Check "man hdparm" for information on persistence of hdparm settings. I believe you can set it up so that these are persistent over a soft reboot. I can't recall the active flags off the top of my head, and don't have a Linux box handy, but do look up the -t and -T flags to hdparm - I have a vague recollection that they are what you are looking for.

Cheers,

I am not sure about this one though you may try out....

"hda=nodma" at the LILO boot prompt after "linux" or whatever label that you have choosen.

e.g, LILO: linux hda=nodma

if this works then you can add the following line to /etc/lilo.conf

append="hda=nodma"

.....and rerun `lilo'.

*Yes* Disabling DMA affects Disk read/write performance.

*BEWARE* I am only hypothesizing!! (oooops) Please read the kernel documentation. I am currently running kernel 2.2.14 (yeah, I know, has a bug). I don't have the kernel-docs on my system right now. You could get more (definitive) info under /usr/src/linux/Documentaion/* _______________________________________________ Richard Stallman's Public Lecture 5pm 17th July, at TIFR.
