Thanks for the pointer.
I start wondering if the mainboard / BIOS vendors stop supporting
such older hardware, if such support could be re-added in Linux?
OK, obviously not for the boot device, but...
In U-Boot we have an x86 emulator to be able to initialize the
on-board BIOS on (at least some) graphics cards so you can use these
on ARM or Power architecture systems. Do we really have to add
similar stuff to Linux to support legacy hardware?
Would that even work?
Best regards,
Wolfgang Denk
