Flash Layout

BIOS can be supported from either firmware hub (LPC) or on SPI, for PrAMC-7311 it is
designed to support from SPI flash and as usually the ME and GbE technology supported
firmware also reside on flash devices only so that total firmware's can be combined into
single image and going to be placed into the SPI flash. PrAMC-7311 support of two flash
devices with 8MB each and with the help of MMC the particular flash can be selected for
boot the BIOS, by default system boot from flash device 0 because default selection line
enabled on SPI is of #CS0. Below the figure is the flash composition to support the BIOS,
