1. Download the 45.28 driver from NVIDIA :

45.28_win2kxp

and Unpack this file to a directory,for example -- c:\45.28

2. Create a dir name "MOD",for example -- c:\MOD

3. Copy these 3 files from c:\45.28 to c:\MOD
nv4_mini.sy_
nv4_disp.dl_
nvoglnt.dl_

4. Copy the Unpack.bat (which Rui made) to c:\MOD, and run it.
unpack.bat is simply:
expand nv4_mini.sy_ nv4_mini.sys
expand nv4_disp.dl_ nv4_disp.dll
expand nvoglnt.dl_ nvoglnt.dll

( Download unpack.bat and nv4_disp.inf here: MOD.zip)

5. In c:\MOD, delete
nv4_mini.sy_
nv4_disp.dl_
nvoglnt.dl_

6. Run RivaTuner
PowerUser --> Open Patch Script
Apply these four scripts:

* Softquadro4
* NV Strap Antiprotector
* AnisoBoosterOpenGL
* DetonatorFXAntiprotector

When the script ask for the location of the driver, just point to c:\MOD

7. In c:\MOD, del *.old ,and rename the rest:
nv4_mini.sys => nv4_mini.sy_
nv4_disp.dll => nv4_disp.dl_
nvoglnt.dll => nvoglnt.dl_

After that, copy them to c:\45.28, replacing the original files

8. Copy nv4_disp.inf to c:\45.28, replacing the original one.
(Allows 45.28 drivers to recognize the 5900XT - find it in modstep.zip listed in step 4.)

9. Download a 60.xx driver from guru3d, install it (run exe), reboot ,uninstall it, reboot., Your system is back to VGA mode.

10. In the moded driver dir c:\45.28, run setup.exe to install 45.28 driver, reboot.

11. Run RivaTuner, install NVStrap, but do not reboot. In NVStrap, Change the PCI Device ID to Custom --> 0338 Quadro 3000. Reboot.

12. When Windows asks to install a driver for Quadro 3000, press cancel.

13. In c:\45.28, run setup.exe, again, reboot.

14. Go to Display Properties -> Settings -> Advanced -> Nvidia panel -> Open GL Settings -> Vsync OFF by default

Done.
