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

Removing the Ethernet ROM

To access the Ethernet ROM you must remove the scanline

coprocessor module.

Note

Depending on the system conﬁguration, the Model 30 or

38 system can have two types of coprocessor modules: the

graphics coprocessor module or 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 has only four post locks with tabs holding it

to the system board.
