I recently purchased a laptop that didn't have a option for a floppy. So I'v been looking for alternatives for emergency boot method via usb thumb drive or Generic CD.
I did find one site that goes into how to create your own bootable CD so I thought I'd pass it along, if someone was interested. Its at http://www.nu2.nu/bootcd/ and cover both linux and DOS bootable CD's.
Hope you find this useful or informative. Maybe the linux build post if they proceed?
