Speed profiles

The *Speed* box below the hard disk list controls the **emulated speed profile** for the selected disk. Speed emulation takes the rotation speed, physical layout and cache size of an average period-correct drive into account. The **RAM Disk** profile runs the drive as fast as the host can manage.
The special **Conner** profiles are specifically designed to get around the :ref:`GRiDcase 1520 <grid1520>`'s hard disk model restriction, and should not be used on any other machines.
.. note:: Speed profiles are currently only available for **IDE** and **ESDI** hard disks. The RAM Disk profile is always used on other disk types.
The *Model* box below the hard disk list determines the **disk model** to emulate. Model profiles adjust the disk's identification data, as well as its performance according to rotation speed, physical layout and cache size. Generic profiles adjust performance to match an average period-correct disk, while the **RAM Disk** profile runs the disk as fast as the host can manage.

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.
