1b = Boot flags valid. The bit should be set to indicate that valid flag data is
present. This bit may be automatically cleared based on the boot flag valid
bit clearing parameter, above.
[6:0] - Reserved
BIOS support for the following flags is optional. If a given flag is supported, it
must cause the specified function to occur in order for the implementation to
conform with this specification.
The following parameters represent temporary overrides of the BIOS default
settings. BIOS should only use these parameters for the single boot where these
flags were set. If the bit is 0b, BIOS should use its default configuration for the
given option.

00b = System default
01b = Request quiet display

[4] -
1b = Force progress event traps. When set to 1b, the BMC transmits PET
traps for BIOS progress events to the LAN or serial/modem destination for
the session that set the flag. Since this capability uses PET traps, this bit is
ignored if for connection modes that do not support PET such as Basic Mode
and Terminal Mode.
[3] -
1b = User password bypass. When set to 1b, the management station BIOS
boots the system and bypasses any user or boot password that might be set
in the system.
[2] -
1b = Lock Sleep Button. When set to 1b, directs BIOS to disable the sleep
button operation for the system, normally until the next boot cycle.
[1:0] - 00b = Console redirection occurs per BIOS configuration setting
01b = Suppress (skip) console redirection if enabled
10b = Request console redirection be enabled
