IOS30 was used by System Menu 3.0, 3.1, 3.2 and 3.3. Changes from IOS28 include adding an $IOSVersion tag to every module, as well as changing DVDLowUnencryptedRead to allow two other areas to be loaded; these areas are used to detect drivechips and show error 001. IOS30 also added USB Keyboard support through a KBD module, but this was not used until v1040 despite being present in v1037.
Like IOS28, IOS30 has a mechanism to block access to certain devices from the Broadway. However, instead of continuing the search as if the device does not exist, IOS_Open in IOS30 returns -1 if the device blocks access.
Together with IOS16, IOS31, and IOS37, IOS30 did not have its ES_Identify and /dev/flash access fixed with 3.3rev03. With the exception of IOS16, which got stubbed in 4.0, all of these were fixed in 3.4.
