P4DC6+ BIOS and SATA Question

I am running BIOS rev 1.2c on the P4DC6+. I just installed 2 new
Hitachi 7K250 160GB SATA drives, attached to a Promise TX2Plus
controller card. The controller supports 2 parallel ATA drives in
addition to 2 SATA drives. I have two Western Digital UDMA5 drives
attached to the Parallel interface.

My problem is that the Promise card reports all 4 drives as UDMA5 during
the boot process, instead of showing the 2 Hitachis as "Serial ATA".
The implication (verified by SiSoft Sandra) is that the new drives are
running at 2/3 of their rated speed (100 mbps vs. 150).

Could this be a motherboard BIOS issue? I am hesitant to install the
most recent BIOS (1.3) until I know whether it should fix the problem or
not.

Thanks...

It has nothing to do with the BIOS. I'm not sure what is causing this
problem, but I do know that the motherboard has no effect at all on how
the Promise card identifies drives. You could install that card on ANY
motherboard, and it would behave the same way, from a BIOS standpoint...
