Disk I/O via 187Bug Commands

These following 187Bug commands are provided for disk I/O. Detailed instructions for their use are found in the Debugging Package for Motorola 88K RISC CPUs User's Manual. When a command is issued to a particular controller LUN and device LUN, these LUNs are remembered by 187Bug so that the next disk command defaults to use the same controller and device.

IOI (Input/Output Inquiry)

This command is used to probe the system for all possible CLUN/DLUN combinations and display inquiry data for devices which support it. The device descriptor table only has space for 16 device descriptors; with the IOI command, you can view the table and clear it if necessary.

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.
