Doom Legacy / Problems with DOS & and winedbg

Trying to debug a problem into INT21_CreateDirectory,
I want to run doom3.exe into winedbg. (DL tries to create the directory
in %HOME%, set to /home/something... LOL)

Unfortunately, winedbg complains on the first int21 call :
First chance exception: interrupt 21 in vm86 mode in vm86 code

How can this be avoided ?
