This setup will have no unallocated space in SPI chip and no intersections between flash regions. So, the right values for BIOS base and BIOS limit should be 0x0200 and 0x07FF respectively. BIOS region starts at offset 0x0000 and ends at 0x800000 (0x7FF 1)* 0x1000, which is obviously incorrect!īIOS regions should start at any offset between 0x200000 (end of ME region) and 0x250000 (begin of first firmware volume in image file) and end at the end of image file at offset 0x800000. ME region starts at offset 0x3000 and ends at 0x200000 (0x1FF 1)* 0x1000, which is correct.ģ. GbE region starts at offset 0x1000 and ends at 0x3000 (0x02 1) * 0x1000, which is correct.Ģ. So, this region map says to us (and to chipset logic too, if flashed to SPI chip as is) that:ġ.
