IPMI Setup for Intel SCB2 Motherboard
Doug White <email@example.com>
These are recommended settings for the Intel SCB2 (and similar)
motherboard for optimal use under FreeBSD, with full console redirection
from BIOS and from loader(8), and enabling remote control over LAN (optional).
Only the "Setup Utilities" section should be required; the IPMI commands
can be used for automated reconfiguration if desired.
This configuration assumes that the machine will be connected to a (secure)
LAN and that the serial console will be connected to a console server or
similar device, and not a modem. This means that you do not plan on using
the built-in modem paging capabilities and/or PPP or Direct mode IPMI sessions
to the BMC (from a tool such as Intel Direct Platform Control).
Some of the items give the data bytes for equivalent IPMI commands. Use
System Setup Utility (SSU) Settings
- Change Serial Port2 to COM1 settings
- Address 3F8, IRQ 4
- This makes the onboard RJ45 ports COM1 and thus the default serial
- You can disable Serial Port1 if it isn't present on your system (i.e.,
- Put "-h" in /boot.config to make FreeBSD use the serial console by
default. See Handbook section 16.5 ("Setting Up the Serial Console") for
- Change BIOS console redirection settings (under Server / Console Redirection)
- Enable serial console redirection
- Serial port: COM1 3F8 IRQ 4
- Baud Rate
- 9600 if using default FreeBSD speeds
- Whatever you like if you have built new boot1/2/loader with
BOOT_COMCONSOLE_SPEED set (I've rebuilt it to use 115200)
- Flow Control
- Whatever your hardware supports
- Platform Event Manager
- Access Mode to "Disabled"
- Configure PEP
- Configure LAN (optional, if LAN IPMI access desired)
- set static IP or DHCP
- Disable LAN alerts
- Access Mode to "Always available"
- Must set SNMP trap string if enabled
Set Channel Access for Channel #1 (serial) -- 0x20
Set Serial Mux -- 0x2
- Same effect as changing the SSU settings above for EMP
- Platform Event Filtering off
- Disable access mode (always shunt to SYSTEM [BIOS & host])
- These can be configured in SSU. 'Shared' channel access mode can't,
but I don't think we want to use it on this system.
Set Serial Config --
- Updates Enabled
- set to SYSTEM
