Looks awfully fancy to me ;> Usually somethin as simple as
-c1 (to enable 32 bit) and -d1 (to enable DMA) is the optimum.
See 'info hadparm' for the whole story, including which options it
can be dangerous to fool with. Also 'hdparm -i' will give you many
clues as to the maximum settings for that particular HDD. BUT, every
version of Mandrake 8.x I've installed has automagically optimized my
HDD's. No need to run hdparm or put the settings in rc.local anymore.
BTW, any udma mode would be better than pio4 if the drive is dma
capable. hdparm -i will tell you that too.
