I have tried ALIX-1 and 2
here is an example:
PC Engines ALIX.3 v0.99h
640 KB Base Memory
261120 KB Extended Memory
Waiting for HDD ...
01F0 Master 848A SanDisk SDCFH2-002G
Phys C/H/S 3970/16/63 Log C/H/S 992/64/63
any key I hit, it echoes as # and is ignored.
at this point the kernel is not yet involved, so having vga+kb support
is not the reason, though I will try out the alix-3, which has vga support, and
a different BIOS soon.
