"Prior to SP2 Windows XP does not support PCI-Express Video cards during the install, at least not the more recent ones, which is what your Inspiron has. You have to use a Windows XP disk that includes SP2 to install."

is this so??

Possibly.  Sounds like a good explaination.
 
Slipstream:
A technique of extracting the contents of the disk into a folder, adding new content to the install files, and then burning the contents back onto a disk
 
Basically, you can make your own XP install disk using the original disk but make this new disk have more items than the original.  You can add your chipset drivers to it including your SATA drivers -- which I am sure you will need in order for the install to work (you will find this out further in the install).  You could also add the SP2 to the slipstream disk.
 
I have never done a slipstream, so someone else will have to give you guidance.  Or you could do a search on the subject.  I read a guide once which seemed pretty complete and included all the instructions and links to software you need in order to do the process.  But I don't know where it is now.
