VladFrost,do you mean PCI to ISA Bridge,that`s what it ask for on mine,anyway let Windows do the recommened search option,when I pointed to the folder where I had the Via 4 in 1(4.28) drivers it could not find them,so when I rebooted got new hardware detected & asking for the PCI to ISA bridge driver,anyway I let Windows find them & it found them in the same place "weird" & installed it.
You could try Nvidia drivers 6.50 drivers they seem fine to me,don`t forget to uninstall your old Hercules drivers first.
