(2) WD1474.EXE

 

WD1474.EXE

This program demonstrates how to enable and trigger the watchdog timer. It allows you to

 

test the <TIMES-OUT & RESET> function when the watchdog timer is enabled.

(3) WP1474.EXE

 

WP1474.EXE

This program demonstrates how to enable and disable software write protected function. It

 

also shows the current protect mode of write or read only memory.

(4) BU1474.EXE

 

BU1474.EXE

BU1474.EXE is used to update the SSD BIOS conveniently if the SSD BIOS need to be

 

revised. This program will erase the BIOS ROM and reprogram with revised BIOS.

(5) RFG.EXE

 

RFG.EXE

This program is used to generate ROM pattern files in a binary format. Each ROM pattern file

 

has the same size as the FLASH or EPROM and can be easily programmed on to the FLASH

 

with on-board programmer or on to EPROM with any EPROM programmer. If you have

 

specified a DOS drive in the *.PGF file, RFG will generate bootable ROM pattern files for the

 

EPROM or FLASH disk. The RFG supports the following DOS: MS-DOS, PC-DOS, DR-DOS,

 

and X-DOS.

NOTE: If you want to use AR-B1474 with any DOS which is not supported by RFG, please send your requirement to Acrosser Technology Co., Ltd. or contract with your local sales representative.

The RFG.EXE provided in the utility diskette is a program that converts the files you list in the PGF and convert them into ROM pattern file. The RFG will determine how many EPROMs are needed and generate the same number of ROM pattern files. These ROM pattern files are named with the name assigned by the ROM_NAME in the PGF and the extension names are *.R01, *.R02 … .etc. To generate ROM pattern files.

The ROM File Generator main menu will be displayed on the screen. There are 7 options on the main menu. They serve the following functions:

Quit to DOS

Quits and exits to the DOS

OS Shell

Exits from the RFG temporarily to the DOS prompt. Type <EXIT> to return to the RFG main menu.

Load PFG File

If this option is used, the RFG will prompt you for the PGF file name. This option is useful if you have not previously entered a PGF name or you wish to use a different PGF file. The RFG will check and display the PGF filename, ROM pattern file name, EPROM capacity, DOS version and the number of ROM pattern files that will be generated.

Type Current PGF File

This option instructs the RFG to use the DOS type command to display the contents of the current PGF file.

Generate ROM File(s)

If there is no mistake in your *.PGF file, then this menu option will generate ROM pattern files. The number of ROM pattern file generated by the RFG will depend on the total capacity needed by your files. For instance, if 3 files are generated, then you will need to use 3 EPROMs (The size depends upon the number

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.
