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.
