The Accelerated Graphics Port (AGP) is a new port on the Host-To-PCI bridge device that supports an AGP port. The main purpose of the AGP port is to provide fast access to system memory. The AGP port can be used either as fast PCI port (32-bits at 66MHz vs. 32-bits at 33MHz) or as an AGP port which supports 2x data-rate, a read queue, and side band addressing. When the 2x-data rate is used the port can transmit data at 533MB/sec (66. 6*2*4). The read-queue can be used to pipeline reads ­ removing the effects of the reads-latency. Side band addressing can be used to transmit the data address on a separate line in order to speed up the transaction. 1-6 6EA 2. SPECIFICATION 2. 1.

[. . . ] 1 2 3 Function +5V SB GND Signal t SB-LINK : For PCI Audio / Sound Card use only Pin No. The CMOS SRAM is used for keeping the information of system configuration, so the system can automatically boot OS every time. Since the lifetime of internal battery is 5 years, the user can change a new Battery to replace old one after it cannot work. M Danger of explosion if battery is incorrectly replaced. [. . . ]
