The security chip is a Dallas Semiconductor security key, the Roms are
programmed to look for this (I believe it is in the BIOS of the system.
I had played around once or twice with trying to crack this so that I could
upgrade a 6000 mega touch. Also some of the upgrades are limited by the
boards them self. Example my 6000 can not go up any more or else it would
require a CD-Rom (double speed only to work) and or a HD.
I have not figured out how to interpret the Roms as to which key is used.
