Wow, my attempt was close to some of the other examples, but Andy Ruder
came up with the right results for me, thanks!

And it makes more sense now. Sheesh!

From Andy:

#include <sys\farptr.h>
#include <go32.h>

int main (void)
   {
    long int x;

    // Ok, the formula for accessing DOS memory using
the_go32_conventional_mem_selector()
    // command is segment * 16 + offset, so we need to access 0x40 * 0x10
+0x6c
    // This assumes the first argument in PTR in pascal is segment and
thelatter offset.

    x = _farpeekl(_go32_conventional_mem_selector(), 0x40 * 0x10 + 0x6C);

    printf("The BIOS tick count is %d.", x);
   }

Thanks All.
