IBM Using iPod to boot Linux on PCs
Applejack writes "Looks like iPod fever has caught on to Big Blue. IBM has a yet unreleased iPod-based software for rescue, restore, and recovery of failed Windows PCs. I read this description of the software on Amit Singh's blog, whose group at IBM apparently created this stuff. If I understand this correctly (and I think I do), the iPod contains IBM's rescue software along with Linux. A crashed PC boots into Linux from the iPod, after which you get all kinds of rescue & restore functionality ... web browsing and all, even if the PC's drive is totally hosed. All this while the iPod keeps working normally as a music player as it would. The blog has pointers to further information, including a Windows Media demo of the thing. " Should be noted this is not iPod specific; USB devices will do.
If you're looking for a cheaper solution, check out the Ultimate Boot CD. It has tools to test memory, CPUs, hard disks, and so much more.
It's definitely something to keep handy and is much cheaper than an iPod.
