The 80386 I-Cache board is a full-sized (13.8" x 12.025") motherboard
which took all of its memory as DRAM plugged into a proprietary 32-bit
memory card.  There are two versions of the I-Cache board, identified by
part numbers 09-00010, and 09-00021, which are silk-screened on the
component (top) side of the motherboard.

The most common memory card used with the I-Cache board is the M500.  This
is part number 09-00011.  The upper left corner has "385 Memory Board" 
silk-screened on many M500 cards.

This document is for the Mport 325 and Mport 333 Portable computers.  This system is 
based on the Intel 80386-25 and 80386-33 CPUs respectively.  It has a built-on video
system based on the Cirrus Logic video chipset.  It supports an external monitor, and 
has one 16-bit slot, which can accommodate a 2/3 length card.  The backplane connector
is exposed, to allow access like a desktop case for the card.

Up to 8MB is supported inside the unit, using 1Mx9 SIMMs.  There are two serial and one
parallel port.  The parallel port connector can be used for a parallel device, or can
be used to connect an external floppy drive.

The units come with either a 40MB Alps drive, or a 120MB Conner drive installed.  One 
3.5" 1.44MB floppy drive comes installed.

The video card comes with drivers for Windows 3.0, but not Windows 3.1.  The drivers
were written by Cirrus Logic.  There are also drivers for AutoCAD release 10, GEM 3.x,
Ventura 2.0, Lotus 1-2-3 version 2.xx, and Lotus Symphony.  The built-in display has
a 640x480 VGA Monochrome screen supporting 16 levels of gray.

Jumper J2 is used to configure the battery backup method.  To use the on-board battery, 
place a jumper block connecting pins 2-3.  If you wish to connect an external battery, 
pin 1 is the battery positive lead, and pin 4 is for battery negative.

You can clear the contents of the CMOS memory by placing a jumper block connecting 
pins 3-4, then turning on the power.  Turn off the power, configure the jumper for 
either the on-board or external battery, and turn the power back on.  The system
will act as if it has never been turned on before.

M710 memory card:
=================

This memory card may be used on this motherboard to allow up to 12MB to be added to 
the memory already installed on the motherboard.  There are sixteen (16) SIMM sockets
on the memory card (four banks of 4 sockets).  The first two banks of memory can
accept 256Kx9 SIMMs, or 1Mx9 SIMMs.  The second two banks of memory can only accept 
1Mx9 SIMMs.  The four banks of memory are numbered zero, one, two, and three.  Bank
zero on the M710 uses the same addresses as bank zero on the motherboard (the four
sockets on the motherboard).  Therefore, if the motherboard memory sockets are
populated, bank zero on the M710 must be left empty (or that memory will not be 
recognized).

There are four jumpers on the M710, which configures the type of memory installed in
each of the four banks of memory.  They are set as follows:

W1  Pin 1-2  Four 1Mx9 SIMMs in bank 0  (or when empty)
    Pin 2-3  Four 256Kx9 SIMMs in bank 0

W2  Pin 1-2  Four 1Mx9 SIMMs in bank 1  (or when empty)

In the table above, 256K indicates that four 256Kx9 SIMMs are installed in the bank,
1MB indicates that four 1Mx9 SIMMs are installed in the bank, and 4MB indicates that 
four 4Mx9 SIMMs are installed in the bank.  The above shows all of the possible memory
configurations.

Please note that Bank 0 and Bank 1 are on the motherboard.  Banks 2 and 3 are found on
the M810.  Each bank consists of four SIMMs, and all four sockets within a bank must
be filled.

When installing more than 16MB of memory, BIOS relocation must be disabled.  Bios 
relocation copies the video Bios (C0000-C7FFF) and the system ROM Bios (F0000-FFFFF) into
RAM.  The motherboard adds 15MB to these addresses (F00000) to be able to differentiate 
between the ROM and RAM.  Enabling the relocation feature causes the memory above 16MB 
to become non-contiguous and therefore inaccessible.

In the table above, 256K indicates that four 256Kx9 SIMMs are installed in the bank,
1MB indicates that four 1Mx9 SIMMs are installed in the bank, and 4MB indicates that 
four 4Mx9 SIMMs are installed in the bank.  The above shows all of the possible memory
configurations.

When installing more than 16MB of memory, BIOS relocation must be disabled.  Bios 
relocation copies the video Bios (C0000-C7FFF) and the system ROM Bios (F0000-FFFFF) into
RAM.  The motherboard adds 15MB to these addresses (F00000) to be able to differentiate 
between the ROM and RAM.  Enabling the relocation feature causes the memory above 16MB 
to become non-contiguous and therefore inaccessible.

In the table above, 256K indicates that four 256Kx9 SIMMs are installed in the bank,
1MB indicates that four 1Mx9 SIMMs are installed in the bank, and 4MB indicates that 
four 4Mx9 SIMMs are installed in the bank.  The above shows all of the possible memory
configurations.

Please note that Bank 0 and Bank 1 are on the motherboard.  Banks 2 and 3 are found on
the M810.  Each bank consists of four SIMMs, and all four sockets within a bank must
be filled.

When installing more than 16MB of memory, BIOS relocation must be disabled.  Bios 
relocation copies the video Bios (C0000-C7FFF) and the system ROM Bios (F0000-FFFFF) into
RAM.  The motherboard adds 15MB to these addresses (F00000) to be able to differentiate 
between the ROM and RAM.  Enabling the relocation feature causes the memory above 16MB 
to become non-contiguous and therefore inaccessible.

