That's Because may be u are using a SATA/RAID controller for Which Windows XP doesnt come bundle with Driver's...
To Me, there are 2 way's
For the 1st one you can download the Drivers from here, *h10025.www1.hp.com/ewfrf/wc/softwa...535-1&lc=en&cc=us&dlc=&product=1817059&os=228
then put them on a floppy drive
Boot from Installation CD, Put the Floppy in the drive, and Press F6 when Windows Installation ask for a Third Party Hardware driver,

Now select the driver for ur device !!!!
Now the second Method and i think u may not have Floppy in that NoteBook

so, here is the option for u, Download the driver, Get ur self WinRAR and then use it to Extract or UnPack Driver in .inf type files, now Download N-Lite to Integrate the Driver in to ur Installation Disk, in that way u will not need a floppy drive !!!
Link = Guide how to use n-lite *www.nliteos.com/guide/ Note, Follow the Part which says how to Integrate Drivers,
P.S. Windows XP comes with Intel SATA controller driver bundled, u shouldnt have faced the issue in 1st place, wonder why u are facing it... From Where did u get the Windows Installation CD ??
