Question : How to Open a Console Session (xterm)

I am trying to upgrade the bios on a HP T5545 thin client, I have downloaded the latest bin & tgz files to the usb drive, connected this to the HP thin client, but trying to follow the instructions, and it advises on opening a console session (xterm)
I am currently logging in as "administrator mode" on the thin client, looking at the control panel, but not having much luck.

Answer : How to Open a Console Session (xterm)

goto
Application->Accessories->Terminal.

Then login as super user
su for FC12.
sudo su for ubuntu.

Then type xterm to open xterminal.

however Terminal is also a console session you can give all the commands there also.
