[comp.os.misc] To BIOS or not to BIOS?

  You might have seen this in a couple of other areas, but I'll post a
copy here for the general...

  I am in the midst of a small war debating whether or not one should
use system BIOS where it is available (on IBM style machines). One side
is arguing compatibility and the other side is pushing performance. At
one time, I was for BIOS on everything, but after experience and readings
of various articles, I currently stand on the side of direct hardware
interfacing. Many operating systems do not use BIOS, because one is not
available, and interfacing is done through device drivers (whether BIOS
is there or not). The article series in DDJ regarding the 386BSD port
appears to be going the direct hardware route. Is this indeed what most
other operating systems for the IBM PC world (and others that may apply)
are doing? Thanks for the input.