In the table above, 256K indicates that four 256Kx9 SIMMs are installed in the bank,
1MB indicates that four 1Mx9 SIMMs are installed in the bank, and 4MB indicates that 
four 4Mx9 SIMMs are installed in the bank.  The above shows all of the possible memory
configurations.

Please note that Bank 0 and Bank 1 are on the motherboard.  Banks 2 and 3 are found on
the M810.  Each bank consists of four SIMMs, and all four sockets within a bank must
be filled.

When installing more than 16MB of memory, BIOS relocation must be disabled.  Bios 
relocation copies the video Bios (C0000-C7FFF) and the system ROM Bios (F0000-FFFFF) into
RAM.  The motherboard adds 15MB to these addresses (F00000) to be able to differentiate 
between the ROM and RAM.  Enabling the relocation feature causes the memory above 16MB 
to become non-contiguous and therefore inaccessible.

+                       +
+=======================+

The External Cache Card allows the addition of 64K, 128K, or 256K of
external cache to the motherboard.  It also provides a Weitek 4167
socket for a co-processor installation.

64K external cache
==================

Install eight 8Kx8 SRAM chips into U1, U2, U5, U6, U9, U10, U14, and U15.
The chips must be 25ns or faster.  Make sure that W1, W2, W3, and W4 on 
the card are not jumpered.

128K external cache
===================

Install four 32Kx8 SRAM chips into U1, U2, U5, and U6.  The chips must be
25ns or faster.  Make sure that W1, W2, and W3 on the card have jumper 
blocks installed, and that W4 is not jumpered.

256K external cache
===================

Install eight 32Kx8 SRAM chips into U1, U2, U5, U6, U9, U10, U14, and U15.
The chips must be 25ns or faster.  Make sure that W1 on the card is not
jumpered, and that W2, W3, and W4 have jumper blocks installed.


After completing the cache installation on the card, insert the External
Cache Card into the special slot on the motherboard.  To activate the cache,
set the External Cache feature to Enabled in the CMOS setup screen.  Press
<Ctrl><Alt><Esc> after booting, then press <PgUp> to get to the second setup
screen.  After setting the parameter, press <Esc> to save the settings and 
reboot the system.  If you press <F10> instead of <Esc>, the system will not 
reboot, and the settings will not be saved.
This document is for the baby-sized (13.3" x 8.5") Gemini VL-Bus motherboard.  
The part number for this board is 09-00144-xx.

It's identifying features are: an LED between expansion slots #5 and #6; six 16-bit 
expansion slots; two 16-bit/VL-Bus expansion slots; four sockets for SIMMs; a socket 
for an OverDrive CPU; two IDE interface connectors; one floppy connector; two serial
port connectors; one parallel port connector.


The ISA bus speed for this motherboard is fixed at 8MHz.  The VL-Bus bus speed is
determined by the CPU speed.  If the CPU is a 486SX-25, or 486DX2-50, the VL-Bus 
bus speed is 25MHz.  If the CPU is a 486SX-33, 486DX-33, or 486DX2-66, the VL-Bus
bus speed is 33MHz.

In the table above, 256K indicates that four 256Kx9 SIMMs are installed in the bank,
1MB indicates that four 1Mx9 SIMMs are installed in the bank, and 4MB indicates that 
four 4Mx9 SIMMs are installed in the bank.  The above shows all of the possible memory
configurations.

When installing more than 16MB of memory, BIOS relocation must be disabled.  Bios 
relocation copies the video Bios (C0000-C7FFF) and the system ROM Bios (F0000-FFFFF) into
RAM.  The motherboard adds 15MB to these addresses (F00000) to be able to differentiate 
between the ROM and RAM.  Enabling the relocation feature causes the memory above 16MB 
to become non-contiguous and therefore inaccessible.

This document is for the baby-sized (13.3" x 8.5") JX30G VL-Bus motherboard.  
The part number for this board is 09-00189-xx.

It's identifying features are: an LED between expansion slots #5 and #6; seven 16-bit 
expansion slots; two 16-bit/VL-Bus expansion slots; four sockets for SIMMs; a ZIF socket 
for an OverDrive CPU; IDE interface connector; one floppy connector; two serial
port connectors; one parallel port connector.

The VESA Local Bus speed is determined by the CPU speed.  If the CPU is a 486SX-25, or 486DX2-50, the VL-Bus 
bus speed is 25MHz.  If the CPU is a 486SX-33, 486DX-33, or 486DX2-66, the VL-Bus
bus speed is 33MHz. A 50 MHZ CLK is not yet a current VESA standard specification 

The ISA bus speed for this motherboard is set at 8.33MHz.  The CPU clock speed is
determined by the Oscillator.  If the CPU is a 486SX-25, or 486DX2-50, the Bus 
clock speed is 1/3.  For the 486SX-33, 486DX-33, or 486DX2-66 CPUs, the Bus
clock speed is 1/4. 

The following shows all of the possible memory configurations.

In the table above, 256K indicates that (1) 256Kx36 SIMM is installed in the bank,
1MB indicates that (1) 1Mx36 SIMM is installed in the bank, and 4MB indicates that 
4Mx36 SIMM is installed in the bank.  The above shows all of the possible memory
configurations.

When installing more than 16MB of memory, BIOS relocation must be disabled.  Bios 
relocation copies the video Bios (C0000-C7FFF) and the system ROM Bios (F0000-FFFFF) into
RAM.  The motherboard adds 15MB to these addresses (F00000) to be able to differentiate 
between the ROM and RAM.  Enabling the relocation feature causes the memory above 16MB 
to become non-contiguous and therefore inaccessible.
