Image_menu cannot compile, complains about something double defined.... Just 
saw it, I will hunt for mknbi-menu instead :-)

which I steal code from. Thanks so far.

Is there a server for it?

I used the chance of the moment and changed the code to accept the following 
URIs:

"file:"  (0,1 or 3 times "/")  "disk/" (devicenumber, 0..3 allowed only)
to boot the MBR of a harddrive

append "/" (partitionnumber, 0..8 allowed, 0=MBR) to explicitely boot a 
partition.

"file:" (0,1 or 3 times "/") "floppy/" (devicenumber, 0..3 allowed only)
to boot a floppy device.

In plain language, you can enter into your dhcp "filename" parameter

file:disk/0
file:/disk/0/0
file:///disk/0/0

which would just boot MBR of first hard drive.

It is dependend from CAN_BOOT_DISK as the traditional "/dev/"... method, and 
it does nothing else then parse the line, so I meant not to make an 
additional compile-time option for it. It is not very likely that names like 
"file:vmlinuz" are used yet.

As I started implementing a tftp-mcast client (just for interest, and 
stealing most of the basic code from Eric's slam protocol) I would like to 
have the URI scheme "tftm:" (Trivial File Transfer protocol, Multicast mode) 
officially assigned.

While improving URI support, it would not be too much a hassle to implement 
the ability to have both TFTP and NFS at hand, so filenames beginning with 
one of the following should be treated "reserved" from now on:
(only the lowercase needs to be reserved for *n*x filenames, but written 
uppercase to increase readability):

FILE:
TFTP:
NFS:
X-SLAM: probably for the moment only
SLAM: probably in the near future, when it's no longer experimental
TFTM:
