QNX If there is one operating system that has a special place in my heart, it's QNX. This microkernel operating system served as my main desktop operating system for months and months back in the day, during the short-lived QNX Desktop scene - which died out due to a lack of interest from QNX' parent company, QNX Software Systems. The money is in the embedded and high reliability markets, and that's where QSS - understandably - focused its efforts. QNX was sort-of open sourced in September 2007, and today the company has announced the release of QNX 6.4, the first major release since 6.3 in 2004.

problem is, the BIOS does not spend as much time on pure cpu based computations as on device (PCI cards, storage devices) scan, and initialization loops (that are executed serially)
moreover, delays and timeouts are introduced in routines that detect devices that may not be available or may need some time to become so - think of a HDD taking some fractions of a second to spin up
