Depends on the chipset. If you are talking BX, all modern Windows versions have the drivers included. If you are talking 815, only Win ME has them. If you have Win9x, NT, 2000, you have to put in the 815 inf files. You only need to put in the onboard video drivers if you use it. The Intel ATA100 drivers should be avoided. The Microsoft IDE drivers work better than the Intel ATA100 drivers.
