Chapter 2
Hardware Setup
This chapter includes sections of setting up jumpers on the
motherboard, the system memory configuration, the cache
memory configuration, and attaching the connectors. Refer
back to this chapter when you need to upgrade or
reconfigure your system and remember to turn off the
power of the system as well as all peripheral devices before
performing any work on the system.
Symbols used in this chapter are described below:
For 2-pin jumper:
Ð Close the jumper by inserting the jumper
cap over the two pins of the jumper.
Ð Open the jumper by removing the
jumper cap.
For 3-pin jumper:
Ð Close pins 1 and 2 with an jumper cap.

DRAM Timing Choose 60ns or 70ns (default). Do
not change this setting unless you
know the DRAM access time spec.

Use the default setting. This sets the
point of time that the CPU is
allowed to read and write to DRAM
and then perform.
Use the default setting. This setup
option allows you to determine the
delay time in completing the
transition from RAS to CAS.
Use the default setting. Burst
read/write requests are generated
by the CPU in four separate parts.
The 1st part provides the location
within the DRAM where the read or
write is to take place while the
remaining three parts provide the
actual data. The lower the timing
number is, the faster the system
memory will be addressed.
Use the default setting. This item
allows you to determine the timing
of the transition from ROW Address

MODEM Use IRQ Assign the IRQ number to the
modem which is being used so that
the ring signal can wakeup the

the VGA monitor, and the Suspend
Mode turns off the CPU and saves
the energy of the system.
HDD power Down Time is adjustable from 1 to 15
minutes. When the set time has
elapsed, the BIOS sends a command
to the HDD to power down, which
turns off the motor.

“Enter Password:”
2. The first time you run this option, enter your password
up to only 8 characters and press <Enter>. The screen
does not display the entered characters.
3. After you enter the password, the following message
appears prompting you to confirm the password:
“Confirm Password:”
4. Enter exact the same password you just typed again to
confirm the password and press <Enter>.
5. Move the cursor to Save & Exit Setup to save the

6. If you need to delete the password you entered before,
choose the Supervisor Password and press <Enter>. It
will delete the password that you had before.
7. Move the cursor to Save & Exit Setup to save the option
you did, otherwise the old password will still be there
when you turn on your machine next time.
8. Press <ESC> to exit to the Main Menu.
Note: If you forget or lose the password, the only way to access
the system is to clear the CMOS RAM by setting JP24
All setup information will be lost and you need to run the
BIOS setup program again.

The screen will ask you to select a specific hard disk for
Primary Master after you select this option. If you accept a
hard disk detected by the BIOS, you can enter ÒYÓ to
confirm and then press <Enter> to check next hard disk.
This function allows you to check four hard disks and you
may press the <ESC> after the <Enter> to skip this function
and go back to the Main Menu.
