Using the built-in interfaces, you can connect most of your
peripheral devices directly to the computer, so you do not have
to install option cards. You can use the option slots to enhance
your system with extra functions such as a modem card, a
network controller card, or additional interface ports.
The shadow RAM feature speeds up processing by moving the
system and video BIOS into the RAM area of memory.
With the standard 512KB of video RAM, the VGA controller
supports standard resolutions up to 640 x 480 in 16 colors and
extended resolutions up to 640 x 480 in 256 colors or 1024 x 768
in 16 colors (interlaced or non-interlaced). When you upgrade
to 1MB of video RAM, the system supports extended
resolutions up to 1024 x 768 in 256 colors.
Your system may have been configured for you. If so,
everything you need to get started is already in place. Your
hardware configuration options have been set to ensure
optimal system performance. The hard disk drive already
contains the MS-DOS
®
operating system and Microsoft@
Windows.

In addition, the drivers needed to take advantage
of your system’s enhanced video resolutions have been
installed for you. Just connect your keyboard, mouse, and
monitor and you’re ready to go.
VGA Drivers
Your computer comes with VGA drivers for use with the
integrated VGA interface. With these drivers, you can take
advantage of the extended VGA features such as high
resolutions and 132-column text mode when you run popular
application programs. If your system was configured for you,
these drivers are already installed. If you need to install them
yourself, a README file on your Utility diskette describes how
to install the VGA drivers for common application programs.
