Nvram, nvci & SC flashproms
The system controller has a 100-MHz MicroSPARC IIep, 32
Mbytes of
DRAM (128 MB on the SC V2), a serial interface and a 10/100Mbit
ethernet interface.
The SC has its own power-on self test, called
SCPOST
, and its own
operating system, the
RTOS
(sometimes referred to as vxworks), which is
held in a 2 MB flashPROM on-board. (This is the
sgrtos.flash
file in
the flashupdate patch).
The SC also has
SPOST
and its own application called the
ScApp
which
is held in an 8 MB flashPROM on-board. (This is the
sgsgsc.flash
file
in the flashupdate patch).
The SC maintains a centralized TOD, hostids and MAC addresses and its
own host setups in an NVRAM chip.
It also maintains information for four domains in an NVCI chip
