Promise PDC20378 PATA support?

Promise PDC20378 PATA support?

[Dan Hopper]

Hi,

Has anyone had any luck getting PATA working on Promise PDC20378
controllers in a 2.6.x kernel?  As far as I can determine from
looking at the drivers and at 2-month old postings to linux-kernel,
the sata_promise driver only handles the two SATA ports and not the
PATA port.  The Promise-supplied TX2plus driver works (with PATA
support) for 2.4.x but hasn't been updated for 2.6.x.

I fear the answer is still no, but I hate being limited to only 4
PATA devices when I've got 5 sitting in there :)

Thanks,
Dan Hopper

If this is the controller that appears on motherboards like the MSI KT4 Ultra 
(Via KT400 chipset) then the PATA port works just fine in 2.4.x (x >= 22)

I'll have a dig in dmesg when I get home and find the relevant lines.

Mark.
