CONFIGURATION - MEMORY

Install Memory Modules in any combination and in any order in the TOP TWO SLOTS

on the Memory Expansion Board

2MB is standard and 16MB is maximum.

Memory configuration is accomplished with the SETUP routine on the DIAGNOSTICs diskette.  The jumper settings for the memory expansion boards are as follows:

32-Bit System Memory Board (000413)
E1 to E3, E5 to E6*	640 KB base memory
E7 to E8	Disables extended memory
E1 to E2, E4 to E5	256 KB base memory
E2 to E3, E4 to E5	512 KB base memory
E8 to E9	Enables extended memory
* Default

CAUTION:  DO NOT connect E3 to E4 or E6 to E7.  System  board damage may occur.

 0.5 to 2 MB 16-Bit memory Board (000458)

1 to 2, 4 to 5*	4 MB
1 to 2, 5 to 6	6 MB
2 to 3, 4 to 5	10 MB
2 to 3, 5 to 6	12 MB
* Default

1- to 2-MB 9000450) & 4- to 8-MB (000459)

32-Bit Memory Expansion Boards

J101 Setting	1- to 2-MB Board	4- to 8-MB Board
2 to 3*	Disables second	Disables second
	1-MB of memory	4-MB of memory
1 to 2	Enable second	Enables second
	1-MB of memory	4-MB of memory

The 384 Kbyte of expanded memory cannot be set as extended as per Service Advisory 353 which is paraphrased as follows:

The...384 Kbytes are used as Lotus/Intel/Microsoft (LIM) 4.0 compatible expanded memory.  This expanded memory can be accessed using the CEMMP utility contained on the User Programs diskette.  This expanded memory cannot be used as Extended memory.


GENERAL -- MATH COPROCESSOR

Intel 80287-8 MHz or 80C287-12 MHz math coprocessor are supported on this unit.

Make sure that switch SW1-5 on the system board is on the appropriate setting to designate which math coprocessor is installed.

ON -- 8-MHz 80287 coprocessor or          coprocessor not installed

OFF -- 12-MHz 80C287 coprocessor


CONFIGURATION - FAN SPEED

To set the fan speed on N machines: Set the E1 jumper

 - the default setting is for Auto, E1 would be jumpered on pins 2 and 3.

 - the Full speed, E1 would be jumpered on pins 1 and 2. This setting would cause the fan to

   run all of the  time.
