NOTES:
1.
Intel NM10 contains a single SATA device. The SATA Device ID is dependant upon which
SATA mode is selected by BIOS and capabilities exist in the SKU.
2.
Loaded from EEPROM. If EEPROM contains either 0000h or FFFFh in the device ID location,
then 27DCh is used. Refer to the ICH7 EEPROM Map and Programming Guide for LAN
Device IDs.§
