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. 32bits 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. 1-5 Specification 2.

[. . . ] Note: It' s strongly recommended that set the system speed according to your hardware configuration: CPU, SDRAM, Cards, etc. 3. 6. CMOS RTC & ISA CFG CMOS SRAM The mainboard contains RTC & CMOS SRAM on board. They have a power supply from external battery to keep the DATA inviolate & effective. The RTC is a REAL-TIME CLOCK device, which provides the DATE & TIME to 3-9 6ZMA/6ZM system. [. . . ]
