Creating A Ram Drive - Intermec Janus 2050 User Manual

You can use these utilities to create an image file and copy it to drive C:
Auto-Loader Auto-Loader creates an image file that contains the files you want
placed on drive C, and then replaces the old drive C image file with the new
one. You run Auto-Loader on a host computer connected to the COM1 port on
the JANUS device.
Binary file transfer (BFT) Use BFT in a 900 MHz CrossBar or RF network to
connect a host computer to one or more devices in order to transfer binary files
of change the contents of drive C. For help, see "Communicating With the
JANUS 2050" in Chapter 6.
MakeDisk and PutDisk MakeDisk creates an image file containing the files you
want on the drive, and PutDisk places the new image on the JANUS drive.
MakeDisk supports the creation of subdirectories on drives C and D. For more
information, see "Using MakeDisk and PutDisk to Change Drives C or D" later
in this chapter.
When deciding which utility to use, you should consider these facts:
• Auto-Loader and BFT require you to use a host computer. MakeDisk and
• You must install Auto-Loader onto the host computer. MakeDisk and
• You must create a BFT application for the host computer using Data
• If you run MakeDisk on the reader's RAM drive, the image file must be less

Creating a RAM Drive

The device driver SRAMDISK.SYS is used to create an SRAM (static random
access memory) drive E on the JANUS 2050. SRAM disks are faster than hard
disk drives because the data is always loaded into RAM. The number of SRAM
disks you set up is only limited by the amount of memory in the JANUS 2050.
SRAMDISK.SYS only works in extended memory (above 1MB). It cannot use
conventional or expanded memory. For SRAMDISK.SYS to use extended
memory, HIMEM.SYS or another extended memory manager that conforms to
XMS must be installed. In the CONFIG.SYS file, the device command that
installs the XMS extended memory manager must precede the command that
installs the SRAM disk. SRAMDISK is compatible with all DOS commands and
Norton utilities.
