I never needed to make changes to vga.dat on my E3845 system. The vga.dat was taken from the FSP package the same as you. The coreboot version that I used was 4.7.

Hi Jose,
Thanks for a quick response
Enabled framebuffer in Config as given in inserted picture and am using uefipayload but not seabios
[image.png]
To add more to this
MinnowMax + VGA -> Display is seen BayleyBay + VGA -> Display is not seen
Does the FSP-master\FSP-master\BayTrailFspBinPkg\Vbios\vga.dat needs any change?
Do you think in the hardware the DDI0, DDI1 pins and clk/data can have an impact and needs to be measured

Hello Ranga:
If you are using tianocore as payload you should choose vesa framebuffer option and text mode in seabios JT

Do i need to configure any setting in \FSP-master\FSP-master\BayTrailFspBinPkg\Vbios\vga.bsf file from BCT?
Please let me know what could be the reason and if anyone has seen such behavior earlier
Best Regards Ranga
