I asked a question about my AST Rampage 286 on the net recently and got
back a couple of replies asking for switch settings.
On my board there are two switches S1 has ten bits and S2 has 8.
S1-1 to S1-4 is the amount of conventional/extended memory the board is
to provide. Note that these switches are ignored depending on the setting
on S2 . . .
1-1, 1-2, 1-3, 1-4
ON, ON, ON, ON is 128K
ON, ON, ON, OFF is 256K
up to
OFF, OFF, OFF, OFF which is 2048K
S1-5 to S1-8 indicates the boards Base I/O Address
1-5 1-6 1-7 1-8
208 ON, ON, ON, ON
218 ON, ON, ON, OFF (Factory setting - 1st board)
etc
S1-9 enables/disables Dual Page Mode. The Factory setting is enabled (ON)
S1-10 is Unused.
S2-1 to S2-7 is the amount of conventional/extended memory ALREADY installed
on you system. (Number of 128K blocks like S1-1 to S1-4 above).
S2-8 Enable Parity Checking if ON.
