The following figure summarizes the previously explained basic information flow related to the
system boot options parameter #100.
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.

Table 8-11. System Boot Options Parameter #100 - Data 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. When reading from the storage area
and you find any of these two values, your software should assume that no user-specific
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 byte checksum over the boot parameters data section. (LSB first)
For backward compatibility reasons, the checksums 0x0000 and 0xFFFF are accepted
as valid. They indicate that no checksum has been calculated and stored.
