There are several types of file system media. For example,
the ROM: this is always mapped to drive z:
, and
contains the operating system code
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
c:
.
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 d:
for the first partition on the first CF
device.
Installable file systems may support other media.
