114 <h2>Going further</h2>
115
116 <p>Tiny SliTaz should be smaller to have more functionality and/or needs less
117 RAM.<br>
118 The kernel can be <a href="http://elinux.org/Linux_Tiny">tuned/patched</a> or
119 you can use an earlier version.</p>
120
121 <p>You can test Tiny SliTaz without pre-historic hardware using qemu (needs the
122 <tt>ne.ko</tt> module):</p>
123
124 <pre>
125 qemu -cpu 486 -m 4 -net nic,model=ne2k_isa -net tap -fda slitaz.img
126 </pre>

131 qemu -cpu 486 -m 4 -net nic,model=ne2k_isa -net tap -kernel kernel -initrd rootfs.gz /dev/null
132 </pre>
133
134 <p>And the executable file <code>/etc/qemu-ifup</code>:</p>
