The Micro ATX IR2 mainboard is a high-performance personal computer
mainboard based on the AMD Athlon
®
processor. This mainboard provides
onboard Creative
®
ES1373 PCI technology in audio. The AMD Athlon
®
processor is the newest microprocessor in the AMD K86
TM
family of
microprocessors.
The mainboard uses the highly integrated AMD
®
751 system controller and
AMD 756 peripheral controller. The AMD-751 system controller features:
the S2k system interface supports a 100Mhz clock and double-data rate
(DDR) transfers, the 33MHz 32-bit bus interface supports up to three
masters, the 66MHz AGP 1.0 compliant interface supports 2x data transfer
mode, and High Speed memory designed to support a 100MHz SDRAM (PC-
100-compatible-DIMM) with serial presence detect(PSD). The AMD-756
peripheral bus controllers feature an integrated ISA bus controller, an
enhanced IDE controller with Ultra DMA-66 support, and a keyboard/mouse
controller.
The MS-6191 ATX IR2 mainboard is one of our system board to implement
the AMD-750 chipset (AMD-751 and AMD-756), which supports a single
Slot A for AMD Athlon
®
processor.
