Re: Intel Turbo Memory, aka Robson

Simple, I think the best thing to do is to put the swap partition on this.

It solves the problem with the restore from hibernation speed. It also
speeds the use of swap.

I won't make any comment on the strutural intelligence of this 'feature'...

There is complete silence on LKML and everywhere apparently about how
to use the Flash drive known as Turbo Memory in Linux.

This stuff is a flash connected to the PCI bus which Vista seems ale
to use to store frequently accessed data, so it bypasses the hard
disk, thus saving time. It's present on modern laptops, and is coming
to the desktop too.

I was wondering if anybody and better info than I, as I would be
interested in using it to save hibernation images and such, to speed
up restore time...

Nothing in the logs though...
