119MAXDATA PLATINUM 90002R Server System
Table 25. Boot Option Parameters
Parameter # Parameter Data (non-volatile unless otherwise noted)
Set In
Progress
(volatile)
0 Data 1 - This parameter is used to indicate when any of the following
parameters are being updated, and when the updates are completed. The bit
is primarily provided to alert software that some other software or utility is in
the process of making changes to the data. The change shall take effect when
the write occurs.
[7:2] - Reserved
[1:0] - 00b = Set complete. If a system reset or transition to powered down
state occurs while Set in Progress is active, the BMC goes to the
Set Complete state. If rollback is implemented, going directly to Set
Complete without doing a Commit Write causes pending write data to
be discarded.
01b = Set in progress. This flag indicates that some utility or
other software is presently doing writes to parameter data. It is a
notification flag only, it is not a resource lock. The BMC does not
provide any interlock mechanism that would prevent other software
from writing parameter data while.
10b = Reserved
11b = Reserved
Service
partition
selector
(semi-
volatile)
[1]
1 Data 1
[7:0] - Service partition selector. This value is used to select the service
partition BIOS should boot using. This document does not specify
which value corresponds to a particular service partition.
00h = Unspecified
Service
partition scan
(semi-
volatile)
[1]
2 Data 1
[7:2] - Reserved
[1] - 1b = Request BIOS to scan for specified service partition. The BIOS
clears this bit after the requested scan has been performed.
[0] - 1b = Service Partition discovered. The BIOS sets this bit to indicate it
has discovered the specified service partition. The BIOS must clear
this bit on all system resets and power ups, except when a scan is
requested.
BMC boot
flag valid bit
clearing
(semi-
volatile)
[1]
3 Data 1 - BMC boot flag valid bit clearing. Default = 0000b.
[7:5] - Reserved
[4] - 1b = Do not clear valid bit on reset/power cycle caused by PEF
[3] - 1b = Do not automatically clear boot flag valid bit if IPMI Chassis
Control command not received within 60-second timeout (countdown
restarts when a IPMI Chassis Control command is received)
[2] - 1b = Do not clear valid bit on reset/power cycle caused by watchdog
timeout
[1] - 1b = Do not clear valid bit on push-button reset / soft-reset
(e.g. <Ctrl><Alt><Del>)
[0] - 1b = Do not clear valid bit on power up via power push-button or
wake event
