Bios doesn't see hard drives

I just finished building 6 work stations for a new business i'm starting, so I'm reasonably competent at building computers.  I'm totally stumped building the server.  I'm using an Asus K8N-DL mobo with dual opteron 280's, 2g's of ram per CPU, and dual Western Digital  Raptor 150g SATA hard drives, with a PC Power and Cooling 850W  power supply.  On booting up I get the normal post beep and holding down the delete key it says its entering set-up, but never gets there.  If I hold down the tab key, it boots to the post screen and shows its seeing the dual opterons and all the memory, but shows no hard drives.  The case is hot-swapable, so I have pulled out both drives and can hear them quietly spinning.  I 've tried resetting the CMOS per the manual instructions and solved nothing.  I've tried unplugging the SATA drives and plugging in an old, but working, IDE drive and it doesn't see it either. The green power LED is glowing. but the red HDD LED is not.  I've checked the ASUS website and the board has the latest BIOS version. Help! Also, when I'm in the post screen, I get no response if I press delete to enter set-up.  I hope it's just something dumb, because I really need to get this maching working.

Sometime when you hit the DEL key to enter setup, it will wait for the HDD detection time-out. some BIOS waits until about 30 secs for the time-out before it gets to the BIOS menu. Try to wait a little longer >30 secs and see what happens.

Remove everything except the minimal to get the board running (1 CPU, 1 stick of RAM, try every slot, VGA). Then if the system boots up, add the other add-ons one by one until you have found what causes this.

<<holding down the delete key >> Don't. As soon as it says entering setup, release the key. If it can't find an IDE drive, it is probably faulty. <<6 work stations for a new business i'm starting, so I'm reasonably competent at building computers>> Not necessarily, just a bit of luck so far. You may be correct, but we have no idea as to your qualifications re this statement.

A quick look at the spec says it uses Silicon Image (yuk) and nVidia sata controllers, so the sata is not (fully) integrated into the bios. This means several things. One it won't recognize the sata disks unless you hit <F6> when prompted and insert the sata drivers on floppy (which you prepared earlier from the mobo disk) and two, that it will be liable to data corruption if it is ever powered of without notice - i.e exposed to a power failure. If you get it working, buy a UPS.

Actually rindi had half the answer, but apparently credit can go only to one.  I finally got through early this morning PST to ASUS support.  Solving the boot to bio setup, involved removing one of the 2 sticks of ram for CPU 1, then disabling the Silicon graphics raid controller, then setting the proper raid setup.  The permanent fix is F6'ing during windows setup and installing the correct Nvidia raid drivers, which also was a problem.  The motherboard disc doesn't have the right driver Server 2003.  As soon as the Asus download server comes on line,  I should finally be able to get the sucker running.  Thanks for you help.

Thanks for the points, but you can split. Click the Help button right at the top of the page. Look at -

More than one Expert helped solve my problem. What do I do?

If you would like to split now, post a zero point question in Community Support asking for my answer to be unaccepted, and the question re-opened. Then you can split if you wish.
