Other memory

m 4 MB of read-only memory (ROM)

m 8 kilobytes (KB) of nonvolatile parameter memory

m 512K to 1 MB of static RAM used as a level 2 cache integrated into the processor module

For more information and instructions on expanding your DRAM or video memory, see

Chapter 3, “Installing PCI Expansion Cards and Additional Memory,” in Setting Up Your Power

Macintosh manual.

Video modes

The table that follows shows the modes available for monitors that can be connected to the

monitor port, along with the number of colors or grays supported with 2 MB of video

memory (SGRAM) and with the optional expansion to 4 MB or 6 MB of SGRAM. The table

also lists the screen refresh rates in hertz (Hz) and kilohertz (kHz).

Peripheral component interconnect (PCI) expansion cards that can support other monitors

and special video requirements are available from other manufacturers. See your Apple-

authorized dealer for information.

Note: On some monitors from manufacturers other than Apple, the connector pinout

designates one pin for both green video and timing synchronization. These “sync on green”

monitors are not compatible with Power Macintosh computers. If you’re not sure what type

of monitor you have, check with your dealer.

You can use the Monitors & Sound control panel or the Control Strip to set a display mode

that is supported by both your monitor and the built-in video circuitry. Refer to the manual

that came with your monitor for a list of display modes that it supports.
