EFI/POSSE Commands

2. Specifying a cpu number without a state will display configuration status.

Examples:

*To deconfigure CPU 0 fs0:\> cpuconfig 0 off

CPU will be deconfigured on the next boot

*To display configuration status of cpus fs0:\> cpuconfig

<CPU configuration data displayed>

baud

Sets the baud rate and communication settings for a UART.

Syntax

baud <index> <baudrate>

Parameters

<index> 0 through the total number of UARTS minus one

<baudrate>

baud rate.

Operation

This command is used to change the speed for a UART in the server. This command works for all UARTs visible to EFI/POSSE. If the UART is part of processor dependent hardware (PDH) space and is initialized by the core firmware, this command communicates the settings to core firmware so the UART can be initialized with the new settings on the next boot. Server default is 9600 baud.

Other Communication parameters are listed in Table C-2.
