2.1 Determine Board Type and Configuration
Check the white sticker located on your board’s P2 connector. It contains information on board type, serial
number and release number.
Example:
[ USPIIi-1v/1-2MB-512-440 A1] [S1300786]
– Board Type: USPIIi-1v/1
– Extended (second level, or “L2”) Cache Size: 2 MBytes
– DRAM: 512 MBytes
– CPU Frequency: 440 MHz
– Revision: A1
– Serial Number: S1300786
See Chapter 3.1, "Overview," for a specification of possible board types.
The USPIIi-1v can be provided in two factory configurations, referenced in this manual as “ PS/2
configuration ” and “ Sun configuration ”. PS/2 configuration means that the board was pre-configured to use
PS/2-type keyboard and mouse; Sun configuration means that Sun type 5 keyboard and mouse can be
installed. USPIIi-1v and -1v/2p boards are only available in PS/2 mode. To determine the mode configured on
USPIIi-1v/2c and -1v/3 boards, check the position of jumper JP3304 on the baseboard (the slot #1 board).
– JP3304 not installed or set to 2-3 (inner position): board runs in Sun configuration
– JP3304 set to 1-2 (outer position): board runs in PS/2 configuration
Similarly, solder beads SB1801 to 1811 define the configuration in place. Refer to Appendix § B Jumper and
Solder Bead Configurations for a complete listing of jumper definitions.
Warning —
!
You must determine your board type and configuration in order to attach it properly to
peripheral devices. To change to a keyboard/mouse configuration different than the one set on your board,
please contact technical support.
