Owner`s manual

The console program automatically interleaves the memory modules to
give the largest possible set. The SET MEMORY command allows you
to override the default. This command modifies the configuration stored in
the EEPROM. The new configuration takes effect the next time the system
is reset or powered up.
An interleave set consists of memory modules in one-, two-, four-, or eight-
way configurations. Up to eight interleave sets can be configured. The
command can be used to set an upper bound on the memory used by the
console.
The default action interleaves memory so that the largest interleave factor
is obtained for each group of memory modules. If you have more modules
than you can interleave evenly, the console program repeats the criteria
with the remaining memory modules until only single arrays remain. An
interleave set will be built from like-sized memory modules or from memory
modules whose cumulative value is equal to the largest memory module in
the set. The console program configures the memory modules starting with
the lowest XMI node number, whichis placed at the lowest physical address.
Interleave set A always has a starting address of 0. Subsequent interleave
sets have starting addresses that are the sum of the memory sizes of
preceding interleave sets. As can be seen in the console display, an
interleave set number of "–" indicates that the memory module was not
included in the configuration.

Additional information about the qualifiers includes:
• /Console_limit:n allows you to reserve the highest addressed physical
memory for special hardware or applications, where n is that
hexadecimal address. The value is rounded up to the next even page
boundary. The console program begins building its in-memory data
structures, such as the CCA and bitmap, in memory locations below
hexadecimal address n.
• For the /Interleave qualifier, the interleave-list can have the format
of:
(node + node ..., node,...)
where node is the XMI node number of a memory module. Commas
separate each set of modules to be interleaved. Each set contains
memory modules, separated by plus signs. The console program
configures the modules in the order you specify, placing the first module
at the lowest physical address.
