Use this view of the Device Definition window to view, modify, and create DOS disk volume definitions (sometimes called DOS Drives).
For more information about the general subject of device definitions, managing them, and interacting with the controls that are common to all views of the Device Definition window, see About Device Definition.
DOS drives include any physical DOS partitions available on your system as well as virtual disk volumes. The list of token names can be used to select a particular volume in order to view or modify its configuration parameters.
The tokens are named dosc, dosd, and so on, to correspond to the drive descriptions Native DOS c: and Native DOS d:, respectively. By default, if the DOS drives are not already readable and writeable by all users then the definitions are restricted to be for "root" user use only. To make a physical DOS partition available for general use, you need to change the definition's Usable By setting from "Root" to "All".
Note: When you change the "Usable By" setting of a real DOS partition from "Root" to "All", Win4Lin also changes the Linux permissions on the device file so that every user has permission to read and write it.
If for some reason a DOS drive definition for a physical DOS partition does not get automatically created by Win4Lin, then you can create a new drive definition for the DOS partition. To do this you generally follow the steps in the following section "Creating a New Virtual Disk Volume", but instead of specifying a normal filename you specify the Linux device name for the partition.
You can modify the attributes of any DOS drive using this window. See Modifying Volume Attributes.
You can also create new virtual disk volumes. See Creating a New Virtual Disk Volume.
Creating a New Virtual Disk Volume
To create a new virtual disk volume, follow these steps:
Another window is displayed in which you can specify the volume's size and the type of access that other users can have to the volume. After you specify the needed information, you are returned to this window.
Individual users cannot relax the access attributes that are specified here. However, they can further restrict the access attributes, if they choose, when they attach this volume to their DOS or Windows sessions through the Personal Win4Lin Session Configuration window.
DOS and Windows sessions that attach this volume can read files on the volume, but cannot update, create, or delete them.
DOS and Windows sessions have exclusive use of this volume. Only one session at a time can attach it successfully.
Only one DOS or Windows session can attach this volume at a time. Applications running in that session can read the files on the volume, but not update, create, or delete them.
Multiple DOS and Windows sessions can read, update, create, and delete files on this volume at the same time.
