Tsunami AT   (S1830)  Jumper Settings

Note for Pentium III 600+ MHz users.
There is no need to worry about setting the correct jumper settings for a Pentium III 600+ MHz because the CPU multiplier is hardwired into the CPU and changing jumper settings will not make any difference.  The BIOS will automatically detect the correct CPU speed that is installed.
