This switch is factory set Off for a Monochrome display.
Set On to use a color display (CGA). The switch has no
effect with EGA or VGA.
Step 2 Install SIMMs
The AMI 486 EZ-Flex Base Board memory system consists
of two 32-bit DRAM memory banks. Both banks use Single
Inline Memory Module (SIMM) DRAMs and are labeled
BANK1 and BANK2 on the Base Board.
Use 256 KB x 9, 1 MB x 9, 4 MB x 9, or 16 MB x 9
SIMMs. All SIMMs must support column address strobe
(CAS) before row address strobe (RAS) refresh and should
have fast page mode accessing capability. The minimum
number of SIMMs is four (one bank of memory). SIMMs in
a given bank must be the same size. The SIMM slots on the
EZ-Flex Base Board are labeled BANK1 and BANK2.
