MAXDATA PLATINUM 90004R Server System
# Parameter Data (non-volatile unless otherwise noted)
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 first doing a 'commit write' causes any 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
1 Data 1
[7:0] - Service partition selector. This value is used to select which service
partition BIOS should boot using. This document does not specify
which value corresponds to a particular service partition.
00h = Unspecified
2 Data 1
[7:2] - Reserved
[1] - 1b = Request BIOS to scan for specified service partition. 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.
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 pushbutton reset / soft-reset
(e.g. "Ctrl-Alt-Del")
[0] - 1b = Do not clear valid bit on power up via power pushbutton or
wake event
