There has been some talk on the net of how annoying the 4dos beeps are when
it loads.  Here is a patch that will get rid of them.  This patch still leaves
the non-registration information in the program and that sould stay there.
If the registered version also beeps, this patch will fix it too.

1. Search 4DOS286.EXE for E6 61. (with something like PC-Tools)
2. replace E6 61 with 90 90.
3. find next occourance of E6 61 and replace it with 90 90 also.
4. repeat steps 1-3 for 4DOS88.EXE.

REMEMBER:

Do not distribute modified copies of the program.

Note:

Since this is the machine code command to turn on the speaker, you
could effectivly search any program that makes noise and replace
these bytes to silence it.
