Trinity 400 (S1854) Jumper Settings

Note for Pentium III 600+ MHz or Celeron 600+ MHz users.
 There is no need to worry about setting the correct jumper settings for a Pentium III or a Celeron at 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.
