This forces SeaBIOS to see it as a PATA controller, but it's in SATA mode.

Kevin,

Is there an easy way to add SATA support to SeaBIOS?  It sounds like a
bit of work.  It looks like you could force the device to be in PATA
mode, but once it's booted that's not ideal.

Maybe there's another option we haven't thought of.

Thanks,
Myles

SeaBIOS only supports PATA mode.  To the best of my knowledge, filo
also only supports PATA mode drives (or SATA drives connected to a
PATA compatible controller).

I'm not against adding support, but I don't have the knowledge to do
it at this time.

The interesting thing is that filo supports this board even though it is in
SATA mode.

No problem.  I mostly wanted your opinion on the cleanest and easiest way
forward for this box.

If, with SATA mode you mean AHCI, you are right.
