Configuration EEPROM
The PCI-MXI-2 has an onboard EEPROM, which stores default register
values that are loaded at power-on. The EEPROM is divided into two
halves—a factory-configuration half, and a user-configuration half—so
you can modify the user-configurable half, while the factory-configured
half stores a back-up of the default user settings. The factory
configuration is a minimal configuration that allows you to boot your
PCI-MXI-2 regardless of the changes made to the user configuration.
For information on configuring the onboard EEPROM, refer to
Appendix C, EEPROM Configuration.
Onboard DRAM
The PCI-MXI-2 can accommodate one DRAM SIMM. Table 2-1 lists
the SIMMS you can use. You can use 32-bit or 36-bit SIMMS since
DRAM parity is not required. The PCI-MXI-2 can hold up to 16 MB of
onboard memory. The PCI-MXI-2 supports DRAM speeds of 80 ns or
faster. The maximum size for the DRAM SIMMs is 1 in.
