RAMBIOS device driver:

- RAMBIOS SYS ...a program to speed up video read and write operation.

Put DEVICE=RAMBIOS.SYS as the first device driver command in CONFIG.SYS
file. It should be installed before any other device driver in order to be
compatible with most application programs.

- RAMBIOS EXE ...a program for AUTOEXEC.BAT or under dos prompt.

UANSI device driver:

- UANSI SYS enhanced standard input and standard output
device driver

Include DEVICE=UANSI.SYS in CONFIG.SYS file. This command causes DOS
to replace the standard input and output support by the extended
SuperVGA features.

SMOOTH/JUMP scrolling utility:

- SMOOTH COM ...smooth scrolling
- JUMP COM ...jump scrolling

To obtain a better result, system speed should be 8 MHz or up. Type
"smooth" at DOS prompt, the display will be changed to smooth scrolling
screen, or type "jump" at the DOS prompt, display will be toggled to
jump scroll when speed is preferred.

ENABLE16/ENABLE8 16 or 8 bits enable utility:

- ENABLE16 COM ...enable 16 bits read/write on the text mode.
- ENABLE8 COM ...enable 8 bite read/write on the text mode.

To obtain a better result, system will be under 16 bits R/W. If it is
concerned with the compatibility to IBM standard VGA, the 8 bits R/W
to obtain a better result.

VESA Mode Monitor device driver:

- VMODE COM ... a TSR program to set vertical refresh rate


1) VMODE select VESA (70Hz) mode

2) VMODE -i select ISO (75Hz) mode

Set mode and Diagnostic utility:

- UVGA EXE ...a menu driven mode switching utility

This set mode and diagnostic program allows you to select and preview
any mode that is available to your configuration. You may run this
program either directly from the DOS prompt or from a menu.


Type this command at the DOS prompt, you are entering a menu-
driven set mode program. There are six menus, and you will be
entering one of these menus depending on the monitor and the
switch setting of the SuperVGA adapter.

For instance GVGA -V13 , you are entering the 320x200
256-color graphics mode.
To return to the default mode use: UVGA -V3

All the backward compatibility support, including MDA/Hercules,
CGA and CDOS (Chinese applications based on Hercules), are listed
in each UVGA menu. These features can be enabled by either using
the syntax mentioned above or simply enter AON (Auto Display ON)
or AOFF (Auto Display OFF) to enable or disable all backward

4) UVGA [60,70,6,7]
The Flicker-Free feature in the UVGA increases the vertical
refresh rate of 640x480 mode from 60 Hz to 70 Hz.

5) UVGA [R0,R1,R2,R3,R4,R5,R6,R7,R8]
For monitor-reference type select which
R0 : SONY 1302
R1 : SONY 1304
R2 : NANOA 8060
R3 : NANOA 9070
R4 : NEC 2A
R6 : NEC 3D
R7 : NEC 4D
R8 : IBM 85xx

UVGA.EXE support a function for saving setting-monitor-type
At UVGA.EXE main menu, press F10 and 'Y'.

Extended clear screen utility:

- CLEAR COM ...clear screen function for UM85C408 extended mode

The DOS 4.0 clear screen command, CLS only clears a portion of the screen
under extended modes. For DOS 4.0 users, please use CLEAR.COM instead of
CLS to clear the whole screen.

Copy this file, CLEAR.COM, to the root directory of your boot drive,
and set a PATH to root. Therefore, you can use CLEAR.COM wherever
you want to.
