ASUS A7V Rel 1.02 Bios 1009
Just curred my nv4_disp problem when using AGP = 4 in Bios.
Have a look on site:
http://www.a7vtroubleshooting.com/forum/cgi-bin/yabb/YaBB.pl?board=a7v
I had exactly the described fault situation. In Bios: advanced menue/chip configuration items:
AGP Drive Strength P Ctrl was not by default = "C" but "9" and
AGP Drive Strengh N Ctrl was not be default = "E" but "D"
setting it manual did not help, after rebooting the old D9 value was back again. The tool "pcredit"from
www.h-oda.com made this visable.
Follow the instrution on the a7vtroubleshooting site above.
When running the wpcredit program just look for the crosspoint
"B0" and "01" ( B0x01) Also in may case I found "D9" instead of " EC"
now Win XP / Asus 7V version 1009/ Hercules 3D Prophet II MX (with XP driver) is stable!
I also have latest Via 4 in 1. If it reall is needed I do not know.
I already had them installed before fixing the problem.
