There are a couple of patches around that enable USB booting. Basically a delay (maybe 3-5 seconds sometimes) is needed in kernel init to allow the USB devices (hub, storage, etc.) to power up and be initialized and discovered. Search the linux-usb-devel mailing list for something like "usb boot" or "root fs on usb". One such patch is by Eric Lammerts, last posted on 2002-june-03, for 2.4.14. Aha, he has it here: http://www.lammerts.org/software/kernelpatches/usb-storage-root.patch Another one is at http://marc.theaimsgroup.com/?l=linux-usb-users&m=100408963708374&w=2 Both of these are possibly of out date by now, so need to be refreshed for current kernels. | > When I boot my floppy, I see the USB Storage | > driver printk, however, the kernel panics (cant find root /dev/sda1).
