checklist

If you have any problems with your computer immediately after installing the Inboard 386/PC, check the following items in order.

• Is the power cord plugged into the wall outlet? Are the cables and cords attached correctly?

•

Are the boards inside the computer properly seated and reconnected?

• Do any boards memory? (When you turn on the power, the computer will beep -short-short-short] -- if you haven't disabled conventional memory on the computer's system board or on another add-in board.)

• Is the Inboard 386/PC cable plugged into the 8088 socket and not the 8087 socket?

• Is the Inboard 386/PC cable oriented correctly in the 8088 socket on the system board and the socket on the the the connectors pushed all the way into the sockets?

• If an 8087 was installed on the system board, did you remove it?

• Did you set switch 2 correctly (OFF if an 80387 is installed and ON if it isn't)?

If your computer doesn't work correctly after you've checked these potential problems, turn to Appendix B for troubleshooting advice.

Conventional memory is limited to 640K bytes. The two ways to get around the 640K-byte limitation are expanded memory and extended memory.

Beyond conventional memory

Both expanded and extended memory provide memory beyond 640K bytes. The following sections explain the differences between expanded memory and extended memory.

Expanded memory

Expanded memory is usable memory beyond DOS's 640K-byte conventional memory limit. Expanded memory lets you use large

programs by accessing memory beyond 640K -- memory that

DOS can't reach. DOS application programs which conform to
