 <h3>Experiments with other kernels and guest OSes:</h3>  
   
 <p>  
 Free Operating system kernels and other test programs can be  
 downloaded from various places on the Internet. Other kinds of software  
 (non-Free), if obsolete enough (such as Ultrix or Windows NT), can  
 sometimes be found in garbage containers, or perhaps be found for a cheap  
 price on ebay or at a flea market.  
   
 <p>  
 <font color="#ff0000">  
 NOTE: This is <i>not</i> a list of kernels that work in the emulator.  
 It is a list of kernels that I have experimented with.  
 </font>  
   
 <p>  
 For more information about which of these that actually work, read the  
 <a href="intro.html#guestos">section in the Introduction chapter</a>  
 that lists guest operating systems. If a system is not listed there, it  
 probably doesn't work in GXemul.  
   
 <p>  
 <ul>  
   <li>DECstation:  
     <ul>  
       <li><a href="http://www.netbsd.org/Ports/pmax/">NetBSD/pmax</a>:  
         <br><a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-2.0/pmax/binary/kernel/netbsd-INSTALL.gz">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-2.0/pmax/binary/kernel/netbsd-INSTALL.gz</a>  
         <br><a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-2.0/pmax/binary/kernel/netbsd-INSTALL.symbols.gz">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-2.0/pmax/binary/kernel/netbsd-INSTALL.symbols.gz</a>  
         <br>gunzip the files, and run the emulator with <b><tt>-e 3max -q -N -XY2</tt></b>  
         for a graphical framebuffer console. Remove <b><tt>-XY2</tt></b> and <b><tt>-N</tt></b> to use serial (stdin/stdout) console.  
         Read <a href="guestoses.html#netbsdinstall">this section</a> about how to install NetBSD/pmax onto a harddisk image.  
       <p>  
       <li><a href="http://www.openbsd.org/pmax.html">OpenBSD/pmax</a>:  
         <br><a href="ftp://ftp.se.openbsd.org/pub/OpenBSD/2.8/pmax/bsd">ftp://ftp.se.openbsd.org/pub/OpenBSD/2.8/pmax/bsd</a>  
         <br>This is an old OpenBSD kernel in a.out format. Try <b><tt>-e 3max</tt></b>.  
         <br>Read <a href="guestoses.html#openbsdinstall">this section</a> about how to install OpenBSD/pmax onto a harddisk image.  
         It's a bit more complicated than installing NetBSD/pmax, but  
         it usually works.  
       <p>  
       <li>Linux for DECstation:  
         <br>Read <a href="guestoses.html#declinux">this section</a> about how to run a Debian Linux install kernel.  
         <br>Here are some older kernels (these don't support framebuffer, I think):  
                 <a href="http://www.xs4all.nl/~vhouten/mipsel/kernels.html">http://www.xs4all.nl/~vhouten/mipsel/kernels.html</a>  
         <br>Note: Make sure you add <b><tt>-CR4400</tt></b> to the command line for  
                 R4000 kernels, as Linux doesn't autodetect CPU type at runtime.  
         <br>Linux also doesn't detect automatically whether you are booting  
                 in graphical or serial console mode, so you need to add  
                 <tt><b>-o 'console=ttyS3'</b></tt> or similar for serial  
                 console mode.

         <br>Try running with <b><tt>-e ip32 -X</tt></b> for a graphical framebuffer, or  
                 <b><tt>-e ip32 -o 'console=ttyS0'</tt></b> for serial console.  
         <br>Adding <b><tt>-b</tt></b> (bintrans) might work sometimes.  
         <br>(You need to add <b><tt>-CR5000</tt></b> if you're trying to run  
                 a kernel compiled for R5000, because Linux doesn't autodetect

         <br>For some machines, such as <tt><b>-e pica</b></tt>, you can  
                 add <b><tt>-X</tt></b> to boot with a graphical VGA-style  
                 console. This however is probably a bit unstable and/or  
                 broken right now.  
       <p>  
       <li>Windows NT:  
         <br>Put a "Windows NT 4.0 for MIPS" CDROM (or similar) into  
                 your CDROM drive. (On FreeBSD systems, it is usually called  
                 /dev/cd0c or similar. Change that to whatever the CDROM  
                 is called on your system, or the name of a raw .iso image.)  
         <br>I have tried this with the Swedish version, but it might  
                 work with other versions too.<pre>  
         $ <b><tt>dd if=/dev/zero of=winnt_test.img bs=1024 count=1 seek=999000</tt></b>  
         $ <b><tt>gxemul -X -e pica -d winnt_test.img -d bc6:/dev/cd0c -j MIPS\\ARCINST</tt></b>  
         $ <b><tt>gxemul -X -e pica -d winnt_test.img -d bc6:/dev/cd0c -j MIPS\\SETUPLDR</tt></b>  
 </pre>  <br><tt>ARCINST</tt> tries to prepare the disk image for installation. (It <i>almost</i> works.)  
         <br><tt>SETUPLDR</tt> should load some drivers from the cdrom, but then it crashes with a bluescreen.
