Somebody asked for the code to get the DEVICE name 
of a CD-ROM. I accidentally deleted his mail, so I 
abuse this list:
#include <stdio.h>
#include <stdlib.h>
#include <go32.h>
#include <dpmi.h>
#include <dos.h>


/* This is untested, use at your onw risk */

#define WHATEVER_U_NEED 5  /* should be < 16k */

int main(int argc, char **argv){
    __dpmi_regs r;
    char foo[WHATEVER_U_NEED];
    /* You can typedef a struct for that
    ** instead of a char *, but watch out
    ** for alignment woes.
    */

    r.x.ax = 0x1501;
    /* Tell int 2f to use xfer buffer */
    r.x.es = (__tb >> 4 ) &0xffff;
    r.x.bx =  __tb & 0xf;

    __dpmi_int(0x2f,&r);
    dosmemget(__tb,WHATEVER_U_NEED, &foo);
    return 0 
}
