Try a small C program that sets ioperm and then execs Wine... (iopl
might work as well...) (You might also want to drop root priviledges
before execing Wine....)
Gert
Something like:
#include<sys/io.h>
int main(int argc, char *argv[])
{
ioperm(0,0x3ff,1); /* Dangerous, overkill, allows access to all ports */
/* setuid(<your uid>); /* Drops permissions - have never used it,
check docs... Environment should probably be set up as well */
execlp("wine","wine","application.exe"); /* My unix C coding
needs practice, so this might just destroy your PC, read docs... */
return 1;
}
