Manual for KD7E/333 series
BIOS-ProtectEasy Jumper (JAV)
The BIOS of the motherboard is contained inside the Flash ROM. If the jumper JAV is
set as closed, you will be unable to flash the BIOS to the motherboard. However in this
status, the system BIOS is protected from being attacked by serious virus such as CIH
virus.
Under special conditions, the jumper JAV should be set as OPEN. For further details,
refer to the BootEasy part of appendix.
Setting the jumper JAV as open(default), meanwhile disabling the Flash Write Protect
item from Advanced BIOS Features in AWARD BIOS CMOS Setup, allows you to
flash the BIOS to the Flash ROM.
The DMI (Desktop Management Interface) system information such as the CPU type/
speed, memory size, and expansion cards will be detected by the onboard BIOS and
stored in the flash ROM. Whenever the system hardware configuration is changed, DMI
information will be updated automatically. However, setting jumper JAV as closed makes
flashing BIOS and updating DMI information impossible. Therefore, set JAV as open
when changing the system hardware configuration, or the error message Unknown
Flash Type will be displayed on the screen, and DMI information update will be fail.
Clear CMOS (JCC)
If you want to clear CMOS, unplug the AC power supply first, close JCC ( pin1 & pin2 )
once, set JCC back to the normal status with pin2 & pin3 connected, then power on the
system.
