THIS DOES NOT WORK… .e4 does not recommend attempting to hack your Switchvox.
As your Switchvox is booting (just after you have turned it on) press the [space bar] when you see the GNU GRUB boot screen. The countdown timer should stop.
Press a to add a kernal argument.
it should say something similar to : grub append > ro root=/dev/VolGroup00/LogVol00
Add a space and the word single to the end so it should look similar to
grub append > ro root=/dev/VolGroup00/LogVol00 single
Now press enter. The system should boot and display a prompt like sh-3.1.
Start the network service.
At the prompt sh-3.1# type : service network start [enter].
It should say
Bringing up loopback interface [OK]
Bringing up interface eth0 [OK]
