CHAPTER 2: JUMPERS & CONNECTORS
When working with the
586M , it is extremely
important that you avoid
static electricity. Always
ground yourself by wearing
a wrist or ankle strap.
Figures 1 on the next page shows the component layout of the 586MI system board with locations of the system board
jumpers and connectors. Note that most jumpers and connectors on the system board are labeled with proper names with
pin 1 marked as '1'. To avoid damaging the board and to have proper operation caution should be taken when connecting
these components.
SYSTEM BOARD JUMPERS
Jumpers are used to select between various operating modes. jumper switch consists of two, three, or four gold pins
projecting from the system board. Placing the plastic jumper cap over two pins connects those pins and makes a
particular selection. Using the cap to cover two pins in this way is referred to as shorting those pins. If the cap is not
placed on any pins at all, this is referred to as leaving the pins open.
Note: When you open a jumper, leave the plastic jumper cap attached to one of the pins so you don't lose it.

Care should be taken when installing the CPU into the Pin Grid rray (PG ) socket on the system board. Make certain
that pin 1 of the CPU chip is correctly aligned with pin 1 of CPU socket. The location of pin 1 on the CPU is denoted by a
small notch.
VESA Local Bus Jumpers
These jumpers allow any VL-Bus adapter to identify the speed of the system board.

Clear CMOS Data Jumper
The CMOS jumper JP15 is used to clear the system configuration data currently stored in the CMOS R M. ll system
setup information (hard disk type, date/time, etc...), stored in the CMOS, will be destroyed. This function would be useful if
you were to forget the user password for the system.
