stated in your PGF). The ROM pattern files will have the same file names, but will have different extension
names. For example:
TEST.R01, TEST.R02, TEST.R03…etc.
Display Error in PGF File
This option displays errors that were detected in your PGF.
Help to PGF File
This option gives information on how to write a PGF file and how to generate ROM pattern files. An
example PGF is also included.
Move the reverse video bar to <Generate ROM File(s)> then press [ENTER]. The ROM pattern file is a
binary file. The file size will be the same size as the EPROM that you assigned in the PGF. For example, if
you are using 128KX8 EPROM memory chips, then the size of ROM patterns file will be 131072 bytes. For
other chips the file size will be:
64KX8 EPROM----65536 bytes
256KX8 EPROM—262144 bytes
512KX8 EPROM---524288 bytes
1MX8 EPROM -----1048576 bytes
(6) 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.
CONFIG.SYS
AUTOEXEC.BAT
;Below are user’ s files
A:\USER1.COM ; File USER1.COM on root of drive A:
USER2.EXE ; File USER2.EXE on current directory & drive
