I would like to use my opensuse 10.2 system on a MSI K8N Neo2 Platinum

without the hd running, i.e. I imagine copying the files needed for my
daily work at the beginning of a session to a ram disk and then working
from there. At the end of such a script the hd will be turned off. But
... I do not know how to accomplish this turning off. So for hints as
detailled as possible as to how to turn off the hd in a script I would
be very grateful.

Very easy, but unfortunately not suse related.

1. Download a knoppix CD or, if you prefer, one of it'xs many deriatives.

2. Boot it

3. at the boot prompt, insert:
"knoppix dma toram" and whatever additional parameters you will need or
like.

This will copy the entire knoppix CD into your RAM (Provided you have
about 1GB, I think).

After this the whole system is both
-lightning fast
and
-very quiet.
And surely you can still save all your configuration and work results to
your harddisk or, better, you save soundlessly to an usb stick.

Btw, if you like something as soundless, but much smaller and even
quicker, DSL (damnsmalllinux) does essentially the same (with "toram").
With DSL, you will achieve the same mode of quiet and/or diskless
operation from 128 MB of RAM onwards.

I use both of them regularly. Essentialy anytime when I am away from a
diskless Terminalserver Client but still in a mood to have a speedy
computer that operates quietly....

Kind regards
Eberhard
