Problem with IDE device detection on Asus P5AD2

(This is really long but please bear with me)

Last weekend I bought all the components to build a computer and have put them together, and everything was working fine, up to the point of detecting the IDE devices.  No matter what I try, I cannot get the computer to reliably detect and use the devices without giving an error.

I am trying to connect an optical drive (Creative) and a blank HDD (Seagate), so that I can boot up from the Windows XP CD in the optical drive to install the OS on my new system.

The motherboard is an ASUS P5AD2 Premium  
There was an issue with the Intel ICH6 previously in these motherboards, but I have confirmed that this has been fixed for my board.

It has a primary IDE connector and then two other separate IDE connectors for use in a RAID – but by default these are set to normal IDE and I have confirmed this in the BIOS setup.  The manual says that these can be used for normal IDE devices.
There is a limitation with the motherboard in that I have to plug the optical drive into the primary IDE or it cannot be used as a boot drive (which I need to install the OS).  The computer will detect the optical drive in the primary IDE, but will either not detect any other HDDs or it will detect them but give the error that they are "ATAPI Incompatible".  It only seems to detect the CD-ROM if I use the asus cable labelled "CD-ROM" and not if I use the HDD cable that has the differentiated plugs - blue, grey and black.

I know that each IDE channel has a master and slave (grey for master, black for slave), and that you cannot have two masters or two slaves on a channel.  I also know that I have to set the jumper on the devices correctly as either master or slave (ignoring cable select for the moment).  This is not the problem.

On one occasion only after trying repeated combinations with the IDE connectors I succeeded in getting the CD-ROM booted from the Windows XP disk and it started installing on the blank HDD, but after the hard disk formatting stage, the XP installation kept going back to the same screen again and again (asking if I wanted to install windows on the same partition – I pressed “c” to continue and then after loading all the drivers and files it goes back to the same screen asking if I want to continue by installing Windows on the partition.. again and again ).  After much searching the web I discovered that this was because the HDD was greater than 137Gb.  Apparently the HDD must be less than that figure for XP to install correctly.

So I then bought a SATA HDD (120Gb only) and connected it, thinking that this would be easier than the PATA drive, but it too is not recognized.  At one stage it made repeated clicking noises but that was all.

I have tried resetting the BIOS to defaults, but this has not improved the problem.

Does anyone have any ideas?  Any help would be greatly appreciated.

You need to install the riad drivers when loading windows XP hit F6 and add drivers give me a few minutes and I will find your drivers.

as far as the SATA HDD , if it's not recognized and is making loud repeated clicking noises I would probably return it (Test it on another PC if possible 1st) Have you made sure your SATA is enabled in the bios?  Is the ITE8212F Controller set to  IDE mode? and Silicon Image Controller set to SATA  mode for the SATA to work without raid? last but not least is  Report IDE error enabled to see if it's reporting anything to you reguarding the trouble your having?

I'm reading from the manual just to shoot out some ideas

Dynamic1Commented: This is the silicon image raid driver. Here are all of your other drivers. Press F6 to load mass storage driver when it asks usually a few minutes or less into install. Load the silicon Image mass storage driver weather you are running in raid or not you need this driver. Enjoy your new system looks like a nice board.

Why do you need to boot from the disk drive in order to install the OS?  Could you not start it with a floppy including drivers for it?  An XP rescue disk made on another machine may suffice.  [If no note made of other comments it is because none are posted yet; last time three wedged in front later.]
you should have all raid options in the bios changed to either IDE mode or whatever the manual says since your not using raid at all.
If he is using a Sata drive it has to go on a raid channel on that board.
By the way, it sounds like you have two different cables - the one designated CDROM is a 40-wire cable, and the other one is an 80-wire cable.  You should be able to hook up the hard drive and CDROM on the 40-wire cable, but the 80-wire cable can only work with hard drives.
Also Andrew I do not think the 236GB thing is a problem I have a 200GB as a master in one of my systems no problems. But I do know ASUS and they usually make it so you have to load several Drivers on there high end boards for the HDDs to work example Windows XP on P4C800 Deluxe you have to load 2 Sata Drivers or no go.
Whoops 136GB :>)
About jumpering:
Cable Select (CS) is one method of determining master and slave relationship on an IDE channel. To use CS, the IDE controller must understand it, you should have a proper cable AND your drives MUST be jumpered for CS. The end connector is for the master drive (or single), the middle connector is for the slave.

Having the CD unit and the master HD on the same channel (primary) shouldn't be a problem, unless ASUS has chosen to incorporate a non-standard IDE controller on this MB.

Check jumpering and that the IDE cable is the right way around (the correct end goes to the MB).
I was just reading off the manual for the settings. you can completly remove the raid function . That all I was refering to. If the drive is detected in the XP setup then he wont need to d/l and use the F6 function to install the raid drivers. XP does have default ones. (Especially if your using the latest XP setup cd w/ SP1 included)

Where is it not recognized ? in the Bios or windows setup?
DEW I know most asus boards with multiple raid controllers need that driver for SATA operation P4C800 DELUXE was one example even with XP SP1. Mabye they have changed now. I am not too familiar with Intels newest chipset yet waiting for the bugs to be worked out. And the prescott is real unimpressive to me so far as the northwood outperforms it and runs cooler. I went crazy with the P4C800 Deluxe when it came out trying to get it to work. Soultion was to load both raid drivers under mass storage controllers. Then it was fine. And I was only running a single drive.
Just done one almost identical to this:

First in the BIOS there is a setting por the Promise SATA controller - The choice is RAID or IDE. - If you only have one drive installed, or if you are not planning  on using RAID set it to IDE.

Second - On the motherboard CD drivers disk there is a folder for drivers. In the promise ATA folder I seem to remember there were 2 sum folders one for RAID and one for IDE. In each of these folders there is a folder for each operating system, however there is also a floppy driver disk maker! Use this to make a driver floppy disc (it's the same floppy for all proposed OSes as you'll see once you've created it).

Once you've started to boot from the XP CD, insert the floppy, and press F6 when asked if you are wanting to install any other drivers.

Finally, it then asks you to identify any additional drives that you want to add a little later on in the boot process. Check that these match what you think should be there.
