Hard disks
|
|
==========
|
|
|
|
The *Hard disks* page contains settings related to the emulated machine's fixed disks.
|
|
|
|
Hard disk list
|
|
--------------
|
|
|
|
All hard disks attached to the emulated system are listed, with the following information:
|
|
|
|
* **Bus:** bus the disk is attached to, as well as the disk's bus channel/ID. These can be changed through the *Bus* and *Channel*/*ID* boxes below the list.
|
|
* **File:** path to the disk image file.
|
|
* **C/H/S:** the disk's amount of cylinders, heads and sectors, respectively.
|
|
* **MB:** disk size in megabytes.
|
|
|
|
Adding a new disk
|
|
-----------------
|
|
|
|
The *New...* button opens a new window allowing you to create an existing hard disk image file.
|
|
|
|
* **File name:** where to save the disk image file. See :ref:`hardware/diskimages:Hard disk images` for a list of supported image formats.
|
|
* **Cylinders/Heads/Sectors:** CHS parameters for the disk image. These boxes control the *Size (MB)* box below.
|
|
* **Size (MB):** the disk image's size in MB. This box controls the *Cylinders*, *Heads* and *Sectors* boxes above. There are limits to how big a hard disk image can be; see :ref:`hardware/diskimages:Hard disk size limits` for more information.
|
|
* **Bus:** bus to attach the disk to.
|
|
* **Channel**/**ID:** where to attach the disk on the selected bus. The *Channel* value for IDE has two numbers, which correspond to an IDE channel and device, respectively:
|
|
|
|
+---------+-----------+------+
|
|
|*Channel*|IDE channel|Device|
|
|

|
|
|0:1 |Primary |Slave |
|

|
|
|1:0 |Secondary |Master|
|
|

|
|
|1:1 |Secondary |Slave |
|
|
+---------+-----------+------+
|
|
|2:0 |Tertiary |Master|
|
|

|
|
|2:1 |Tertiary |Slave |
|

|3:0 |Quaternary |Master|
|
|
+---------+-----------+------+
|
|
|3:1 |Quaternary |Slave |
|
|

|
|
|
|
Press the *OK* button to create the disk image file, or *Cancel* to close the window.
|
|
|
|
Adding an existing disk
|
|
-----------------------
|
|
|
|
The *Existing...* button opens a similar window to the *New...* button, except that it lets you select an existing disk image file. The CHS parameters are guessed from the image's file size, or the file header if the image is of a format which contains a header.
|
|
|
|
After selecting the image file and checking if the parameters are correct, select the *Bus* and *Channel*/*ID* for the hard disk and press *OK* to add it. Press *Cancel* to close the window.
|
|
|
|
Removing a disk
|
|
---------------
|
|
|
|
Select a disk on the list and press *Remove* to remove it.
