M-AUDIO MM401 - Manual (Page 11)

Trouble-Shooting
If you are having problems using your MM-401 it is probably a
good idea to reread this manual and make sure you have prop-
erly installed the card. If you can’t find the source of your diffi-

SYMPTOM : The computer won’t boot with the card in.
Everything is fine without the card. (This may include strange
error messages.)
SOLUTION
: Run the INSTALL program and make sure the
interrupt/IRQ you have set the card to is free. Also, make sure
the card is recognized at the address selected and that all of the
diagnostics pass.
SYMPTOM: The diagnostic program finds the address that the
card is at, but says “No Interrupt Detected.”
SOLUTION:
You are probably running Windows in your system.

Windows is running, even in the background, it steals the inter-
rupt/IRQ from the MM-401 (even if you run 401TEST.EXE from
the DOS Prompt). Try running the program from DOS — it
should now work.
SYMPTOM: My computer can’t find the card when I run my

SYMPTOM : The card works fine with my DOS programs but
