Title Real Mode BIOS calls
Ref. No. QNX.000010231
Category(ies) Development
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.
