Nintendo has released a new version of [[Boot1]], which disables Bootmii as a [[Boot2]] hack. Fortunately, Bootmii can also be modified to work as a replacement for IOS, or as a separate IOS (Hypothetically, [[IOS5]]). See more at [http://hackmii.com/2009/02/bootmii-and-the-new-boot1/ Hackmii]. Since boot1 cannot be updated, all consoles already manufactured before this update are safe. About 10% of the consoles that ran the BootMii Checker tool have the new boot1.
