TATUS
2. Wake From an ACPI Sleep State Using Wake Methodologies May
Fail
P :
The desktop board hardware leaves the LAN RESET (LAN_RST#) signal unasserted before and
ROBLEM
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.
I :
Users that take advantage of LAN wake methods to wake systems from an ACPI sleep state
MPLICATION
may experience some wake failures.
W :
None.
ORKAROUND
S :
This erratum may be fixed in a future BIOS revision.
