[LinuxBIOS] [PATCH] IDE legacy port access + UDMA/33 for 440BX boards

[Uwe Hermann]

See patch.

At the very least the IDE legacy port access must be enabled to be
able to use FILO. The rest is optional, but I see no reason to not
enable it per default.

should this maybe be a cmos option instead? Some old drives (being
present in old machines) might not work with the setting.

On the long run, yes. IMO we should automatically "extract" a CMOS
option out of these config variables. All of them make run-time
decisions in the code already -> perfect for CMOS options.

For now I'd like to commit as is, there's no CMOS support on 440BX
boards anyway at the moment, and ide_legacy_enable = 1 is really needed
to be able to use FILO.

Uwe.

Updated patch. It enableѕ legacy I/O port access, but disables
UDMA/33 per default as we don't know if the user's devices support it.
