There are actually two parts to this. You need to be able to function without a daemon as in single user mode or sysinstall. You also need to be able to work in the polling mode the debugger uses. > i think i see where you are going. you are probably thinking about > some sort of lights-out management where you use only network > connection to control box remotely, a-la pc-weasel and eric cards. am > i close? I'm primairly intrested in solving the problem of machines with a AT keyboard controller (which currently attached non-existant keyboards to allow hot-pluging) and a USB keyboard. The second case I'm intrested in is a LOM card. In one case I've seen one present the keyboard as a USB keyboard which means you need to support two USB keyboards. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
