System Memory Configuration
This SIS620 motherboard supports 168 pin DIMM of, 16Mb,
64Mb, 128Mb and 256Mb to form a memory size between 8MB to
1.5GB(SDRAM).
SIS620 chipsets provide “Table- Free” function, but do
remember that the DRAM must be 3.3V Unbuffered and 4 clock
type. User can use any DIMMs slot without any limit but if
use onboard VGA the DIMM must plug into DIMM1.

Standard CMOS Setup
Standard CMOS Setup allows you to record some basic
system hardware configuration and set the system clock and
error handling. You only need to modify the configuration
values of this option when you change your system
hardware configuration or the configuration stored in the
CMOS memory gets lost or damaged.
Run the Standard CMOS Setup as follows:

channels. The choice: Primary, Secondary,
Both.
Page 48

IDE Primary Master/Slave PIO
The four IDE PIO (Programmed Input /
Output) fields let you set a PIO mode (0-4)
for each of the four IDE devices that the
onboard IDE interface supports
Modes 0 through 4 provide successively
increased performance. In Auto mode, the
system automatically determines the best
mode for each device. The choice: Auto,
Mode 0, Mode 1, Mode 2, Mode 3, and
Mode 4.
Primary Master/Slave UltraDMA
UDMA (Ultra DMA) is a DMA data
transfer protocol that utilizes ATA
commands and the ATA bus to allow
DMA commands to transfer data at a
maximum burst rate of 33 MB/s. When
you select Auto in the four IDE UDMA
fields (for each of up to four IDE devices
that the internal PCI IDE interface
supports), the system automatically
determines the optimal data transfer rate
for each IDE device. The choice: Auto,
Disabled.
IDE Burst Mode
Selecting Enabled reduces latency
between each drive read/write cycle, but
may cause instability in IDE subsystems
that cannot support such fast performance.
If you are getting disk drive errors, try
setting this value to Disabled. This field
does not appear when the Internal
PCI/IDE field, above, is Disabled. The
choice: Enabled, Disabled.

Supervisor/User Password
These two options allow you to set your system passwords.
Normally, the supervisor has a higher ability to change the
CMOS setup option than the user. The way to set up the
passwords for both Supervisor and User are as follows:
1. Choose “Change Password” in the Main Menu and press
<Enter>. The following message appears:
“Enter Password:”
2. The first time you run this option, enter your password
up to 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 the same password “exactly” as you just typed again to
confirm the password and press <Enter>.
5. Move the cursor to Save & Exit Setup to save the
password.
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
the next time you turn your machine on.
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 JP1.
All setup information will be lost and you need to run the
BIOS setup program again.

hard disk detected by the BIOS, you can enter “Y” 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.

Save & Exit Setup allows you to save all modifications you
have specified into the CMOS memory. Highlight this
option on the Main Menu and the following message
appears:
