Promise PDC20319 & Intel FWE6300ESB on PSCH-L: Which device?

Hi!

I have got no effective answer for my question from other lists including the original hardware manufacturer. This list is my last resort.

The main board's model name is PSCH-L from Asus. It glues two chips:

Promise PDC20319 controlling 4 SATA slots for hard disks. Intel FWE6300ESB controlling 2 SATA slots for hard disks.

The board also burns a firmware called FastTrak or FastBuild which manages the Promise chip I guess.

My problem is that I can't find the devices controlled by either of the two chips:

# fdisk /dev/sda 

Unable to open /dev/sda

Same to /dev/sdb, sdc, sdd, sde, etc...

Drivers "Promise SATA SX4" and "ata-piix/ICH" are compiled in the boot kernel. This is the excerpt from the output of dmesg:

"fdisk -l" lists nothing except /dev/hda1.

Where are the right /dev/ for these SATA disks? Your helps are much appreciated.
