Very simple to get into the guts here; all I did was enable IPMI in the BIOS and SSH into the BMC's IP address... boom, root.

Here's a compressed ls -alR on the root filesystem for now... I've got a pile of notes on this... so little time, so many BMCs.

Some commands and their output.

And here's the dmesg output - the first part is lost due to buffer limitations.
