Now that I have my hard drive set up, I keep getting protection 
violations.  It mostly happens when using gcc.  It is along the
lines of:

protection violation: 0000

The hex dump at the bottom is often different.  Like ls began with "c3 ".

But this also happens when I boot up sometimes.  Or use ls.  But
then other commands like em work.  I have no 80387.
Could this just be a problem with the bios not setting up the 
%cr0 flag correctly?  Basically, I haven't even been able to compile
the hello world program yet!  Any ideas?
Is it time to get an 80387 (or is a 80287 sufficient).
