Manual Conventions; Cpu Prototypes - TYAN TAHOE-A ATX Manual

Refer to Addendum A (AMI BIOS CMOS Setup) and Addendum B
(Award BIOS CMOS Setup) for the setup requirements and the CMOS
Configuration information, including instructions to change the password,
to format a hard disk, and to troubleshoot CMOS errors. Both AMI and
Award BIOS Setup documents are also available in the Adobe Acrobat
format. Please refer to the Web Page located at ftp://ftp.tyan.com/

1.5. Manual Conventions

In this manual, the following terms are used in reference to setting up
jumpers:
1. When the term "Close" or "On" is used, the pin (pins) specified for the
jumper should be connected (closed), and the circuit of the connecting pins will
be shorted.
2. When the term "Open", "Shorted", or "Off" is used, the pin (pins)
specified for the jumper should not be connected, and the circuit of the connect-
ing pins will not be shorted.
1.6. CPU types
Currently, Intel produces two types of Pentium II processors: the "Boxed"
(or Active) Processor, and the Passive Processor.(Refer to the Pictures
shown on Page 8) These two types of processors are essentially the same
in design. The only difference between these two types of processors lies
in their cooling methods. The Boxed (Active) Processor is equipped with
a CPU cooling fan and heatsink built in with the CPU, and the Passive
Processor is equipped with a heat sink only. These two types of CPUs
provide the user with the same function, and should be installed in the
"Pentium II" slots on the S1684SA board. (Refer to Chapter 3 for the
installation and removal of Pentium II processors.)
