32    Some of these guest operating systems are easier to install and run than
33    others. The best supported mode is the DECstation 5000/200 emulation mode,

45    
46    Summary of changes between release 0.3.3.2 and 0.3.4:
47    
48            x)  When emulating a network of multiple machines, the emulated
49                machines can now be placed on different hosts.
50    
51            x)  NetBSD/evbmips can now be installed and run from a disk image.
52                (There is no INSTALL kernel for NetBSD/evbmips, so you need to
53                install using another OS, for example emulated NetBSD/pmax.)
54    
55            x)  NetBSD/sgimips can now be installed. Not onto a SCSI disk,
56                but the files can be exported via nfs from another emulated
57                machine. The sgimips machine can then netboot. (Read the
58                documentation for details.)
59    
60  The two most visible changes from version 0.3 to 0.3.1 are:  There have also been various other minor updates and bugfixes.
   
         x)  Name change (from mips64emul to GXemul).  
   
         x)  NetBSD/hpcmips can now be installed and run from a harddisk  
             image on an emulated NEC MobilePro 770, 780, 800, or 880.  
   
 There have also been many other updates and bugfixes, as usual.  
   
 This release has a number of known bugs, listed in the BUGS file, but feel  
 free to drop me an email regarding other bugs.
