For information, was having a similar issue with the intel drivers and sysprep images on a GX620.
deleting the "ich78id2.inf" and "ich78id2.cat" from the drivers folder before sysprep'ing the machine fixes the problem
if you have this problem and have already imaged it, boot to safe mode and delete these files from your drivers folder, 'uninstall' the ide controller, and re detect / manually install the driver from the "ich78ide.inf" file.
my 2p, hope that helps someone
