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,
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 because 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 DRAM SIMM size is 1 in.
Install the PCI-MXI-2
This section contains general installation instructions for the PCI-MXI-2.
Consult your computer user manual or technical reference manual for
specific instructions and warnings.
1.
Plug in your PCI-based computer before installing the PCI-MXI-2.
The power cord grounds the computer and protects it from electrical
damage while you are installing the module.
