4 Determine the size of each of your memory boards (including any already
installed). The size is determined as follows:
—
four 256 KB SIMMs in bank O only = 1 MB.
— eight 256 KB SIMMs in banks O and 1 only = 2 MB.
— sixteen 256 KB SIMMs in banks O, 1, 2, and 3 = 4 M B .
— four 1 MB SIMMs in bank O only = 4 MB.
— eight 1 MB SIMMs in banks O and 1 only = 8 MB.
— sixteen 1 MB SIMMs in banks O, 1, 2, and 3 = 16 MB.
5 Determine the calculated values X and Y for each of your memory
boards (including any already installed). If you are using more than one
board, their order is important: 16 MB boards come first followed by
8 MB, 4 MB, 2 MB, and 1 MB boards. The calculated values X and Y
are determined as follows:
a
b
c.
d
The boards must be in order from largest to smallest. In the boxes of
the column labeled Size on the form below write the amount of
memory on each board.
Do the subtraction indicated for board 1 and write the result in the
=X column.
Copy the Size figure for board 1 into the two places indicated for
board 2.
Do the calculations indicated for board 2 if you have it. Continue
this process for boards 3 and 4 if you have them, otherwise leave
those lines blank.
