At Device Manager > IDE ATA/ATAPI Controllers, what's the device name listed. Also, what driver is installed?

According to what I found out it should say: Intel(R) ESB2 SATA AHCI Controller

You only need AHCI enabled, not IDE nor RAID. This should be set via the BIOS. At SATA Mode what options are there? On most motherboards it's three options: IDE, AHCI, RAID. What does your BIOS show exactly?

This is a strange configuration but then again I don't have workstation-grade hardware knowledge so it makes sense for there to be differences. My guess is that Seperate IDE is the normall IDE mode, Combined IDE is the legacy/compatibility/PATA IDE mode found on older hardware. It makes sense for that to not load the OS in that case. For best performance you need the RAID + AHCI option indeed.

The description says that both RAID and AHCI oROMs execute so I guess this BIOS also includes a dedicated AHCI oROM. Maybe that one needs to be updated to support bigger HDDs. Since you cannot edit HP bioses though that's not really possible.

i suggest you try the latest Intel RST drivers in case that's a software problem. It seems that the latest for Intel ESB2 are v10.1.0.1008 and can be downloaded from Fernando's driver thread HERE. Update both the AHCI and RAID drivers to v10.1.0.1008 and check if that fixes the problem.

The driver you mentioned is older. Download version 10.1.0.1008 from HERE.

Update Storage Manager with file iaStor.inf and ATA/ATAPI Controller with file iaAHCI.inf

Afterwards, both devices should report driver v10.1.0.1008.

Update Storage Manager with file iaStor.inf and ATA/ATAPI Controller with file iaAHCI.inf.

I doubt, that the latter will work, because the listed "Standard Dual Channel PCI IDE Controller" is an IDE one and not compatible with any Intel AHCI driver.

Maybe but since I have not properly understood what devices are shown inside Device Manager, this is my best guess. At BIOS he set RAID + AHCI mode so there has to be an AHCI device. Could it be possible that in such workstations the RAID device is used for AHCI as well?

I don't know, but a picture which shows device manager with the different devices should help.

This is what Devilman had written:

Under IDE ATA/ATAPI it shows only ATA Channel or controller Standard PCI IDE, while under archive controller in says Intel(R) ESB2 SATA RAID Controller

Indeed the actual VEN_ID and DEV_ID are needed. I checked the manuals for this model which can be found HERE, and found the "Setting-up RAID Manual" which shows the BIOS options he is seeing. Direct link:

@ Devilman:

Thanks for the details of your on-board IDE Controller, which verify, that
a) it is an Intel one and
b) you will not be able to use any Intel AHCI driver with it.

The full device name is Intel 631xESB/6321ESB Ultra ATA Storage Controller - 269E and it's not AHCI but IDE. So, this motherboard uses RAID for AHCI capabilities when an actual array is not built.

Did you update the RAID driver to the latest v10.1.0.1008? Select iaStor.inf file when installing via the Have Disk Method.

Btw, are you running a 32-bit (x86) operating system? From the picture it looks like Windows 7.
