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) Pin 2-3 Four 256Kx9 SIMMs in bank 1 W3 Pin 1-2 Four 1Mx9 SIMMs in bank 2 (or when empty) W4 Pin 2-3 Four 1Mx9 SIMMs in bank 3 (or when empty) This document is for the baby-sized (13.3" x 8.5") Baby Gemini 486-50 motherboard. The part number for this board is 09-00125-xx. It's identifying features are: an LED between expansion slots #5 and #6; eight 16-bit expansion slots; eight sockets for SIMMs (two banks of 4); a socket for a Weitek 4167 coprocessor; one proprietary 32-bit slot which accommodates the M810 (a memory expansion card with eight sockets for SIMMs).

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.
