It's best to change the source so it uses `__dpmi_int' library function
instead of `int86x', because the latter only supports a subset of x86
interrupts.  It's all explained in the library docs (and the FAQ,
available as faq102.zip from the same place you get DJGPP v1.12, has the
rest).  The VESA API which the code tries to use isn't supported by
`int86x'. 

`segread' has no meaning in the DJGPP context, because DJGPP gives you a 
linear address space where the segment registers are (almost) always 
loaded with constant values.
