Thank you for posting the entire readme fil for the flash prom updating
procedure. This way people will not only know where I got the the
firmware update file but also see the official procedure, described in
steps 4 and 5, prescribes copying the flash upgrade file to the local
hard drive and then booting from the disk using the file as boot image.
Perhaps someone will be able to then answer my question which is whether
this flash upgrade file, as it is being used as boot image, would work
if it is used as network boot image (rarpd/tftpd).
