Howdy,

I just overhauled the hardware information in the INSTALL notes for 1.5.
Could a bunch of you check this over to make sure it's right?  I based it
on posts to port-sparc and my shaky interpretation of the kernel source.

In particular, I'm not sure about any of the sun4 stuff.

Thanks,

   NetBSD/sparc System Requirements and Supported Devices

     Supported machines

           o   sun4c (e.g. the SS1, SS1+, SS2, IPC, ELC, IPX, SLC, and some
               clones such as the Opus 5000)

           o   sun4 (e.g. the 4/100, 4/200, 4/300, and 4/400)

           o   sun4m (e.g. the 4/600, Classic, LX, SS4, SS5, SS10, SS20, Voy-
               ager, JavaStation 1, and some clones such as the Tadpole Sparc-
               Book 3)

     Unsupported machines

           o   sun4d (e.g. SPARCcenter 1000 and SPARCcenter 2000)

           o   sun4u and other UltraSPARC based machines.

               There is a separate sparc64 port for these machines.  Refer to
                     http://www.netbsd.org/Ports/sparc64/index.html

           o   Solbourne machines

           o   Other JavaStation models

     The minimal configuration requires 4 MB of RAM and ~60 MB of disk space.
     To install the entire system requires much more disk space, and to run X
     or compile the system, more RAM is recommended, as NetBSD with 4 MB of
     RAM feels like Solaris with 4 MB of RAM - slow.  Note that until you have
     around 16 MB of RAM, getting more RAM is more important than getting a
     faster CPU.

     Supported devices
