These two -chipsets are mostly compatible except for raminit. - -The datasheets for GS45 describe a high- and low-performance mode -for different CPU's. Coreboot currently disables GS45 altogether, -but forcing coreboot to treat high-performance GS45 as GM45 makes -the X200S boot with certain RAM configurations. - -1x2GB fails: http://paste.debian.net/hidden/ae66cff7/ -2x2GB fails: http://paste.debian.net/hidden/8802e220/ -2x4GB boots: http://paste.debian.net/hidden/61114378/ - -Hardcode-enable GS45 high-performance mode in coreboot, passing it -off as GM45.
