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.

CPU Bus Frequency Selection Jumper (JK1/J6)

Jumper	Pins	Description
JK1/J6	Closed Open	Automatically detect 66MHz and 100MHz CPU Bus Frequency. Virtually set 66MHz CPU Bus Frequency into 100MHz.

AGP Bus Frequency Selection Jumper (JK2/J7)

Jumper	Pins	Description
JK2/J7	Closed Open	66MHz AGP Bus Frequency AGP Bus Frequency same as CPU Bus Frequency

Upgrades

Cache : Non-Upgradeable.
CPU : Supports the following processors:
- 66MHz Front-side Bus:
  - Celeron 300A/128K cache
  - Celeron 333A/128K cache
  - Celeron 366/128K cache
- 100MHz Front-side Bus:
  - Pentium II 350/512K cache
  - Pentium II 400/512K cache
  - 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.
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.
