With one of these parameter, one can enjoy the __silence__ stolen by his/her beloved computer :( -y put IDE drive in standby mode -Y put IDE drive to sleep e.g. hdparm -Y /dev/hda (assume you have only one hard disk, and your linux is there) But... As soon as the kernel accesses the hard disk (bflush? kswapd? etc.), gone is the __silence__ :( So I tried this: apm -s & hdparm -Y /dev/hda & sometime it works, sometime not. I know that "software suspend" is on the way, but till denn, this might be easier to "fix". Idea: One can __FREEZE__ the kernel, put IDE drive to sleep and then __sus pend__ the system, just like "apm -s" does. If the system wakes up again, waits till IDE is waken up (or maybe le ts the kernel wakes it up), and just continue to work as normal, stealin g your __silence__ again. Requirement: APM must work ;). ACPI never tested before. Purpose: To have ONE BIG BUTTON(TM) that give you a break! and just like magic, on an instant your are back on work again! If you lose your power during this suspend, then may the penguin be with you ;) I would like to call this feature HOT SUSPEND(TM) :) Best regards, Soewono Effendi DISCLAIMER: I take no responsibilities in any case of data and/or hardware lost if you try these experiments :) ----------------- SEffendi(a)web.de ================= ______________________________________________________________________________ FreeMail in der Premiumversion!
