| | | ! Description |
| | |
| == /dev/boot2 IOS_Ioctlv == | |
| These ioctlvs do not seem to exist in [[IOS9]]; they may have been added later, or the person writing this may have been confused, since all 3 FS devices register to the same message queue.

| Note: POSIX is a standardized system that helps maintain compatibility between many different operating systems. So, each error code shown below has a given POSIX equivalent (not known yet). Other OS's many have different error code numbers, but if their POSIX equivalent is the same, they mean the same thing.
