computer to automatically set the best refresh rates for
your monitor.
Set Refresh Rates (resolution). This option allows you to
select a refresh rate for each resolution supported by
your monitor.
The resolution is the size of the image on the screen
expressed in picture elements or pels (for example,
800 x 600).
Before you select refresh rates, read the documentation
that came with your monitor. The documentation should
include the horizontal frequency and refresh rates that
work best with your monitor. You can also experiment
with different settings to find which settings produce the
best image.
Do not select a setting that exceeds the
capabilities of your monitor. If you do, your
Warning! monitor will not function properly. If this
happens, turn off your system unit and restart
the Setup Utility.

Disk Drives

The Disk Drives Setup screen shows you the size of the
drives installed in your computer and what additional
drives can be installed. The following paragraphs
describe each of these options:
Diskette Drive (A: or B:). This option shows you an
entry for each diskette drive on your computer. If you
add or change a diskette drive, you must select the
correct diskette drive type on the Devices and I/O Ports
screen.
Hard Disk Drive and CD-ROM Drive: These options
show you entries for each hard disk drive and the CD-
ROM drive that are already installed, or that can be
installed in your computer. You can have a maximum of
four IDE drives installed on your system.
The Disk Drives Setup screen lists four IDE drive
selections:
•
Hard Disk Drive 1 is attached to Local Bus connector
1 on the system board and set as the Master device.
This is the hard disk that comes preinstalled with
your computer.
•
Hard Disk Drive 2 (if installed) is attached to Local
Bus connector 1 on the system board and set as the
Slave device.
•
CD-ROM Drive 3 (if installed) is attached to Local Bus
connector 2 on the system board and set as the
Master device. If your computer does not have a
CD-ROM drive, this selection will read Hard Disk
Drive 3.
•
Hard Disk Drive 4 (if installed) is attached to Local
Bus connector 2 on the system board and set as the
Slave device.
When you choose one of the four IDE drive selections
from the Disk Drives Setup screen, the screen for that
drive appears. That screen shows the size of the hard
disk installed and allows you to choose the IDE
Performance mode for each drive. It may also allow you
to make changes to the following:
Local Bus IDE Mode. This option allows you to set the
speed (performance) at which the drive will transfer
data. To get the best disk performance, run IDE drives
(such as a hard disk or CD-ROM drive) in High
Performance mode.
