<p>There are several types of file system media. For example,</p>
<ul>
<li id="GUID-7E4E072F-11FF-5C54-BAE2-59AB9F1B68A5"><p>the ROM: this is always
mapped to drive <filepath>z:</filepath>, and contains the operating system
code</p> </li>
<li id="GUID-73A8A963-AEFE-5B2C-9F28-3691232B15BB"><p>the RAM: a RAM drive
shares space with kernel and user program memory. This space is dynamically
allocated: there is no need for the owner of the machine to pre-allocate space.
The RAM drive is always mapped to drive <filepath>c:</filepath>.</p> </li>
<li id="GUID-54FE9E36-7197-5F7A-8AE3-746BA39BE548"><p>compact flash, accessed
through an ATA interface: this is the main supported removable media. Whether
there is a CF card slot, and what drive letters are allocated to it, are implementation
dependent. A typical choice would be to use <filepath>d:</filepath> for the
first partition on the first CF device.</p> </li>
</ul>
<p>Installable file systems may support other media.</p>
