SMI on Multiple-bit DRAM ECC Error (DMERR): When this bit is set, the generation of the hub
interface A SMI message is enabled when the MCH-M DRAM controller detects a multiple-bit error.
For systems not supporting ECC this bit must be disabled.
SMI on Single-bit ECC Error (DSERR): When this bit is set, the generation of the hub interface A
SMI message is enabled when the MCH-M DRAM controller detects a single bit error. For systems
that do not support ECC this bit must be disabled.
Reserved
SCI on Multiple-Bit DRAM ECC Error (DMERR): When this bit is set, the generation of the hub
interface A SCI message is enabled when the MCH-M DRAM controller detects a multiple-bit error.
For systems not supporting ECC this bit must be disabled.
SCI on Single-bit ECC Error (DSERR): When this bit is set, the generation of the hub interface A
SCI message is enabled when the MCH-M DRAM controller detects a single bit error. For systems
that do not support ECC this bit must be disabled.
