Note
If you are going to install NetWare 286, version 2.2, you
cannot assign a user-defined drive type for your drive
without installing NetWare IDE drivers. You can obtain
these drivers (IDE.DSK and IDE.OBJ) by downloading
IDE286.ZIP from Netwire in CompuServe®. Alternatively,
you can select one of the pre-defined hard disk drive types
that most closely matches the drive you are installing.

Checking System Memory
Your computer comes with 2MB or 4MB of random access
memory (RAM) on SIMMs. 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 base memory size and the extended
memory size automatically. You see the memory configuration
displayed on this SETUP screen.
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.

Additional options
Two additional chipset feature options allow you to slow down
your system in case you need compatibility with slower option
cards or diskette drives.
If you enable the ISA 1 wait state option, the system
inserts one wait state in a 16-bit ISA cycle rather than providing
the fastest processing at zero wait states.
The
Slow
Refresh option,
when enabled, improves system
performance because it shortens the time needed for each
refresh cycle.
