I've been successfully imaging Dell pc's until Dell's new SX280 was
purchased at my location. Upon PXE boot I can lease an address, but
when the linux kernel is loaded I receive the error msg "Unable to
detect Network Card. Check Documentation for a list of supported
cards." The nic is a Broadcom NetExtreme 57xx Gigabit card. I assume
this is a linux driver problem since I can obtain an address upon
boot. Where can I find the linux drivers so I can do PXE imaging?
