The Clear Cmos Jumper, Clr-Cmos; Front Side Bus Speed, Fsb - Kontron 886LCD/ATX(GV) User Manual

KTD-00647-C

4.14 The Clear CMOS Jumper, Clr-CMOS.

The Clear CMOS Jumper is used to clear the CMOS content.
To clear all CMOS settings, including Password protection, move the Clear CMOS jumper (with or without
power on the system) for approximately 1 minute.
Alternatively if no jumper is available, turn off power and remove the battery for 1 minute, but be careful to
orientate the battery correctly when reinserted.

4.15 Front Side Bus Speed, FSB

Select CPU base clock to one of 3 options by configuring the FSB jumper row (JP5) as shown below.
The CPU used has itself output signals that indicate what the maximum/default frequency to be used is. Please
also note that the CPU internal clock multiplier is fixed by the manufacturer.
"CPU select": Will let the CPU / BIOS automatically control the base clock (default).
"100MHz setting": Will force CPU input clock to 100MHz and the internal CPU clock and FSB will be set
accordingly.
CPU clock = 100MHz x Clock multiplier
FSB clock = 400MHz
"133MHz setting": Will force CPU input clock to 133MHz and the internal CPU clock and FSB will be set
accordingly.
CPU clock = 133MHz x Clock multiplier
FSB clock = 533MHz
