Drive Lettering - Symbol PTC-870IM User Manual

The documentation provided with
the Telxon Pen-based 11x4 Series
Software Development Kit contains
information on creating a RAMdisk
or expanded memory.
The PCMCIA slot is not user
accessible.
Data stored in RAM can be easily read, written, and
changed, but it is also volatile. All data in RAM
(including the RAMdisk) will be lost if power to the
unit is disconnected and the bridge battery runs out
of power.
During normal operation, the PTC's sleep/resume
feature automatically saves data in RAM and saves
your place in the application.
You may also be able to use some or all of the RAM
above 1 MB as expanded memory using a LIM EMS
4.0 driver.
Refer to the "Drive lettering" section below for the
drive letter assignments.

Drive lettering

The PTC-870IM's operating system identifies an
internal PCMCIA slot, a ROMdisk, a RAMdisk, and a
hard drive by assigning them drive letters as follows:
•
Drives A and B are the internal PCMCIA slot.
•
The ROMdisk (the application flash EPROM) is
drive C, unless a RAMdisk has been created.
•
If a RAMdisk exists, the RAMdisk is drive C, and
the ROMdisk is drive D.
•
If a hard drive is installed, it always receives the
last drive letter. If no RAMdisk exists, the hard
drive is D. If there is a RAMdisk, the hard drive
is E.
