software control in the application program in consideration of the hardware upgrading.
One easiest way to utilize the NVSRAM of a Jiva SL (TP5700) & Jiva EL (TP5800)
system is through the use of appropriate software driver to simulate a disk drive.
To have the NVSRAM work as a simulated disk drive, the user should first
simply download from web page http://www.posiflex.com.tw/english/download.htm
the file NDISK.SYS in Jiva SL (TP5700) & Jiva EL (TP5800) driver utility to a
convenient directory of his/her Hard Disk Drive, say copy the file NDISK.SYS to the
subdirectory C:\PATH where PATH means the subdirectory routing required, add
following sentence into the CONFIG.SYS file:
DEVICE = C:\PATH \ NDISK.SYS or
DEVICEHIGH = C:\PATH \ NDISK.SYS
and then restart the system. This will give a simulated free disk space of 28,160 bytes
after restart of the system.
The NVSRAM will then work as a simulated disk drive D: which works not
only faster than a hard disk drive but also more reliable and safer especially in case of
power failure.
