XP is a lot more sensitive to hardware changes than was win98. however, it
does have a way to handle such things. You need to preform a "repair" also
called a "repair installation". This is similar to a full installation, but
does not reformat the disk, so your personal files are preserved, as are
most settings. In order to do a repair you need a real XP CDROM, not an OEM
version, and definitely not a "restoration CD".
Early during the repair a message will flsh brief near the bottom of the
screen asking if you have any third party drivers. It may mention SCSI and
RAID. Quickly hit F6, then insert a floppy with the drivers when requested.
Note that the drivers must be on a floppy, not on a CD or other medium; that
is a limitation of the XP installation routines.
Here are some links about doing a repair:

But, you are not done. The repair should get the controller card and
associated disk recognized by XP. But to use the full 160 Gig in XP, you
also need to apply SP-1. Check to see whether your XP CDROM already has
SP-1; maybe it does, if you are lucky. Finally, you need to activate LBA-48
in XP. See the following link:
