SIMM lnstallation
Your computer comes with 8MB of memory on two 4MB
SIMMs. You can increase the memory up to 128MB using
1MB, 2MB, 4MB, 8MB, 16MB, and 32MB SIMMs (when
readily available).

The table below lists the monitors that are directly supported
by the Mach32 accelerator.

Video Memory, Modes, and Monitors

Check the monitor documentation to see if its characteristics
match one of the listed types. If so, select that type in the
Mach32 installation program.

This system comes with 1MB of VRAM soldered on the main
system board. You can increase the video memory to 2MB by
installing eight VRAM ZIP chips (256KB x 4, 60ns, fast-page
mode). You must fill all eight sockets.

For EPSON monitors, see the second table for information on
the monitor type to select.

The table below lists the video modes supported by the
system.

If the monitor does not match any of these types, set up a
custom monitor.

Hard Disk Drive Types
This system comes with a hard disk auto-sensing feature.
Some drives do not support the auto-sensing feature. If the
system does not correctly define your hard disk drive, you
can define up to two drive types in SETUP.
(1) bpp=bits per pbel: 4 bpp=l6 colofs, 6 bpp=256 colors,
16 bpp=65,000 colors, 24 bpp~l6.7 mlson colors
