I'm pretty sure you CAN do it because I thought I read where knoppix for example runs from a CD but I want to know --

which small linux distros can run from an sd card or usb flash drive?

my goal?

I have a dozen old P3 motherboards (733mhz) and I hate to junk them -- would like to build some MP3 players if possible.

would like something lean and fast that would boot up and auto start the player (and do a random play).

just have one folder of songs -- don't need to fast forward etc -- just PLAY.

so hopefully I can set it up and then disconnect the keyboard and monitor?

any help GREATLY appreciated. thanks.
