86 OMNI 37XX REFERENCE MANUAL
In a typical download procedure, all files are loaded into the RAM file system of
the target group selected in system mode. Specific files included in the download
package must be redirected, as necessary, to the flash file system of the target
group or to the RAM or flash file system of another file group.
To redirect files during a download procedure, see the following sections.
Defragment Flash For Application Downloads
Before you perform an application download, you may need to defragment
terminal flash memory. For information on performing this system mode
operation, see System Mode Menu 2.
To ensure the best result when performing back-to-back downloads, you may
need to defragment the flash memory of both the sending
and receiving terminals.
A system mode procedure is also available for clearing the RAM or flash memory,
either entirely or for a specific file group, to prepare an Omni 37xx for a
clean
download.
Redirection of
Files During
Application
Downloads
You can download application files into RAM or flash memory. By default, files
that you download to a specific file group are stored in the RAM of that group. To
store a file in flash of that file group, you must provide instructions to redirect the
file to flash as part of the procedure.
There are two methods you can use to redirect files during an application
download, depending on the download tool you are using:
• If you are using Download Manager or VeriCentre, you must manually create
and include special zero-length files called SETDRIVE.x and SETGROUP.n
on the download computer, and add these files to the batch download list to
direct files to a specific file system (drive) or file group.
• If you are using DDL.EXE to perform direct downloads, you can use a special
command-line option that automatically redirects files to the drive and file
group you specify.
Both of these methods are described in the following sections.
Manually Redirecting Files to Flash Memory
To manually redirect files to flash memory for Download Manager or VeriCentre
application downloads, you must create one or more files on the download
computer with the special file name, SETDRIVE.x, where,
x is the name of the
drive (memory area) to download files to:
• Drive name I: is RAM: This is the system mode default for downloads.
• Drive name F: is flash.
NOTE
The flash defragment operation is not necessary for an Omni 37xx terminal just
out of the box. In this case, the terminal flash file system is still in its factory-new
condition.
