I am a neophyte to Linux who recently successfully did a hard drive install of Knoppix 3.4 on my old computer after wiping off all evidence of Windows. Now I am trying to optimize my hard drives. As root, I can successfully execute commands like “hdparm –X66 –d1 –u1 –m16 –c3 /dev/hda”, but of course they are gone when I reboot. I have tried appending that line to /etc/init.d/bootmisc.sh" and rebooting, but this was unsuccessful in that the hard drive settings were still unchanged.

This all may be related to the fact that I had to initially install Knoppix using the cheatcode “nodma” because my CD ROM doesn’t support DMA. So now as it boots up I get a message something like “Skipping DMA acceleration as requested by command boot line.” Any suggestions on how to proceed to get my hard drives automatically optimized will be greatly appreciated. Thank you.
