<p>Basic IOS article</p> <p><b>New page</b></p><div>&#039;&#039;&#039;IOS&#039;&#039;&#039; (&#039;&#039;&#039;I&#039;&#039;&#039;OP &#039;&#039;&#039;O&#039;&#039;&#039;perating &#039;&#039;&#039;S&#039;&#039;&#039;ystem) is the official firmware running on the [[Wii Hardware/Starlet|Starlet]] (known officially as the IOP) in the [[Wii]]. The distinct software running on the [[Wii U]]&#039;s [[Wii U Hardware/Starbuck|Starbuck]] (also known officially as the IOP) is also known as IOS, but referred to by the community as [[IOSU]] to distinguish it from the Wii&#039;s version.<br /> <br /> Modern versions of [[Wii-Linux]] cannot boot under IOS. Very old versions were able to, but this caused many drivers to be duplicated unnecessarily (to have versions that used IOS IPC calls instead of direct hardware access), and was later removed. [[NPLL]] will automatically reload into [[MINI]] if booted under IOS. [[NetBSD]] can run under IOS (if started with AHB access enabled (HW_AHBPROT=ffffffff)) at the cost of lower available memory (since IOS uses 12MB for itself).</div>
