Hi, We are having a problem with a couple of classrooms with Viglen Genie 644M machines. A number of the Viglen machines seem to be not switching on their ethernet controllers. We have checked the BIOS, ports,the switch and updated the BIOS with no results. Forcing boot from PXE and then cancelling it works some of the time on some machines but the problem doesn't seem consistent. Viglen are unsure as to what is causing it. Has anyone else had similar issues with these machines? We haven't seen any problems with the Dells or other manufacturers.
