Entering WDEB386

Once WDEB386 is started, you can cause it to display its command prompt in the following ways:

1.Press CTL+ALT+SYSREQ

2.Generate a nonmaskable interrupt. (This can be disabled with the v2 command.)

3.Place an int 1 instruction in your code. This method should be used when debugging the real-mode portion of your virtual device. An INT 3 may also be used, but the debugger will not automatically pass over it.

4.Specify “b” as a command line parameter to WDEB386. This will pass control to the debugger just prior to VMM initialization, after all virtual devices have been loaded and the processor is running in protected mode.
