Dammed PCI mode on AGP card

[RoboPigeon]

Hi all, for a while ive been having problems with my motherboard (Jetway 663as, Via KT133) as no matter what graphics card i use (hercules Geforce 2mx or Hightech Excaliber 9600pro) it is set to pci mode and no matter what i do in the settings and bios settings nothing works to put it to AGP, i know there is a similar problem listed in the bios upgrades at the website but the latest version doesnt work for some reason and there customer services seems non existant. Any help would be great and thanks in advance.

have you tried clearing the bios and then setting it?
