Abstract: A built-in redundancy analyzer and a redundancy analysis method thereof for a chip having a plurality of repairable memories are provided. The method includes the following steps. First, the identification code of a repairable memory containing a fault (“fault memory” for short) is identified and a parameter is provided according to the identification code. The parameter includes the length of row address, the length of column address, the length of word, the number of redundancy rows, and the number of redundancy columns of the fault memory. Since the parameter of every individual repairable memory is different, the fault location is converted into a general format according to the parameter for easier processing. A redundancy analysis is then performed according to the parameter and the converted fault location, and the analysis result is converted from the general format to the format of the fault memory and output to the fault memory.

Abstract: The invention provides a connection structure installed in a data processing apparatus. The data processing apparatus includes a keyboard and a base. The keyboard includes a bottom. The base includes a top plate. The connection structure connects the bottom and the top plate. The connection structure includes a mounted boss and a mounting hole. The mounted boss is disposed on the bottom of the keyboard. The mounted boss includes a groove. The mounting hole is disposed on the top plate of the base. The mounting hole includes a protrusion. When the bottom of the keyboard is assembled to the top of the base, the mounted boss would fit into the mounting hole, such that the protrusion is locked with the groove.

Abstract: A system for monitoring BIOS (Basic Input/Output System) messages of remote computers by a local server includes: the local server (1) for executing a monitoring program (11) to send requests for acquiring BIOS messages, and receive and display the BIOS messages; the remote computers (2), each remote computer executing a POST (Power On Self Test) program for outputting the BIOS messages, receiving a request for acquiring the BIOS messages from the local server, and transmitting the BIOS messages to the local server; and a network (3) for connecting the local server with the remote computers. Each remote computer includes a CPU (Central Processing Unit) (21) for executing the POST program and outputting the BIOS messages, a remote control card (22) for detecting and capturing the BIOS messages, and a PCI (Peripheral Component Interconnect) bus (23) for connecting the CPU with the remote control card. Related methods are also provided.
