as best as I can remember, that's what I did ... tftp in the kernel and ... then have it look for the rootfs on the flash drive ... I remember that I had to add some sort of wait period so it had time to find the partition, files, etc of the rootfs on the pen drive...
If I remember correctly when I did this on the LSPro, I changed nothing in flash ... it was just tftp-ing the kernel and then telling it look for the rootfs on the flash drive...
