Both Windows and Linux tend to have slight problems with cut and paste not always working 
oh well. 
 
 
oh and the second one should have been: 
 
2. I released a proof-of-concept tarball of a bochs+plex86 configuration which demonstrated a 
simple "cycle-burn" user program, which clocked out at 90% of native (host) speed.   That's 
not intended to be a valid benchmark, but more to get an idea of the upper watermark of 
application performance when the OS is quiet, and thus does not require much emulation by 
the bochs component.   For more information search the bochs developers email list for 
"plex86".
