Hello everyone,
My question is simple, I've got a USB Flash Drive with 128MB and I can run files from it when it's mounted in any OS. Well then being 128MB more than enough space is it possible to install a very stripped Linux on it with very general drivers so that I can always use most common pc's resources like keyb, mouse, screen, cdrom, floppy, internet, CPU, RAM, etc. ? and most importantantly is it bootable?
I was thinking of something like embebed Linux. When I'd boot the computer I'm on with it connected to the USB the Linux would then start, giving me a computer which to me is always the same independently of the machine I'm on. Wouldn't it be kewl!??

Welcome to LQ.org, delphinus!

I think you might be out of luck there, as many users can't even boot linux from a USB floppy drive - the BIOS often just doesn't support it.

If your final aim is to have an Linux distro independent from the host OS, try http://www.knoppix.net which is a distro on a CD, and runs directly from the CD.

As Q*Bert says booting from USB is dependent on the BIOS of the mother board. My Soyo KT133 can and I can even format my flash drive as a DOS bootable disk. But I haven't tried it out yet.

you can place kernel /boot partion on the floppy and the other file systems on the flash disk that can be option

The latest Knoppix release allows you to store your personal files / settings on a usb flash stick.

That's what they say on their website.

I'm downloading the iso right now, and will buy a usb flash stick in a few weeks.

I think this is the way to go, as Knoppix offers a lot of useful software along with good automatic hardware detection.
