Removable/detachable operating system

An OS module enabled for interconnection with a computer and removable therefrom, the OS module comprising components including:

• a data signal gate, a write control device, a first memory device, and a second memory device;
• the first memory device holding portions of an OS that are unchanged during startup and operation of the computer;
• the second memory device holding portions of the OS that may be changed during startup and operation of the computer;
• the components interconnected for data signal flow between the computer and the second memory device through the data signal gate, and further interconnected for data signal flow between the computer and the first memory device through the data signal gate and the write control device.

A computer system including an OS module enabled for insertion into, and removal from operating circuits of the computer system, the OS module comprising components including:

• a data signal gate, a write control device, a first memory device, and a second memory device;
• the first memory device holding portions of an OS that are unchanged during startup and operation of the computer;
• the second memory device holding portions of the OS that may be changed during startup and operation of the computer;
• the components interconnected for data signal flow between the computer and the second memory device through the data signal gate, and further interconnected for data signal flow between the computer and the first memory device through the data signal gate and the write control device.

A computer system including an OS module engaged with operating circuits of the computer system, the OS module comprising components including:

• a data signal gate, a write control device, a first memory device in the operating circuits, and a second memory device not in the operating circuits;
• the first memory device holding portions of an OS that are unchanged during startup and operation of the computer;
• the second memory device holding portions of the OS that may be changed during startup and operation of the computer;
• the components interconnected for data signal flow between the computer and the second memory device through the data signal gate, and further interconnected for data signal flow between the computer and the first memory device through the data signal gate and the write control device.

A method of separating an OS of a computer into a portion that remains unchanged in a first drive memory during startup and operation of the computer, and a portion that may be changed in a second drive memory during startup and operation of the computer;

• the method comprising the steps of:
• a) open the bios screen presenting user options;
• b) write the entire OS of the computer to the first drive memory;
• c) write protect the first drive memory;
• d) write only a user changeable portion of the OS from the first drive memory to the second drive memory.
