I have Toshiba Portege M400 Tablet PC with Intel 82573L Gigabit Ethernet Controller. It works fine with Windows, but in Ubuntu it doesn't work!
During startup CMOS shows the following:
PXE-E05 error, LAN Adapter configuration not initialized, Boot Agent cannot continue.
I figured out that it was due to NVM Checksum error, and I tried to flash EEPROM using Intel Boot Utility with no success. Flashing EEPROM always returned the following error:
PXE not flashed on port 1, Firmware not present.
I restored to Kernel to edit driver files and bypass NVM Checksum error again to lure without any fruitful outcome.
Here are some terminal output:
$ lspci -v | grep 82573L 02:00.0 Ethernet controller: Intel Corporation 82573L Gigabit Ethernet Controller $ ifconfig -a just listed wlan0 only
