Has anybody installed xp on an ASUS A7V ( just an ASUS A7V, not an ASUS A7V 133 etc )with a Hercules Prophet 2 mx 64mb graphics card. If so could you please post a message how it was done

Or does anybody know if an ASUS A7V is XP compatable...latest bios revision 1009

Thanx JohnJohn


I have the asus a7v w/ latest bios flash you mentioned. runs well with XP. However, I do not know about the video card you mentioned.

I have A7V with Bios version 1009 and a Hercules Prophet 3D II MX .
I had poblems with the famous 4nv_disp (or endless loop) failure.
Hercules recommended update with latest Via 4 in 1 and reinstalling Hercules SW. This did not solve the problem. Thereafter I reduced the AGP speed from 4 to 2 on the motherboard Bios. Now I have a totally stable system!

Hercules recommends to ommit the ACPI mode (back to normal PC mode), than I could switch back to AGP 2 to AGP4 mode.
However, since I have a stable system I will not do it. :p

ASUS A7V Rel 1.02 Bios 1009

Just curred my nv4_disp problem when using AGP = 4 in Bios.

Have a look on site:

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.

EP, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS

Been running around Quora lately, luv it there!
