Memory Controllers
The Orion memory components (OMC) include the OMC-DP (data path) and the OMC-DC (data
control). The OMC-DP provides a consolidated memory data path between the P6 bus and the memory
interface chips (MICs). The MICs provide the interface between the P6 bus (via the OMC-DP) and the
installed memory modules. Each MIC handles 1/4 of the memory data path, and is optimized for
interleaved performance using read-around writes and data buffering. The OMC-DC is an addressing
and control device for the DRAM array that interfaces to the OMC-DP.
BIOS Components
Flash EPROM
The system board (MSMT329) uses a flash EPROM chip (MYPG782) for the system’s Basic
Input/Output System (BIOS). The System Setup Guide contains information about reprogramming the
flash EPROM with a new BIOS when necessary. It also defines the features of the AMIBIOS Setup
program, used to modify the BIOS parameters.
BIOS Jumper
The BIOS jumper (J16) allows the BIOS password to be bypassed. By default, the jumper is OFF,
which enables the password. When the jumper is ON, the password is disabled.
NOTE You must remove the PCI option boards and the processor module (or P6 bus termination card) to
access the BIOS jumper.
