Im trying to create a USB Network boot package to ghostcast a set of laptops, I have created and used network boot packages on our USB sticks hundreds of times for a number of computers but our laptops don't seem to like it! They all have Intel 82577lc NICS and I have added the 82577lc driver to the boot wizard when created, I have also tried universal drivers etc......

The laptop will boot the usb and stay on the ghost Dos screen for a couple of minutes before shutting down.
