You should know by now that you need ram to boot any type of computer, when you turn on that switch the eeprom(PROM) looks in Ram to find out if it is gonna warm boot or cold boot... and if there is no ram to search it gets locked up in a loop! I acctually think the address is something like hx00056...something like it.
