Removing Memory Modules
Before You Continue
If you are not upgrading the Ethernet ROM, go to
Chapter 5 to complete this upgrade.
Continue with the next section, Removing the Ethernet
ROM, only if you want to maintain the same Ethernet
address in the VAXstation 4000 system.
Removing the Ethernet ROM
To access the Ethernet ROM you must remove the graphics
coprocessor module.
Note
Depending on the system configuration, the Model 76
system can have two types of coprocessor modules: the
graphics coprocessor module and the scanline coprocessor
module. These two modules are similar except for a
couple features. To remove the scanline coprocessor, you
must remove three screws from the mounting brackets,
then release the tabs from the post locks. The graphics
coprocessor module has only four post locks with tabs
holding it to the system board.

To remove the scanline coprocessor module from the system
board, do the following and refer to Figure 4–5 and Figure 4–6:
1. Unscrew and remove the three screws on the mounting
brackets that attach the coprocessor to the system board.
The mounting brackets remain attached to the system
board.
