2.6-B. CMOS Reset (JP6)
If you have been locked out of your system because you forgot your password or set the CMOS incor-
rectly, or have just finished flashing your BIOS follow the instructions below.
By following this procedure, you will erase your password and reset the CMOS.
2.6-C. USB Connector (USB2)
This connector is for the additional USB connector* (which adds 2 more ports on a second USB channel).
2.6-D. Cooling Fans (FAN1, FAN2, FAN3, FAN4, FAN5, FAN6)
In addition to installing your CPU, Tyan highly recommends that you install a CPU fan/heatsink combina-
tion, and if needed, additional chassis fans. To this end Tyan has provided several connectors to power
the fan(s), as well as the fan pinout (shown above). Here is some information you may find useful:
