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

C:\TTT\USER3.TXT

; File USER3.TXT on sub-directory TTT of drive C:

DX4, AR-B1474, 486DX specifications

The Sony 486DX, AR-B1474, and DX4 are notable examples of advanced computing technologies from the early to mid-1990s, a time when personal computers were rapidly evolving to meet increasing user demands. These systems played a pivotal role in shaping the landscape of modern computing.

The Sony 486DX is built around the popular Intel 80486 microprocessor, which was a significant step up from its predecessor, the 386. The 486DX featured a 32-bit architecture and introduced integrated cache memory, which greatly enhanced data processing speeds and overall system performance. Operating at clock speeds typically ranging from 25 to 100 MHz, the 486DX models provided a solid foundation for running more sophisticated software applications and advanced games of the era.

Accompanying the 486DX was the AR-B1474 motherboard, designed to maximize the potential of the 486 architecture. This motherboard featured support for up to 512 KB of level 2 cache memory, further boosting performance for data-heavy tasks. The AR-B1474 also included extensive connectivity options, with ISA slots for legacy devices, as well as support for EISA, making it compatible with a wide range of hardware peripherals. This versatility made the AR-B1474 a popular choice among builders of custom desktop PCs during its time.

The DX4, another significant milestone, built upon the 486 architecture by introducing a clock-doubling technique. By effectively allowing the processor to perform operations at up to three times its base clock speed (typically 75 or 100 MHz), the DX4 could handle even more demanding applications, thereby providing users with significant performance improvements without requiring a complete overhaul of their systems.

Both the 486DX and DX4 processors facilitated advancements in multimedia capabilities, with improved graphics rendering and audio performance that supported CD-ROMs and early gaming technologies. This made them particularly appealing to consumers looking for a versatile machine for both work and entertainment.

Overall, the combination of the Sony 486DX, AR-B1474 motherboard, and DX4 processor exemplifies a significant chapter in computing history, showcasing how hardware advancements seamlessly integrated with user needs for performance and flexibility. As these technologies laid the groundwork for future innovations, they remain noteworthy for their contributions to the evolution of personal computing.
