 ====== Switching Images between i586 and x86_64 ======
-Beginning with SVN r7353 and officially with AstLinux 1.2.5, two new board types were added: genx86_64 and genx86_64-serial.  These boards are x86_64 builds using a 64-bit toolchain, initrd and Linux kernel.
+Beginning with AstLinux 1.2.5, two new board types were added: genx86_64 and genx86_64-serial.  These boards are x86_64 builds using a 64-bit toolchain, initrd and Linux kernel.
 In general, users will be advised to choose either a geni586[-serial] or genx86_64[-serial] install image and stick with that board type, but developers may want to take a shortcut and switch between i586 and x86_64.
