ok... let me see if i understand this...

1. you ported a program from linux to dos.
2. it runs in dosbox.
3. it runs in freedos.
4. it runs in dosbox in freedos.

 ig> Anyone have an ideas what might cause this behaviour?

what memory model (http://www.digitalmars.com/ctg/ctgMemoryModel.html) did you

are you trying to use EMS or XMS memory?

have you tried running your program in ""real"" dos? like MSDOS 6.22 or
whatever the last version of PCDOS was...
