Parameter # Parameter Data (non-volatile unless otherwise noted)
Boot initiator
mailbox
(semi-volatile)
[1][2
]
7 This parameter is used as a mailbox for holding information that directs the
operation of the OS loader or service partition software.
Note: Since this information is retained by the BMC and may be readable by
other software entities, care should be taken to avoid using it to carry secret data.
Data1: Set Selector = Block selector
Selects which 16-byte info block to access. 0-based.
Data 2: (17) Block data
The first three bytes of block #0 are required to be an IANA Enterprise ID Number
(least significant byte first) for the company or organization that has specified the
loader.
Up to 16-bytes per block of information regarding boot initiator, based on protocol
and medium.
The BMC supports five blocks of storage for this command. Previous values are
overwritten. The BMC does not automatically clear any remaining data bytes if
fewer than 16 bytes are written to a given block.

1. The designation ‘semi-volatile’ means that the parameter will be kept across system power cycles, resets, system
power on/off, and sleep state changes, but is not preserved if the management controller loses standby power or is
cold reset. Parameters designated as semi-volatile are initialized to 0s upon controller power up or hard reset,
unless otherwise specified.
5. IPMI allows software to use the boot initiator mailbox as a way for a remote application to pass OEM parameters
for additional selection of the boot process and direction of the startup of post-boot software. If additional
parameters are not included, the system boots the primary/first-scanned device of the type specified.

[5] - Line Editing
0b = Disable
1b = Enable (Factory default)
[4] - Reserved
[3:2] - Delete control (only applies when line editing is enabled)
00b = BMC outputs a <DEL> character when <BKSP> or < DEL > is received
01b = BMC outputs a < BKSP >< SP >< BKSP > sequence when < BKSP > or < DEL > is
received (Factory default)
[1] - Echo control0b = No echo 1b = Echo (BMC echoes characters it receives) (Factory default)
[0] - Handshaking - BMC outputs a [SYS]<newline> after receiving each terminal mode IPMI
message and is ready to accept the next message
0b = Disable
