摘要： A memory access system for accessing a basic input output system (BIOS) program is provided. The memory access system includes a flash memory, a CPU, a peripheral component interconnect (PCI) slave, an address converter and a flash memory controller. The flash memory stores a number of BIOS data of the BIOS program, and each BIOS data corresponds to a default BIOS address and is allocated in a flash memory type BIOS address. The CPU delivers a BIOS access instruction. The BIOS access instruction corresponds to a default target address of the default BIOS addresses. After the PCI slave interprets the BIOS access instruction, the address converter converts the default target address into a flash memory type target address, which is one of the flash memory type BIOS address. The flash memory controller accesses the BIOS data allocated at the flash memory type target address accordingly.

摘要： A bus controller and a control method are used in a computer system. In a bus controller, a bus controller main circuit issues a first signal to the central processing unit in response to a bus configuration cycle for indicating the presence of a first-level bus that the first group of components is coupled to. A virtual bridge device issues a second signal to the central processing unit in response to the bus configuration cycle for indicating the presence of a second-level bus that the second group of components is coupled to. A path selection unit electrically connected to the first and second groups of components via the first-level and second-level buses, respectively, outputs a normal device select signal to one of the first-level and second-level buses while outputting an invalid device select signal to the other of the first-level and second-level buses according to address data of a transaction.

摘要： A method for determining an operating voltage of floating point error detection is implemented by a central processing unit (CPU) and a south bridge chipset. The CPU has a first output port connected to a test port of the south bridge. The test port is used to determine an operating voltage of the CPU. If the operating voltage of the CPU is greater than a predetermined value, the first output port is floating. If the operating voltage of the CPU is smaller than the predetermined value, the first output port is grounded. The method includes using a power supply and a resistor to provide a bias voltage and for measuring a voltage of the test port to determine the operating voltage of the CPU.

摘要： A method for accessing a memory of a computer system for BIOS codes optionally performs a detection procedure to realize a maximum memory burst read size of the memory according to a flag value upon the computer system is initialized. For example, the detection procedure is performed when the flag value is logic “1” and the detection procedure is not performed when the flag value is logic “0”. When the detection procedure is performed, read requests with sequentially reduced memory burst read sizes are asserted to the memory one by one until the maximum memory burst read size of the memory is realized. Then, the BIOS codes are read from the memory with the maximum memory burst read size.
