The seabios_grubfirst images provides the same functionality than the
GRUB images, but instead of having GRUB being loaded directly by
Coreboot, Coreboot loads SeaBIOS which then loads GRUB.
These images probably exist to enable end users to try it to workaround
potential compatibility issues between the OS and GRUB with the GRUB
image as we have a BIOS implementation being loaded.
While this looks useful, it also makes things more complicated:
- It increase the number of images to choose from, and it's
complicated to explain the difference between grub and
seabios_grubfirst to end users.
For instance for the "x200_8mb", users need to choose between 2 GPU
modes (corebootfb, or txtmode) and 12 keyboard layouts. So having to
choose between 2 payloads instead of 3 with one difference that is
hard to understand makes things easier.
- It makes testing more complicated as we have one more payload to
test and we also need to make sure to always differenciate both
images in bug reports, documentation, etc.
And if issues arise from this change in the future, we could work with
upstream to fix them and/or replace the grub images with
'seabios_grubfirst' while keeping the 'grub' name to avoid
complicating things by having two main payloads with identical
features.
