N-O - MCP INSTALLATION & SYSTEM CONFIGURATION NOTES: DOCUMENT 3032
NCR
3150 Intel487 SX
MCP socket is located underneath the keyboard. i487 SX is
automatically enabled.
PC6 8087-2
Reports indicate that this computer can't use an Intel Above Board
and the 8087 at same time. Contact NCR for more information.
NEC
V20 based computers 8087
Intel cannot guarantee compatibility with non-Intel
microprocessors. Contact the your computer's manufacturer for more
math coprocessor compatibility information.
Portable 386 Intel387 DX
Set jumper near 387 to pins 2-3
Powermate II Intel387 DX
The beveled corner on the 387DX socket of this computer is 180
degrees out of place. However, a tiny arrow on the system board
correctly points toward pin 1 of the 387DX. Align the beveled
corner of the 387DX with this tiny arrow to correctly install the
chip and avoid damage to the computer or chip.
NEC Ultralite SL25C Intel387 SL
The customer may see the i387 SL-25 Mobile Math CoProcessor fail
the IEEE Conformance Test on our Utilities Diskette, if they don't
have a BIOS revision of 24 or later. If the customer's BIOS
revision is earlier than rev 24 have them contact NEC for an
update.
Powermate 386/25S Intel387 DX
Set Switch 1 to ON, and Jumper JP6 2-3. Pin 1 of MCP socket is
closest to base of the ZIF socket lever. System's Hardware Setup
utility must be run to configure the system.
Powermate 386 (16 MHz) Intel387 DX
Jumper pins 2-3. System may fail the Intel Diagnostics Environment
test. This does not effect operation of system.
Powermate 386 (25 MHz) Intel387 DX
Jumper 13G2 or 5L1, Pins 1-2 for Intel, Pins 2-3 of Weitek, also
DIP switch 1, position 7 should be ON for Intel, and OFF for
Weitek.
Prospeed 386 Intel387 DX *
There is a jumper to the left of the MCP socket (when facing the
front of the system). Set this jumper from position 2-3 to position
1-2.
Powermate 386 (20MHz) INtel387 DX *
*This machine uses a ZIF (Zero Insertion Force) socket for the
Intel387 DX. To find the orientation look for a small triangle
silk-screened at one of the socket corners or on the motherboard;
this is pin 1.
NORTHGATE
386-16 Intel387 DX Jumper "W5", pins 2-3
ORCHID
TINY TURBO 286
This accelerator board has problems when using a math coprocessor
and an Above Board. The problem can be solved by placing a dummy
chip in the 8087 socket on the system board. Contact Orchid for
more information. Intel doesn't have a dummy
chip for accelerator boards.
P-S - MCP INSTALLATION & SYSTEM CONFIGURATION NOTES
PACKARD BELL
PB286LP Intel287 XL
Reports indicate that the Packard Bell manual instructs you to set
a jumper for an external clock. This step is actually unnecessary.
486SX Intel487 SX
Some units of this model of system shipped with the wrong BIOS. If
they have the wrong BIOS, the system reports that a mcp is
present in the Intel486 SX. Customer should contact Packard Bell
for a new BIOS. Packard Bell's number is: 800-733-4422.
PANASONIC
1850 Intel287 XL
Install 10 MHz oscillator (Radio Shack part number AXX- 7149).
Insert into socket Y3 to enable the math coprocessor.
1925SX Intel387 SX
There is a jumper located next to the microprocessor on the
motherboard, that needs to be set to enable, after you have
installed the math coprocessor. The jumper is marked
ENABLE/DISABLE.
SAMSUNG
386SX-25 Notebook Intel387 SX
This system uses VLSI chipset. Samsung testing shows ULSI mcp would
not work in this system, while the Intel chip worked fine.
SANYO
MPC 386DX-16 Intel387 DX
The Math Coprocessor may be recognized as a 287, when the system
BIOS is v1.04 SE. Replacing this BIOS with v1.04 solves the
problem.
SHARP
MZ100 8086 System 8087
This system does not have an MCP socket. If the customer sends 8087
and system to Sharp, Sharp hardwires the chip onto the system
board.
