4.1.18 BIOS Interface towards OS
4.1.18.1 Proprietary BIOS Data Area (BDA) Bytes
BIOS provides control for warm or cold reset types through the BIOS Data Area (BDA). The
following BDA bytes are required by the OS.
4.1.18.2 BIOS CLI Tool - IPMIBPAR
The IPMIBPAR tool can be used to change the IPMI Boot Parameter list when Linux is up and
running. It supports the following options:
LENGTH 12 8 The length of the floating pointer structure table in
bytes. The version 1.00 structure is 14 bytes long; so
this field contains 0Eh.

bytes specified by the length field, including
CHECKSUM and reserved bytes, must add up to
zero.
