Version 1.x (Debut in 1989): Original
Forth-based boot firmware.
|
|
|
Version 2.x (Debut in 1991): The
original, predecessor of the IEEE 1275 standard.
|
SPARCstation 2 through UltraSPARC IIIi and IV platforms
|
Version 3.x (Debut in 1995): Sun's
fully compliant IEEE 1275 standard (Open Firmware).
|
Version 4.x (Debut in 2001): Still
IEEE 1275 compliant, but rearchitected for more modularity to
cover a broader range of systems.
|
|
Version 5.x (Debut in 1995): Used
a different OpenBoot application that was implemented in C, rather
than Forth. It included a VxWorks-based Real Time OS and a System
Controller Application. The LPOST firmware component was shared
(due to use of a common processor Uniboard) with the Sun SPARC Enterprise
15K and 25K System Management Services (SMS) Service Processor
software used on its System Controller. This version shipped
exclusively with the Sun Fire 2x00, 4x00, and 6x00 servers.

Sun System Firmware (SysFW)
|
Version 6.x
(Debut in 2005):
Derived from the
previously separate OBP (Host-side) and ALOM (Service
Processor-side), SysFW 6.x includes both 4.x OpenBoot and the
Service Processor-side ALOM-CMT. ALOM-CMT was derived from the
Advanced Lights Out Manager (ALOM 1.x) firmware versions used on
Sun Fire V1x0, V2x0, and V4x0 entry-level servers. This version of
firmware is exclusive to UltraSPARC T1 processor based servers.

Version 7.x (Debut in
2007): Derived from SysFW 6.x, and sharing the
same OBP, POST, Hypervisor, and vBSC components, SysFW 7.x
utilizes ILOM (commonly used on x86-based and x64-based Sun systems) instead
of ALOM-CMT. This version of firmware is currently exclusive to
the UltraSPARC T2 and UltraSPARC T2 Plus processor based servers.

System Management Services (SMS)
|
Version 1.x (Debut in 2001): A
set of Solaris packages that included both firmware-level (OBP &
POST, Service Processor, and so on) components as well as Solaris-level
application support.
|
Sun Fire E12K through E25K servers
|
Extended System Facility Control Program (XCP)
|
Version 1xxx (Debut in 2007): A
set of Solaris packages that included both firmware-level (OBP &
POST, Service Processor, IO Box, and so on) components as well as
Solaris-level (Solaris OS, Sun Management Center, Sun Validation Test Suite) components. This version
ships exclusively with the Sun SPARC Enterprise M3000, M4000, M5000,
M8000, M9000 servers.
