Abstract: Method and apparatus for dynamically connecting a system under test (“SUT”) to and disconnecting an SUT from a private virtual local area network (“VLAN”) in a computer manufacturing environment are described. In a preferred embodiment, each time an SUT disposed in a burn rack boots up, a VLAN-capable switch (hereinafter “CAT”) connected thereto checks the media access control (“MAC”) address of the SUT against a MAC address-to-VLAN correlation table (“MAC-VLAN table”). If the SUT's MAC address is not listed in the MAC-VLAN table, the CAT connects the SUT to a predefined default VLAN; i.e., the manufacturer's main manufacturing network. If the SUT's MAC address is included in the MAC-VLAN table, there is a private VLAN associated with the SUT and the CAT connects the SUT to the associated VLAN in a conventional fashion, at which point custom configuration can be performed as needed on the private VLAN.

Abstract: A method and system for automated support in a computer system. The computer system has a service button, and pressing of the service button causes a bit to be set in a register in the chip set. Setting of the bit generates an interrupt signal that is received and processed in a manner dependent on whether the computer system is in a booting state or a non-booting state. If the computer system is in a booting state, the bit is checked at a predetermined point in the booting sequence, and if set, a service application is initiated at that time. If the computer is not in a booting state, a second interrupt is generated, causing the service application to be initiated. A timer is initiated substantially with pressing of the service button, and if the service application reaches a predetermined point before the timer reaches a predetermined value, it will clear the timer. If not, the system will follow a predetermined reboot protocol.
