JANUS 2050 Vehicle-Mount Computer User's Manual (4MB)
An SRAM disk is specified in the factory installed CONFIG.SYS file. If you
reconfigure SRAMDISK.SYS or change the RAM size, the RAM drive initializes
and destroys any previous drive. Before reconfiguring this drive save all
important data files.
Note: Files on the RAM drive are not retained when you execute a cold boot on the
JANUS 2050.
To create or change the SRAM drive
1. Verify that HIMEM.SYS or another extended memory manager is loaded in
2. Edit the JANUS 2050 CONFIG.SYS file. It is easier to edit the CONFIG.SYS
3. Include a separate SRAMDISK.SYS command line in your CONFIG.SYS file
4. Initiate a warm boot on the JANUS 2050 by pressing c a f . in

for each SRAM disk you want to add. The SRAMDISK.SYS command
line(s) must be added after the line that loads the extended memory
manager. The command syntax is:
device={ drive: }{ path }sramdisk.sys { DiskSize SectorSize
NumEntries }
where:
drive:path specifies the location of the SRAMDISK.SYS file.
DiskSize specifies the size in kilobytes (K) of the SRAM disk. The size can
range from 16K to 256K. The default is 64K.
SectorSize specifies the disk sector size in bytes. The size can be 128, 256, or
512 bytes. The default is 512. If you include a SectorSize value, you also
need to include the DiskSize value.
NumEntries specifies the number of files and directories that can be created
in the SRAM disk directory. You can specify from 2 to 1024 files and/or
directories. The default is 64. If you include a NumEntries value, you must
also include the SectorSize and DiskSize values.
