Hi All,

I have a Bochs configuration file that works enough to run the 4.5.0
grub floppy image.  I just ran it as "bochs -f b -q".

Anyone have an idea what CPU model is being simulated by default
and which other variants can be tested using different Bochs options?

How about simulating a hard disk?  Anyone done that with RTEMS?

Erwin.. did you get the TCP/IP stack working?

I would really like to get to the point where this is an easy
way to test nearly all of RTEMS.

Erwin.. then maybe someone can do the same for PearPC. :)

Here is the configuration file:
