#87 20211122: No onboard graphics for Gigabyte GA-G41M-ES2L

In trying out the 20211122 testing on my Gigabyte GA-G41M-ES2L I have tried both seabios_grubfirst_ga-g41m-es2l_libgfxinit_txtmode_usqwerty.rom and seabios_withgrub_ga-g41m-es2l_libgfxinit_txtmode_usqwerty.rom.

In both cases the onboard graphics don't work until the kernel starts and initializes that hardware.

I had previously used 20160907 and was able to see the built-in GRUB menu from the libreboot GRUB payload on boot, before the operating system started, which made it possible to boot from external media and adjust settings to specify fb=false on the linux kernel parameters in GRUB to boot the Trisquel net installer.

In trying a PCI Express graphics card I find that the expected GRUB menu from libreboot does show up, so this is limited to only using the onboard graphics which was not possible in 20160907 as the PCI Express slots don't work in that version.

Having working PCI Express slots in 20211122 is probably overall probably an improvement because it makes HDMI possible and I suppose I could live with that but it would be nice if both could be used.
