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.
boottest
Interacts with the speedy boot variable allowing it to be set appropriately.
Syntax
boottest Displays status of all speedy boot bits
boottest on Run all tests (for a normal boot time)
boottest off Skip all tests (for a faster boot time)
boottest [test] Displays status of specific Speedy Boot bit
boottest [test] [on|off] Sets or clears a specific Speedy Boot bit
