Downtime today was a bit longer than expected. But we finally made some long outstanding changes. We are now using grub instead of lilo and with this change we enabled the serial console in the BIOS. So we now have the possibility to control the output from power-on until the OS is running. We also finally enabled the bonding of the two network cards we have so that we are now able to have an maximum output of 2GBit/s.
