I tried to install FreeBSD on a Corebooted machine (using SeaBIOS payload) and it seems that the installer just won’t boot at all. With the 12.x version of the installer hangs just after ‘/boot/entropy size=0x1000’, and with the 11.x version it hangs after ‘Booting…’.

I tried to disable ACPI and enable Verbose in boot options, with similar result. Windows, Linux, and OpenBSD boot just fine on this machine.

It seems that it’s a graphic issue, I tried various combinations of Coreboot settings and here are the results :

GENERIC_LINEAR_FRAMEBUFFER (Linear “high-resolution” framebuffer) : no display at all

VGA_TEXT_FRAMEBUFFER (Legacy VGA text mode) : display, but with altered colors

Does someone have an idea on how to fix this ?

Thank you
