![]() On the next boot of the system, there were no PXE messages from the network card and during bootup the e1000 linux driver only threw out the ominous message The EEPROM Checksum Is Not Valid without loading the network interface. When nothing happened after 5 minutes of waiting, I foolishly reset the system. The system wasn't reading anything from the disk, there was no progress message on the screen, just the general start-message of the firmware update tool. The instructions for flashing the firmware were relatively simple: Boot with a DOS bootdisk and execute eeupdate -nic=1 -d 82547EI.eepĪfter I pressed enter, nothing much happened. The lspci output on this board looks as ~]# lspci|grep EthernetĠ1:01.0 Ethernet controller: Intel Corporation 82547EI Gigabit Ethernet ControllerĠ3:02.0 Ethernet controller: Intel Corporation 82541GI Gigabit Ethernet ~]# The mainboard has two ethernet controllers, with the 82547EI one being the controller utilized by the management card. bin file and an accompanying eeupdate.exe file for flashing the firmware image. This firmware file came in the form of a. After contacting the Tyan support, we were offered a firmware file to flash into the network adapter activating the needed "management mode". In order to have the whole setup work, the IPMI management module needs support from the network interface in order to receive IP packets while the machine is powered off. The idea was to fit these machines with the Tyan m3289 server management card, an IPMI card allowing remotely powercycling of the machines and offering a serial console via the network. ![]() ![]() Some years back we bought quite some Tyan S5112 machines for. Maybe this gives other people some insight into valuable problem solving skills. ![]() NB: Instead of just giving a command by command description of what I did, I'll try explaining a bit more about the background and the process of fixing the problem at hand. This guide should serve as a good primer on reflashing your broken nic but probably needs to be adapted for your own use case. I had a similar problem in the past and as a favour for some friends of mine, I've written down a small description to restoring the ethernet firmware in these cards. As usual, lwn.net has a nice writeup of the issue including some background information. As most readers of this blog are probably aware, pre-releases of the Linux Kernel 2.6.27 are able to trash the NVRAM/EEPROM of certain Intel Network cards. ![]()
