(E) RFGDEMO.PGF
RFGDEMO.PGF This file provides a sample PROGRAM GROUP FILE, which illustrates how to create ROM
pattern files correctly.
The PGF is an ASCII text file that can be created by using any text editor, word processor or DOS <COPY CON>
command. The PGF lists what files will be copied and if DOS is going to be copied. This file can have any DOS
filename, but the extension name must be *.PGF. For example, followings are valid filenames.
RFGDEMO.PGF
MYRFG.PGF
MSDOS.PGF
….
An examples of the *.PGF file is as follow.
ROM_NAME=TEST1 ; ROM pattern file name is TEST1
;The output file names will be TEST1.R01, TEST1.R02..etc.
DOS_DRIVE=C: ; DOS system drive unit is drive C:
;If user does not want to copy DOS
;system files onto the ROM disk
;write as DOS_DRIVE=NONE
ROM_SIZE=128 ;128 means 128KX8 (27C/29F010) EPROM size used
;256 means 512KX8 (27C/29F020) EPROM size used
;512 means 512KX8 (27C/29F040) EPROM size used
;1024 means 1MX8 (27C080) EPROM size used
The following two files are options, which depend on whether the ROM disk is to be bootable, or not.

5.3 WRITE PROTECT FUNCTION
The AR-B1375 and AR-B1376 provide hardware and software write protect functions for small page 5V FLASH
disk and only software write protected function for SRAM disk. This is to prevent your data on 5V FLASH or SRAM
disk from accidental deletion or overwrite. If your FLASH/SRAM disk is write protected, any write operation to the
protected FLASH/SRAM disk will get a write protect error:
