Bios settings are retained by the Motherboard Battery in the CMOS.
Disconnecting the battery clears CMOS and returns the settings to their
original state. Typically this can be done by simply removing the CMOS
battery and waiting about 15 seconds before reinserting and booting PC.
Nowadays most Motherboard manufacturers supply a jumper to not only
disconnect the battery but also ground the CMOS to effectively drain
any residual power.
The instructions for your MB are found below. JP5
is located to the left of the battery and next to the PCI 2 slot on
your MB. There is a Manual for your MB on this site and the MB layout
can be found at http://www.fixya.com/support/p281070-soyo_sy_k7vme_motherboard/manual-35533/page-5
Follow the steps below to clear the CMOS memory.
1. Clear the CMOS
memory by momentarily shorting pin 2-3 on jumper JP5. Its white cap can
easily identify this jumper.
2. Put the jumper back to 1-2 to allow
writing of new data into the CMOS memory.
