How to Fix an Invalid EEPROM Configuration

Use MAX under Windows to edit the VXIpc 770/870B Series
configuration. Some of these settings are stored in files that the NI-VXI
software reads, while other settings are stored directly in the
VXIpc 770/870B Series EEPROM.
Certain EEPROM configurations, including invalid configurations, can
lock up your computer while it is booting. Generally, only the size and
location of the memory windows can cause your VXIpc 770/870B Series
to lock up your system. For example, many PCI-based computers will not
boot if a board in its system requests more memory space than the computer
can allocate. If you encounter this situation, you should reduce the size of
the VXIpc 770/870B Series user window. The EEPROM can become
corrupted if the VXIpc 770/870B Series is shut down while it is updating
the EEPROM.
If one of these situations occurs after you change the configuration,
complete the following steps to reconfigure the VXIpc 770/870B Series:
1. Power off your computer.
2. Change jumper W1 to the position shown in Figure 3-7b to restore the
factory configuration.
3. Power on the computer. The computer should boot this time because
the factory-default configuration is being used to initialize the
VXIpc 770/870B Series.
