This is what you need to boot from your USB flash drive (thumb drive isn't very good terminology). Build into your kernel the folloing: USB drivers for EHCI, OHCI, UHCI. Use only what your platform uses. (usb drivers section). Include the USB mass storage driver in the kernel. (usb drivers section) Make sure scsi disk block device driver is built in the kernel (scsi device drivers area.) Make sure filesystem driver is in the kernel as well. And as Chris stated, include rootdelay kernel parameter at the kernel line in your boot loader.

You're booting from a USB device, so the obvious answer would be the USB drivers. Are they built in, or modules? In particular, the usb-storage module, without which the kernel certainly isn't going to find a USB storage device...

You don't need to set anything in the kernel - it just takes some time for it all to be loaded from USB, so you only need a delay. Add rootdelay=10 to the kernel line in your bootloader config (feel free to adjust the number, could try lower if you want to see if it will work with less delay, or higher if needed). -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
