Thread: Dumping Interrupt Vector Table

I am trying to dump the contents of Interrupt Vector Table on 32 bit Widows 7 machine using the following code excerpt.

Code:

#include <stdio.h>
#define WORD unsigned short
#define IDT_001_ADDR 0         // start address of the first IVT vector
#define IDT_255_ADDR 1020     // start address of the last IVT vector
#define IDT_VECTOR_SZ 4    // size of the each IVT vector

int main(int argc, char **argv) {
        WORD csAddr;            // code segment of given interrupt
        WORD ipAddr;            // starting IP for given interrupt
        short address;            // address in memory (0-1020)
        WORD vector ;            // IVT entry ID (0..255)

        vector = 0x0;
        printf("n-- -Dumping IVT from bottom up ---n");
        printf("Vector\tAddress\n");

        for(address=IDT_001_ADDR; address<=IDT_255_ADDR; address=address+IDT_VECTOR_SZ,vector++) {
            printf("%03d\t%08d\t", vector , address);
            // IVT starts at bottom of memory, so CS is always 0x0
            __asm {
                    PUSH ES
                    mov AX, 0
                    mov ES,AX
                    mov BX, address
                    mov AX, ES:[BX]
                    mov ipAddr ,AX
                    inc BX
                    inc BX
                    mov AX, ES:[BX]
                    mov csAddr, AX
                    pop ES
            };
            printf("[CS:IP] = [%04X,%04X]n" ,csAddr, ipAddr);
    }
}

It does not compile with Visual Studio as Visual Studio has probably withdrawn support for 16 Bit compilation. I built it in Pelles C, however the executable would crash when I try to run it. The problem, as I figured from some research over the internet, has to do with the 16 bit register reference (to ES). I do not however clearly understand the issue. I would really appreciate if someone could help me out with getting this to work on win32
