Creative Graphics Blaster RIVA TNT upgrade utility
---------------------------------------------------------------
====================
GENERAL INFORMATION
====================
The Graphics Blaster RIVA TNT BIOS Upgrade utilities consist of the
following files:
* GT2045GC.EXE - BIOS upgrade program
* README .TXT - this readme file
* PATCH\PT2045GC.EXE - Patch BIOS upgrade program
=============
KNOWN ISSUES
=============
I. Running a Direct3D game on some ASUS motherboards causes the system to hang.
On the ASUS P2L97 rev. 1.05 and P2L97-DS rev. 1.03 motherboards, the AGP
sidebanding bus protocol that allows a graphics card to access system
memory in a Direct3D game or application is broken. We provide a patch
that disables the sideband protocol and allows Direct3D applications to
run normally, with some performance degradation depending on the
application.
Please use the BIOS located in the \PATCH directory.
II. The Graphics Blaster RIVA TNT hangs at the video bios screen.
When the Graphics Blaster RIVA TNT is used on certain systems, it is
possible that the Graphics Blaster RIVA TNT will hang at the video bios
screen upon boot. If you are experiencing a symptom similar to this, you
will need to install a temporary video card to run the patch bios update.
To run the patch in this situation, do the following:
1. Move the Graphics Blaster RIVA TNT to the lowest priority (highest number)
pci slot.
2. Install a temporary video card into the highest priority (lowest number)
pci slot.
3. Boot to NATIVE DOS. (see below)
4. Run the GT2045GC.EXE patch bios update. (see below)
5. Once the patch update is completed, shut down the system and remove the
temporary video card. Then, move the Graphics Blaster Riva TNT to the
original PCI slot and reboot. The GB RIVA TNT should be updated and
functioning properly.
======================
STEPS TO UPGRADE BIOS
======================
1. Determine if your video BIOS has the latest update by looking at the
version number displayed during system bootup.
If your version is newer, you do not need to upgrade your BIOS.
Otherwise, proceed with the following steps.
2. Boot to native DOS, and run the BIOS upgrade program GT2045GC.EXE.
Note: Due to the nature of Windows environment, this program has to be
run in native DOS mode. If you do not know how to boot up your system
in native DOS mode, refer to the section below on "BOOT TO NATIVE DOS
MODE".
3. Press <F> to flash the new BIOS into your Graphics Blaster RIVA TNT.
Note: The programming process takes about 10 seconds (including
verification time) to complete.
WARNING: Do NOT interrupt this process. Interrupting this process
may result in unexpected (and undesirable) consequences.
When the program displays the message, "BIOS successfully flashed",
this means that the VGA BIOS on your Graphics Blaster RIVA TNT is
upgraded.
4. After the new BIOS is successfully flashed, reboot your system.
The system should now boot up with the updated Graphics Blaster
RIVA TNT BIOS (verified by the new version number displayed
during bootup).
=========================
BOOT TO NATIVE DOS MODE
=========================
The following are two methods of booting your system to native DOS mode:
Method 1 - Using a bootable diskette
1. Insert an unused diskette into your floppy disk drive A.
2. At the command prompt, type "FORMAT A: /S" to create a bootable diskette.
3. Leave the diskette in the drive and reboot your system.
This boots your system to native DOS mode.
Method 2 - Using the <F8> key
1. Reboot your system, paying attention to the on-screen initialisation
messages.
2. When you see the text "Starting Windows 95...", press the <F8> key
within 5 seconds.
A menu appears.
3. On the menu, select the option "Command prompt only" to reboot the
system to native DOS mode.
