Can't enter Setup.

I recently found a motherboard, a processor, a CPU fan, a hard drive, and a CD drive in my basement in my piles of computer misc. So built a computer/. When I fire it up, however, it asks if I want to enter Setup by pressing delete. I can press it once, press it multiple times, or mash the button, but no matter what it will ignore me.

It will then try to boot, but encounters a problem or two.

After the No Setup issue, it will then proceed to do the EXACT FOLLOWING (Note: any paranthesis means a comment):

Sec Master Drive - ATAPI Incompatible
Sec Slave Drive - ATAPI Incompatible
Press F1 to Resume

(Doesn't matter if the drives are attached to the primary or secondary IDE ports. Continuing, I then press F1)

[BIG LIST OF COMPONENTS IS DISPLAYED]

(then the following after the list)

RPL-ROM-ADR: 0007 - 950D - 6521
RPL-ROM-IRQ: 3
RPL-ROM-PIO: D400

RPL-ROM-FFC: (Runs thru the #s 1-5 every second. IE: 1, 2, 3, 4, 5)

BOOT Failure

Insert BOOT Diskette into Drive A:
Press any key when ready.

(I don't have a boot disk, so I press any key anyway.)

Searching for BOOT record from floppy..Not Found
Searching for BOOT record from SCSI.(Scuzzy).No Found
Searching for BOOT record from network..OK (It's not connected to any Internet whatsoever so I would think an OK here is impossible...)

I can't find the motherboard's name anywhere on it, but there is a big copper heatsink/disipator with the name "Amptron" on it. Only signifigant name I could find.

Is it an HDD problem, a cable problem, or an IDE controller problem? First time I've encountered this problem with a computer before.
