- When DOS boots, is sets a bit in low memory that acts as a flag to
- indicate the presence of a math coprocessor (8087, 80287).
- If a DIP switch is set incorrectly or you are using a clone without
- the DIP switch, you can use "MATHCHIP.COM" to set this bit.
- Software that checks the coprocessor flag will now acknowledge the
- presence of the 8087 or 80287.
-
- Do not run MATHCHIP.COM if you don't have a coprocessor. The machine
- will "hang" waiting for a response from the non-existent coprocessor.
-
- MATHCHIP.COM is NOT resident. It sets one bit and exits, so no
- memory will be lost.
