IDE Problem on ASRock K10N78

I recently replaced the motherboard in my raid 5 server (Gigabyte 570 SLI) with an ASRock K10N78. The rest of my system is as follows
AMD Sepron 1.8 GHz
2 x 2 GB DDR2 Ram
1 Maxtor 40 GB IDE HD (Windows XP Pro SP3)
NVRaid 5 array (3 x Seagate 320 GB, 1 x WD 300 GB, 2 x 500 GB WD) for about 1450 GB
550 Watt PS
Video is onboard Gforce 8200

I started by mounting the motherboard in my case and inserting the CPU and Ram. I booted to BIOS to ensue both passed the initial tests, which they did. Then I hooked up the 40 GB IDE drive (jumpers at CS) and booted to BIOS. This is where my problems began. BIOS saw the drive as a Iaxtkr 6A000HO with a capacity of 7.9 GB. I removed the hard drive and checked it on another computer to ensure it was working. I tried 2 other IDE hard drives on the ASRock motherboard, a 40 GB Western digital and a 80 GB Maxtor. Both are working drives but the BIOS sees them as Iaxtkr drives with a 7.9 GB capacity. I tried using different jumper setting on the HD, and changing the IDE cable but neither worked. The Maxtor 40 GB was bought new about 2 years ago for this server and the Maxtor 40 GB is about 2.5 years old. I tested my PS voltages and used a different power supply with the same results. Finally I attached an IDE CD-Rom as a slave and the Maxtor 40 GB as the master to try and reinstall windows XP. BIOS sees the CD-ROM as a tape drive and will not allow me to move it into the first boot priority position.

Finally I tried to test my raid. It is a non bootable 6 disk SATA raid 5 using NVraid. I hooked the drives and entered BIOS. When the SATA drives are in IDE mode in BIOS it shows the drives on SATA ports 1-4 correctly. However it does not show ports 5 or 6 (They arnt blank, there is no entry for ports 5-6, only 1-4). I changed the SATA mode to raid and rebooted. I was able to enter NVRaid Bios and view my array which it lists correctly and as healthy.

In conclusions this motherboard recognizes my sata raid array correctly but will not recognize any of 3 working IDE hard drives and it sees my CD-ROM drives as tape drives. I cannot boot to windows or even boot the windows install disk, I can only enter BIOS. I know the IDE hard drives work correctly and i have tested the memory and the power supply. These are not 5 or 6 year old IDE hard drives, the Maxtor was bought new for this particular system. I had to get an IDE for the OS because I was out of SATA ports. Does anyone have any suggestions?

Well, it sounds like it's missing the upper bits of the 16-bit IDE interface. Or at least missing one of the bits. You said that you swapped the cable. Have you checked the connector on the mobo for missing/bent pins?

Otherwise, I would say that the mobo is just defective, sorry.

I swapped the original IDE cable that worked on the previous motherboard with the IDE cable included in the new motherboard. I looked at the connector and there are no missing or bent pins.

My motherboard uses BIOS verison 1.5, which is the latest on the ASRock website. The original in 1.0 so I would assume if it was a BIOS bug it would have been found by now.

Here is what BIOS says under advanced setting for the Hard Drive:
Device: Hard Drive
Vendor: Iaxtkr 6A000H0
Size: 7.9 GB
LBA Mode: Supported
Black Mode: 16 Sectors
PIO Mode: 4
ASync DMA: Multiword DMA-2
Ultra DMA: Ultra DMA-6
S.M.A.R.T.: Supported

And these are the setting I can change, they are currently on default settings:
Type: Auto
LBA/Large Mode: Auto
Block (Mulitsector Transfer): Auto
PIO Mode: Auto
DMA Mode: Auto
SMART: Disabled
32 Bit transfer: Enabled

The last setting, 32 bit transfer, is one I have never seen in BIOS on another motherboard. I have tried it on enabled and disabled and it doesnt seem to change the way the disk is recognized.
