Page 40 of manual: choose Onboard IDE or FastTrak ATA-100/RAID.
OnboardIDE means Serverworks, FastTrak means PDC20265.
BIOS settings for primary/secondary disk relate to the Serverworks
channels.

Page 11: Primary/secondary IDE: VIA, RAID primary/secondary: PDC.
Page 33: Primary/secondary IDE settings relate to the VIA.

Page 5: Integrated PCI IDE (it talks about i845 internal) +
integrated IDE RAID (20267, so no relevance here). Page 28:
primary/secondary disables i845, not PDC.

Serverworks, with IDE. Serverworks IDE is primary.
RAID is 20267, so no relevance. Manual not available yet.

VIA onboard, HPT370 RAID. Connectors of RAID marked IDE3/IDE4.

8k3a has no RAID. 8k3a+ has PDC20267. Primary IDE is from VIA,
RAID is additional...

Manual unavailable from the web (404 Page not found after clicking
on manual). Picture shows IDE #1/IDE #2 (VIA) and IDE RAID #1/#2.
Besides that it has PDC20267, so it has no relevance to this discussion.

Manual page #10: IDE1/IDE2 for VIA, IDE RAID #1/#2 for PDC.
Page 14: 2 IDE bus master interfaces support UDMA/100 (listed first),
2 IDE RAID connectors (listed later). Page 49: IDE primary/secondary
settings relate to the VIA.

I did my homework. I still believe that there is NO MAINBOARD with
PDC20265, and without southbridge IDE - be it VIA, SiS, Intel or Nvidia.
All motherboards you listed have PDC (or HPT) as an additional controller,
and manual always refers to southbridge as IDE#1/IDE#2, while PDC
is referred as IDE RAID#1/#2, or even as IDE#3/IDE#4.

If you tried to prove that PDC20265 should never be ide0/ide1, then
we are on the same boat.
