The MIC-3355 provides a VGA controller for a high resolution VGA
interface. The MIC-3355's CN2 is a DB-15 connector for VGA
monitor input. Pin assignments for the CRT display are detailed in
Appendix B. Share memory architecture supports 0.5 MB, 1 MB, 1.5
MB, 2 MB, 2.5 MB, 3 MB, 3.5 MB and 4 MB system memory. The
memory is configured in the system BIOS setup.
The parallel port is normally used to connect the CPU card to a printer.
The MIC-3355 includes an on-board parallel port, accessed through a
DB 25-pin connector, CN6 on the front panel.
The parallel port is designated as LPT1 and can be disabled or
changed to LPT2 or LPT3 in the system BIOS setup.
The MIC-3355 provides two connectors for connection of keyboard
and PS/2 mouse on the front panel. Since these two connectors are
identical, please be careful to plug in keyboard or mouse into the
correct connector.
The MIC-3355 offers two serial ports: COM1 in RS-232, COM2 in
RS-232/422/485. These ports let you connect to serial devices (a
mouse, printers, etc.) or a communication network.
You can select the address for each port ( For example, 3F8H
[COM1], 2F8H [COM2]) or disable it, using the BIOS Advanced
Setup program, covered in Chapter 4.
