memory. The video controller supports pixel resolutions of up to
1600 x 1200 and up to 16.7 M colors. You cannot add video memory to this
system.
The SVGA controller supports analog VGA monitors (single and multiple
frequency, interlaced and noninterlaced) with a maximum vertical retrace
noninterlaced frequency of 100 Hz. Depending on the environment, the
controller displays up to 16.7 M colors in some video resolutions.
Compatible video drivers are provided with the operating system or the
utilities.
Parallel Port Connector (L)
The 25/15-pin connector stacks the parallel port beside the VGA video port.
BIOS programming of the super I/O chip registers enables the parallel port
and determines the port address and interrupt. The system BIOS provides
fields in the setup utility to easily enable the parallel port and set the port
address and interrupt. When disabled, the interrupt is available to expansion
cards.
Serial Port Connectors (M)
Both serial ports are relocatable. By default, port 1 is the left connector,
port 2 on the right. Each serial port can be set to one of four different
COMx ports, and each can be enabled separately. The system BIOS
provides fields in the setup utility to easily enable both serial ports and set
the port addresses and interrupts. When disabled, serial port interrupts are
available to expansion cards.
Keyboard and Mouse Connectors (N)
The PS/2-compatible keyboard and mouse connectors are mounted in a
single-stacked housing with the mouse connector to the left of the
keyboard. External to the system, they appear as two connectors.
You can plug in the keyboard and mouse to either connector before
powering up the system. BIOS detects the device connected at each
connector and configures the keyboard controller accordingly.
