Good day,
For my motherboard ASUS CUSL2 with chipset Intel 815 there are some special Intel drivers that I thought was really good for the PCI bus. But now I read on Infinite Vortex site/ Optimizing your Win9x PC for Audio:
""""11. Make sure "DMA" is checked for your hard disks. Winkey+Pause (Or right-click My Computer > Properties) > Device manager > Diskdrives > Properties. If you don't see the DMA checkbox, then you might have the (evil) Intel ATA drivers installed. It's been suggested to uninstall these drivers as they steal CPU, and then you'll see the DMA box again, too."""""
