Just for the records:
linux-2.6.18 does not support the PATA of the PDC20775 (Promise SATA II 300 TX2plus) yet. This Controller is a 1xPATA and 2xSATA combo PCI card.
The SATA works right out of the box, but for PATA you need to apply the following patch: http://dev.gentoo.org/~dsd/genpatches/trunk/2.6.18/4110_promise-pdc2037x.pat...
Thanks Clemens!, this explains my lack of success with the PDC20378. Jeff Garzik (who apparently heads work on libata) assured me that PATA support for sata_promise is not in 2.6.18. The page above confirms that there is just *no* PATA support for the PDC2037X in 2.6.18. So my remaining question is, being unfamiliar with kernel hacking should I just apply a sort of rejmerge approach?: a) open linux-2.6.18/drivers/scsi/libata-core.c in emacs b) substitute the patch (indicated as lines preceded by +++) for lines to be removed (indicated as preceded by ---) c) recompile the kernel, redo grub, and d) reboot? --theo
