P4C800-E MB and P-ATA Hard Drive issue

I am trying to connect a Seagate ST3200826A 200GB hard drive to my Asus P4C800-E motherboard. This is a known good hard drive, as it works fine with another machine. The same challenge occurs with an identical hard drive, as well as another older P-ATA hard drive.

I know that the 2 ide cables (ultra-dma cables) are working correctly, because my IDE DVD+-RW drive is detected on both IDE channels using both cables.

The 200GB Seagate hard drive is not detected by the bios, though I have tried jumpering it both as Master and Cable Select. I have tried it on both the Primary and Secondary IDE channels. There are no other devices connected on the same ribbon as the hard drive.

I disabled the onboard Promise controller because I do not have anything connected to the Promise port. I did, however, try connecting the hard drive to the Promise Controller with it configured to detect IDE. This, too, yielded no results.

I tried configuring the bios settings for "compatibility" mode for the IDE channels with only P-ATA support. Still no luck.

For all that I can tell, it appears that P-ATA hard drives will not work with this motherboard. I do not have a S-ATA hard drive to test on this computer.

Any suggestions?

Either try a BIOS update, using the BIOS update / flash tool, that came on the cd with the mobo. Or as a last resort, get a P ATA PCI controller card.

you have an ide hard drive. if your ide dvd drive works, the board supports ide. you have some other issue going on there. yank the dvd drive, and try the hd solo on both master and cs settings.
