    摘要： A method is disclosed for securely updating system attributes of a client computer with a BIOS and includes signing a public key of a secure server with a private key of the BIOS prior to completion of manufacturing of the client computer to create an encrypted public key and embedded private key stored at the server. The method includes receiving at the server a request packet transmitted from the client computer requesting system attribute modification, encrypting the request packet to create an encrypted packet, and transmitting a return packet to client computer comprising the encrypted packet, the server's public key, and server instructions. The client computer decrypts the request packet using the server's public key and compares it to the original request packet, and if identical, executes the server instructions to modify the client computer's boot block to update client computer's system attributes.

    摘要： In a computer network including a plurality of interconnected computers, one of the computers being a sleeping computer in a power down state, the sleeping computer listening for a packet associated with the sleeping computer, a method and system of waking the sleeping computer from the computer network. An incoming packet of data is transmitted from one of the computers in the network to the sleeping computer. When the sleeping computer detects the incoming packet, it determines if the incoming packet contains a data sequence associated with the sleeping computer. Further, the sleeping computer compares a transit value in the incoming packet to a predetermined value stored at the sleeping computer. The transit value indicates how far the data packet has traveled through the network, indicating the approximate origin of the data packet. Knowing the approximate origin of the data packet allows the client system to identify if the data packet originated from an external network. The predetermined value represents an origin within the internal network. Accordingly, if the incoming packet matches the particular data sequence associated with the sleeping computer, and the transit value in the packet matches the predetermined value stored at the sleeping computer, then a signal is issued to wake the sleeping computer. Otherwise, the incoming packet is discarded and the sleeping computer is not awaken.

    摘要： A method for reducing the boot time for a computer includes: supplying power to the computer; disabling a plurality of input/output (I/O) devices coupled to the computer; performing a boot process for the computer; and placing the computer in a suspend to memory state before a user turns on the computer. The method reduces the boot time for a computer by placing the computer in a suspend to memory mode rather than completely shutting off the computer. In this manner, when a user of the computer pushes the power button, the computer wakes up from the suspend to memory mode instead of being required to perform the entire boot process. This significantly reduces the time required to make the computer available to the user, allowing the computer to function like an appliance.
