With [[Grub| grub2]], you can easily boot a livecd image from your hard drive.
This page lists processor instruction sets that can be enabled on Funtoo Linux systems using the {{c|CPU_FLAGS_*}} variables.

{{fancynote| This is general example. It may not work with all livecds.}}


1. Copy the iso image to root folder for simplicity:
{{TableStart}}
<console>
<tr><th>Flag</th><th>Introduced</th><th>Name</th><th></th></tr>
###i## cp /home/user/downloads/systemrescuecd.iso /src.iso
<tr><td>{{c|mmx}}</td><td>1997 (Pentium MMX)</td><td>MMX</td><td>See [[Wikipedia:MMX (instruction set)]] </td></tr>
</console>
<tr><td>{{c|mmxext}}</td><td>1999</td><td>AMD MMX Extensions</td><td>See [[Wikipedia:Extended MMX]]</td></tr>
 
<tr><td>{{c|sse}}</td><td>1999 (Pentium III)</td><td>Streaming SIMD Extensions (SSE)</td><td>See [[Wikipedia:Streaming SIMD Extensions]]</td></tr>
2. Reboot and when grub2 loads press 'c' for console. Run the following commands (tab autocompletion is your friend):
<tr><td>{{c|sse2}}</td><td>2001 (Pentium 4)</td><td>Streaming SIMD Extensions 2 (SSE2)</td><td>See [[Wikipedia:SSE2]]</td></tr>
<console>
<tr><td>{{c|sse3}}</td><td>2004 (Pentium 4 Prescott)</td><td>Streaming SIMD Extensions 3 (SSE3/PNI)</td><td>See [[Wikipedia:SSE3]]</td></tr>
