Hi,

 

The attached patch fixes a problem preventing Windows XP / 7 from booting with bug check error A5 (0x00000011, 0x00000006) on the Gigabyte GA-M57SLI- S4 board. Microsoft documentation states that this bug check occurs because, “SCI_EN never becomes set in PM1 Control Register”. This patch sets the SCI_EN bit. The patch applies to any board featuring the MCP55 south bridge.
