The boot options need to be stored as a sequence of zero terminated strings. The following
table describes in detail the format of the boot options to be used when setting or reading the
System Boot Options parameter #100.
When writing or reading from the storage area, you can only read or write chunks of 16 bytes
at a time. For this reason, the IPMC memory is divided into numbered blocks of 16 bytes which
need to be addressed individually. For this purpose the "block selector" field in the request data
field is used.
7.11 Asynchronous Event Notification
To enable payload applications to be informed about graceful shutdown/reboot requests, the
"FRU Activate (Deactivate)" and "FRU Control (Graceful Reboot)" command message is routed
as a LUN2 message to payload interface.
Provided the payload application has registered to these commands via OpenIPMI library, it
gets informed and can take all necessary actions before the payload is gracefully
rebooted/shut-down.
Graceful Reboot and Graceful Shutdown is also communicated to the Intel CPU via internal
communication channel.
Table 7-7 IPMC Boot Parameter Storage Format
Byte
Description
0-1
Number of bytes used for boot parameters (LSB first)
The number of bytes must be calculated and written into these two bytes by the software
which writes into the storage area. The values 0x0000 and 0xFFFF indicate that no data has
been written to the storage area. If you are reading from the storage area and you find any of
these two values, your software should assume that no boot firmware boot options have
previously been written to the storage area.
2-n
Boot Parameters data
The boot parameters are stored as ASCII text with the following general format:
<name>=<value>, where all name/value pairs are separated by a zero byte. The end of the
boot parameter data is indicated by two zero bytes. Allowed and supported name/value pairs
are blade specific.
N+1 - n+2
16 bit checksum over the boot parameters data section (LSB first)
