Hi there,
The patch that Arne Brutschy posted here (see http://www.cs.helsinki.fi/linux/linux-kernel/2003-22/0386.html) almost saved my life as it allowed me to understand why my 2.4.22 kernel didn't activate my Promise PDC20276 IDE controller properly.
(For the record, my kernel was displaying the following message at boot: PDC20276: neither IDE port enabled (BIOS) )
But this patch was only halfway satisfactory, as it enabled only one of my 2 controller channels.
So I did a quick-and-dirty hack that gives the following patch, that allows activation of both channels of my PDC20276.
This might help others encountering the same problem...
