7.23 JumpDrive Device

The purpose of the JumpDrive device is to allow easy import and export of data between a host system and a simulation environment. You can import files from the host system on to the JumpDrive, where they will be accessible by the simulated operating system. Data can also be exported from the JumpDrive back to the host system after the simulation ended.

The image file used by the JumpDrive is very different from any other image files that the simulator supports. The only image files that can be loaded are those image files that are saved by the JumpDrive itself.

Section A.7.26, “JumpDrive”, on page 247 describes the JumpDrives automation commands.

Interface

The JumpDrive device has an USB interface that can connect to any USB controller, e.g., you can connect the JumpDrive device to the AMD-8111 I/O Hub.

Initialization and Reset State

The JumpDrives initialized state is all zero. There is no partition table or any other structure defined. It is totally blank. The default size is 64 Mbytes. The JumpDrive is not modified after a reset.

Contents of a BSD

The JumpDrive device saves its entire state, including the contents of its memory, to the BSD. Any data that exists on the JumpDrive device will be restored when the BSD is reloaded.

Configuration Options

Most of the automation commands will return an error if the JumpDrive is "plugged into" the simulated computer, i.e., if the JumpDrive device is connected to a USB controller. The device must be "not connected", i.e., unplugged, to issue commands that alter the JumpDrive image.
