The network controller used on these machines has a 2 stage power supply. The 1st stage initialises at switch on and the 2nd stage at about 75% of the boot sequence, if the 2nd stage fails then you will get the "controller unavailable" message. The answer is to replace the internal power supply for the network controller.

This may sound like a joke but its not. While the 5030 is still booting and says 75% on the screen just unplug the power cord and wait a few seconds then plug it back in. It should boot then. If not, try it a couple more times.
