All I can suggest is: In the file /boot/grub/menu.lst, edit the line: # kopt=root=/dev/hda1 ro to read: # kopt=root=/dev/hda1 dma=on ro of course make sure that "/dev/hda1" is correct for your setup. If you only have one HDD installed then it probably is already correct. Then run update-grub Install hdparm: aptitude install hdparm reboot then run: hdparm /dev/hda and see if dma is turned on, e.g: [EMAIL PROTECTED]:~# hdparm /dev/hda [..] using_dma = 1 (on) [..] If instead, it outputs "using_dma = 0 (off)" then I'm sorry, but I am unable to help further. You may want to run the hdparm command BEFORE you edit your menu.lst to ensure that the dma is actually off and you are not being deceived in some way. :-) -- Chris. ====== "One, with God, is always a majority, but many a martyr has been burned at the stake while the votes were being counted." -- Thomas B.
