This IOS contains the [[NAND Boot Program]]; it seems to be a slightly modified version of v1.21 that patches the Internet Channel.

This IOS contains the [[NAND Boot Program]]; it seems to be a slightly modified version of v1.21 that patches the Internet Channel. This version is loaded whenever HADJ, HADE, or HADP is loaded, and the content itself is located by searching for the first content with more than 0x400 bytes. This code is only capable of loading private contents, which is why the boot program is not in [[:/shared1]].

In the past, this IOS was often used by homebrew, as it is one of the only known IOSes that is safe to downgrade on [[RVL-CPU-20]] Wiis. It was then used to patch the [[signing bug]] back into newer IOSes, like [[IOS36]].
