4.2.6.2 LAN Drivers and Setup
The IPMI-over-LAN feature must be used with the appropriate Intel NIC Driver, and the NIC
correctly configured in order for DPC LAN operation to occur transparently to the operating
system and network applications. If an incorrect driver or NIC configuration is used, it is possible
to get driver timeouts when the IPMI-over-LAN feature is enabled.
4.2.6.3 BIOS Boot Flags
A remote console application can use the IPMI Set System Boot Options command to configure
a set of BIOS boot flags and boot initiator parameters that are held by the management
controller. These parameters include information that identifies the party that initiated the boot,
plus flags and other information that can be used to direct the way booting proceeds after a
system reset or power-up. For example, the system can be configured to boot normally, boot
using PXE, boot to a diagnostic partition, etc.
4.2.6.4 Boot Flags and LAN Console Redirection
The system BIOS includes a LAN Console Redirection capability. This capability can only be
directed to one IP Address at a time. Thus, the boot flags and boot initiator information are also
used to tell the BIOS where to send LAN Console Redirection.
4.2.7 Wake On LAN / Power On LAN and Magic Packet Support
The baseboard supports Wake On LAN / Power On LAN capability using the onboard network
interface chips or an add-in network interface card. An add-in network card can deliver the wake
signal to the baseboard via the PME signal on the PCI bus. The actual support for Magic Packet
and/or packet filtering for Wake On LAN / Power On LAN is provided by the NIC. The
baseboard handles the corresponding wake signal.
