®
82801DB I/O Controller Hub 4 (ICH 4) Erratum 7
PROBLEM: For a complete description of the ICH 4 erratum 7, see the Intel
82801DB I/O Controller Hub 4
(ICH 4) Specification Update, order number 290745 found at
http://developer.intel.com/design/chipsets/specupdt

IMPLICATION: For a complete description of the ICH 4 erratum 7, see the Intel 82801DB I/O Controller Hub 4
(ICH 4) Specification Update, order number 290745 found at

.
WORKAROUND: None.
STATUS: This erratum was fixed in the B0 chipset stepping.
2. Wake From an ACPI Sleep State Using Wake Methodologies May
Fail
PROBLEM: The desktop board hardware leaves the LAN RESET (LAN_RST#) signal unasserted before and
after the resume well power (VccSus3_3 and VccSus1_5) is valid, instead of asserting it for 10 ms after valid
power, which is required by the Intel 82801DB I/O Controller Hub 4 (ICH4) Datasheet (order number 290744).
The result is that LAN wake attempts may fail.
NOTE: Wake from LAN* using the MagicPacket* utility will not be affected by this errata.
IMPLICATION: Users that take advantage of LAN wake methods to wake systems from an ACPI sleep state
may experience some wake failures.
WORKAROUND: None.
STATUS: This erratum may be fixed in a future BIOS revision.
