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. 1-6 Specification 2.

SOFTWARE DRIVER BIOS O. S. - 2M bits FLASH ROM. [. . . ] M We don't recommend you to setup your system speed to 75, 83 or 100MHz because these frequencies are not the standard specifications for CPU, Chipset and most of the peripherals. Whether your system can run under 75, 83 or 100MHz properly will depend on your hardware configurations: CPU, SDRAM, Cards, etc. 3. 6. CMOS RTC & ISA CFG CMOS SRAM There're RTC & CMOS SRAM on board; they have a power supply from external battery to keep the DATA inviolate & effective. The RTC is a REALTIME CLOCK device, which provides the DATE & TIME to system. [. . . ]
