Checking System Memory
Your computer comes with 4MB of RAM on a SIMM. DOS and
application programs that run under DOS use the first 640KB of
memory. You can use the memory above 1MB as extended
memory.
When you boot your system, the system BIOS detects the type
of RAM and updates the total memory size automatically. You
see the memory configuration displayed in the
Base Memory
and
Extended Memory
fields on this SETUP screen.
You may need to change these values if you install optional
memory (for instance, a memory option card) that the BIOS
doesn’t automatically recognize when you start your system.
Change the values in these fields to reflect your additional
memory. When you restart your system, all memory, including
the additional memory, will be available.
Setting the Video Display Type
The
Video Card
option lets you define the type of adapter
you are using for your primary display. If you connected your
monitor to the computer’s built-in VGA port, select
EGA/VGA.
If you installed an optional video card, follow the guidelines
below to select the correct adapter type.
