Why do you want that? Copying > even a moderately sized file would take you on the order of minutes. I still disagree. >From the help of CONFIG_BLK_DEV_AMD74XX: This driver adds explicit support for AMD-7xx and AMD-8111 chips and also for the nVidia nForce chip. This allows the kernel to change PIO, DMA and UDMA speeds and to configure the chip to optimum performance. I don't have nor an AMD, neither an nForce chip in that notebook. It doesn't look like a generic driver either. So why would I want it? >From lspci: 0000:00:1f.1 IDE interface: Intel Corp. 82801DBM (ICH4) Ultra ATA Storage controller (rev03) So ISTM if I want DMA (and I do), I only need one driver: piix. Please provide more information. Why do you think it's amd74xx the driver that I need, since I state (and I did in my previous message too) that I have an Intel chip? > As for the other drivers, if you don't tell us which they are, it is > difficult to provide an explanation.
