 6630m depending of the driver I use. I installed W11 and tried many drivers, officials, Unifl and modded ones. Every time I reboot one of the drivers starts failing and windows installs automatically their own drivers. What I think could make a big difference is to flash a mod bios that allows me to disable the Intel HD 3000 and use exclusively the discrete. This is the dump of my bios:

I found another version R2110V2, but its size is about 2MB
Any help will be appreciated

Not enterely sure… this is old hw gen, but as soon you disable or change some graphics settings in “unlocked” advanded mneu settings, next boot will have no output.
My pov only.
Wait for other users

EDIT: You did notice the warning about WDDM2.0 driver model on W11 on W10forum

Thanks for your quick reply,

EDIT: My request is orientated to find any updated unlocked Bios for my laptop, the ones I found online seem not to be compatible with mine. The gpu issue isn’t a huge trouble since I found a super cheap minipcie-eGPU adapter. If by chance, anyone in this forum could provide any idea to fix it, will be obviously better.

if at a bios level no changes are possible, then do you think a registry level could be useful? this HW is from about 2012, chipset HM65.
I tried installing official drivers for Radeon HD 6630m and HD 6600m series from Sony, HP, DELL, different modded drivers I found online, the ones that worked couldn’t keep working until the next reboot. I kept a working installation only suspending the system until windows changed to the faulty Intel graphics on its own. Maybe it’s something that can be fixed adjusting the parameters of the way how windows manages the graphics.
I searched for further informations, many users had the issue of the screen going black after boot while using both drivers, the modded drivers gave a solution but it doesn’t seem to work on W11.
This situation seems to be resolved by someone who knows a bit more than me about this graphics and windows management.

Have a nice time, lets hope someone replies :slight_smile:

Hi friends, I post again with an Update:

I bought for very cheap a VAIO VPCCB3S1E.

I’ll make the long story short, I could get some help from the wonderful community of bios-mod. Thanks to them I learnt how to dump my bios, and use the tools to modify an AMI bios -My version is R2100V2, 4MB-, I asked them if they had some updated version and I found a ver. R2110V2, 2MB which doesn’t fit in size, I tried to flash it but I couldn’t anyways.
The problem with this model is that it has an iGPU intel HD 3000 and a discrete Radeon HD 6630m. I searched for modded drivers, but couldn’t make it work properly on Windows 11 24H2. The iGPU is making lots of trouble, since there’s no compatible driver. The Radeon could work almost fine with a 6750m driver, until Windows re-enables automatically the iGPU.
I asked if I could get a modded bios to disable the Intel GPU, on this model I don’t think the graphics are working in the so-called hybrid mode -Stamina-Speed- on other Vaio models. The dedicated graphics seem to work normally alone.
If I deliver a dump, could any of you offer me an newer, unlocked bios with all the menues to see if I can get the Radeon to work alone and the uefi boot options?
I tested newer hardware on it, a NVME was working @pcie 2.0 speed, but it won’t boot at least I use bootcamp or any other app for that. I know a lot more about hardware, than software. If you had any questions about hardware compatibilities, I’ll be able to give an opinion.

Thanks in advance

Thanks for your hint, I was there and saw the warnings.

This Radeon HD 6750m driver I found is apparently fullfilling the WDDM 2.0 specifications. The Issue I had was with the Radeon Software.
Regarding the Intel HD 3000, I saw a tutorial to use the driver for a HD 4000.
Maybe it resolves compatibility issues.
Whatever the results are, I’ll leave the update in case someone has the same troubles in the future.

Thanks :slight_smile:
