# 10_LPC_4x40s_Sandy_SL.txt

# This patch is required only for running Snow Leopard on 4x40s
# with Sandy Bridge CPU.
#
# Note: SL does not support 4x40s Ivy...
#
# It injects the device ID for 6-series LPC.  The 4x40s is
# has a 7-series chipset, which is not natively supported 
# by SL's AppleLPC driver.  This forces the driver to load
# as it will think the device is 6-series LPC.

#   LPC fix injects device 0x1C49 HM65
