| [ 24. A method for operating a computer system, said method comprising:
inserting an attached computer module (“ACM”) into a bay of a console in a modular computer system, the console comprising
a first low voltage differential signal (LVDS) channel comprising two unidirectional serial channels that transmit encoded
data of Peripheral Component Interconnect (PCI) bus transaction in opposite directions; said ACM comprising
a microprocessor unit coupled to a mass memory storage device;
a north bridge to communicate address and data bits of PCI bus transaction in serial form, said north bridge directly coupled
to said microprocessor unit;
a main memory coupled to said microprocessor unit through said north bridge; and
a second LVDS channel comprising two unidirectional serial channels that transmit data in opposite directions, said second
LVDS channel extending from said north bridge to convey said address and data bits of PCI bus transaction in serial form;
applying power to said computer system and said ACM to execute a security program, said security program being stored in said
mass memory storage device; and
prompting for a user password from a user on a LCD display coupled to the console. ]
