Deleting Data On An Sram Card; Using Flash Memory Cards - Advantech PCM-3110 Manual

Note that you must transfer the system using the format command and
cannot use the SYS command to transfer the system to a pre-formatted
SRAM card as you can with a floppy diskette.
After transferring the system to the card with the FORMAT command,
you must then copy the PC/104 PCMCIA Module drivers and the DOS
files HIMEM.SYS and SETVER.EXE from your internal hard disk
drive to the SRAM card. Create a CONFIG.SYS file on the card which
loads the PC/104 PCMCIA Module drivers and includes the other
statements necessary to load HIMEM.SYS and SETVER.EXE, and set
DOS = HIGH with UMBs, as detailed in Chapter 3. If you do not do
this, though you will be able to boot from the SRAM card, the PC/104
PCMCIA Module slots will not be activated for any other device since
the drivers that are needed to enable the system to recognize PC/104
PCMCIA Module have not been loaded.

Deleting Data on an SRAM Card

You can copy data to and delete data from SRAM cards as many times
as you want using the standard DOS COPY and DELETE commands.
Since SRAM cards are formatted with the DOS FAT system, they
function exactly like floppy diskettes and there is no restriction on
deleting data from them.

Using Flash Memory Cards

Using the DOS File Allocation Table (FAT) is very rough and is not a
very useful or efficient way of formatting Flash memory cards. Most
users find that using specialized software (like CardWizard,
CardSoft, CardWorks) or the Flash File System (FFS) is a much
better way to format their cards.
Flash memory cards can be formatted to be both readable and writable.
This is done by using using the MCFORMAT.EXE utility program that
is provided with your PC/104 PCMCIA Module unit.
CardWizard includes specialty software called File Translation Layer
(FTL) that can format Flash cards and make them readable and writ-
able.
