Jumpers
CMOS Clear Jumper (JBAT1)
| Jumper | Pins | Description |
|---|---|---|
| JBAT1 | 1-2 2-3 | Normal/Save CMOS settings Clear CMOS settings |
Caution : When clearing the CMOS settings, the power cord must be unplugged (since the standby power for the PIIX4E chipset comes from the power supply) and let the system rest for five seconds for the power to clear before returning the jumper to the Normal position.
Onboard VGA Jumper (JVGA1)
| Jumper | Pins | Description |
|---|---|---|
| JVGA1 | 1-2 2-3 | Enable onboard VGA Disable onboard VGA |
Power-On Mode Jumper (JP1)
| Jumper | Pins | Description |
|---|---|---|
| JP1 | 1-2 None | Boot up when power button is pressed. Immediate boot up when power cable is connected. |

- Pentium II 450/512K cache
- Pentium III 450/512K cache
- Pentium III 500/512K cache
- Single Edge Contact (SEC) cartridge. Uses the SLOT1 CPU socket. Not keyboard switchable. Disable cache to slow down the system.
- 66MHz Front-side Bus:
- RAM : Maximum on Motherboard: 256MB. Uses 8/16/32/64/128/256 MB DIMMs, 60ns or faster EDO SDRAM DIMMs. Supports only non-parity DIMM modules.
- The 168-pin DIMM sockets will support PC66/PC100 unbuffered 3.3V 1MBx64 (8MB), 2MBx64 (16MB), 4MBx64 (32MB), and 8MBx64 (64MB) and 16MBx64 (128MB) SDRAM DIMMs.
- Bank 1 will be populated as the default from the factory.
- No configuration jumpers: BIOS detects memory size, and memory type.
- This motherboard will not accept 36-bit DIMM modules (parity).
- Video RAM: Non-Upgradeable.
