Rafal K. Boni has added a lot of new support to NetBSD/sgimips
    that has been committed to NetBSD-current.  Most notably is new
    support for the IP22 (Indigo2, Indy, Challenge S).  A list of all
    the major new additions is as follows:
    
    
      - Support for the IP22 (Indigo2, Indy, Challenge S)
      
 - Support for the HPC I/O peripheral ASIC.  There is where SCSI,
        Ethernet, etc. live on the Indigo2 and Indy
      
 - Support for the Seeq 8003 Ethernet attached to the HPC ASIC,
        found on the Indigo2 and Indy
      
 - Support for the Dallas 1286 clock found on the Indigo2 and
        Indy
      
 - IOC1/2 memory map
      
 - Support for the Indigo2/Indy IMC (this is that to which all other
        devices are attached)
      
 - Support for the SCC serial ports on Indigo2 and Indy
      
 - Support for configuring an SCC console
      
 - Generic software interrupt implementation, derived from
        NetBSD/mipsco
      
 - Basic EISA support for the Indigo2
      
 - Dynamic system configuration support, derived from
        NetBSD/pmax
    
 
    
    An example kernel configuration file for Rafal's Indigo2 can be found
    in sys/arch/sgimips/conf/TEAL.
