            | Issue | Can I preform any real mode BIOS calls in QNX Neutrino or QNX4? |  
            | Solution | Unfortunatly not.  BIOS calls are unavailable in Neutrino and QNX 4, because they run in 32-bit protected mode. 
 However in QNX Neutrino there is a function called _intr_v86
 
 http://qdn.qnx.com/support/docs/neutrino_qrp/lib_ref/i/_intr_v86.html
 
 that executes a real-mode software interrupt.  Look at the help docs for _intr_v86 for further information.
