The Mobile I/O driver has been updated to a Universal Binary and runs Native on both the Intel and PowerPC platforms. The version number of this driver is 2.2d94. MIO Console has been tested under Rosetta, and currently runs translated on the Intel-based Macs. This version of the driver supports all Macs running Mac OS X 10.3.9 and newer (both Intel and PowerPC).
A point you should note is that that Mac OS X 10.4.4 for Intel has a bug in Firewire that will cause a Kernel Panic if you run MIO Console with a box attached. As a result, users must update their OS install to 10.4.5 on Intel-based Macintoshes to utilize MIO Console.
