   Try pulling the graphics card.  This *should* trick the thing
into going past this error.  And, yes, 262 is "Keyboard not detected

   The machine wants full modem controls from the serial
device.  Typically, what one will see if the modem signals
aren't properly done is that you'll see the boot-time output
