Questions:
1. Is there any interest in hacking the code to support multithreading
using the pthread library (one bochs CPU on one thread) ? It would be
nice to be able to use both CPUs of my Blade_1000_ to run a
SMP-x86-machine...
2. Any interest in fixing your source to compile&run on Solaris/SPARC
using Sun's Workshop compiler (current Bochs is gcc-only code... ;-( ) ?
