IOP (Physical I/O to Disk)
IOP allows you to read or write blocks of data, or to format the specified
device in a certain way. IOP creates a command packet from the
arguments you have specified, and then invokes the proper system call
function to carry out the operation.
IOT (I/O Teach)
IOT allows you to change any configurable parameters and attributes of
the device. In addition, it allows you to see the controllers available in the
system.
IOC (I/O Control)
IOC allows you to send command packets as defined by the particular
controller directly. IOC can also be used to look at the resultant device
packet after using the IOP command.
BO (Bootstrap Operating System)
BO reads an operating system or control program from the specified
device into memory, and then transfers control to it.
BH (Bootstrap and Halt)
BH reads an operating system or control program from a specified device
into memory, and then returns control to the 162Bug. It is used as a
debugging tool.
Disk I/O via 162Bug System Calls
All operations that actually access the disk are done directly or indirectly
by the 162Bug TRAP #15 system calls (the command-level disk
operations provide a convenient way of using these system calls without
writing and executing a program).
