I recently installed CentOS 5 on Dell PE 1750 server. I have noticed that the speed and duplex settings are 100 Half Duplex. I tried to change the duplex settings to full, but no success. I got the error message "Cannot get current device settings: Operation not supported". Does anyone else experience this issue?. Below is the error message and some more details about my box. Any help will be highly appreciated.
