Anyone figure out how to successfully ghostcast a Lenovo SL500 at full speed?

I work for a school and have been having issues with the Lenovo SL500 notebook which has a Realtek pcie gbe family controller built onboard.

When running Ghostcast some lapops boot from the Ghost Solution Suite 2.0 Ghostcasting disc and register network speed at 10mbps which is too slow.  Other machines connect fine.  Not sure if this is a dos driver issue or bios issue.  I've even read that the laptop connects at different speeds depending on whether the AC Adaptor is plugged into the laptop at the time of booting, but that didn't really seem to matter.

These are decent laptops, it's just this one issue.  As a side note, when making the master boot image for these units you have to run Ghost with the -IB switch to grab all 4 boot record sectors which is unique with these laptops, most laptops and desktops only utilize 1 sector for the boot record instead of 4 so this messes Ghost up if you run without the switch.

If anyone has successfully created a Ghostcast boot disc can you post the .iso image somewhere so I could grab it?  That would be great!

Thanks,

Matt
