 * Port it on real hardware and make some cool demos - after we get full OpenVZ support

-* fix compilation on x86_64 boxes by compiling everything in 64bit mode. We need a 64bit hardware anyway since the SVM instructions are available only on recent 64 bit boxes so this shouldn't matter too much, except for some extra wasted ROM space caused by the 64bit code. We can't cross-compile because we're not using a full toolchain, like buildroot does - non-issue anymore, after we switched to buildroot

 === How to build ===
-Choose the version you want to use by using eithret of the "make openvz" or "make kvm" commands. '''Currently KVM is broken, and OpenVZ works but lacks the vzctl utility(whic is currently in progress).'''
+Choose the version you want to use by using either of the "make openvz" or "make kvm" commands. '''Currently KVM is broken, and OpenVZ works but lacks the vzctl utility(whic is currently in progress).'''
 Just type ''make'' and everything should get built just fine.
 (Optional step) If you wish to make some adjustments you may do it by running one of these commands, but normally you shouldn't need to do this:
   make buildrom-config
   make buildroot-config

 === Needed tools ===
-First of all, you need a x86 Linux distribution with gcc > 4.2, since currently the build fails under x86-64 and gcc-3.x doesn't support some compiler flags we are using. Eventually this will get fixed in the future.
+First of all, you need a modern Linux distribution capable of running buildroot and buildrom (anything with gcc > 4.2 should do).
 In order to build this stuff you need a build system consisting of forked versions of [[buildrom]] and [http://buildroot.uclibc.org/ buildroot] that can be cloned from my git repo using this command:
   git clone http://repo.or.cz/r/avatt.git
-You also need to have installed some of the [http://www.coreboot.org/Buildrom#Prerequisites prerequisites of buildrom], and maybe even others that may be missing from your box. I'll eventually make a list of needed tools for common distros...
