filename in BOOTP reply vs RFC 951

[Eduardo Fleury]

Hi, how are you?
I've set up an ISC DHCP/BOOTP server so that it provides a set of images I
need to make an IBM Power machine boot from the network, however I've run
into a situation that might require a correction in the dhcp server.

The issue is the following, the image I'm trying to boot is split in several
files due to a few design restrictions. In order to boot I's expecting the
following to work:

field).
2) SERVER sends bootp reply with default filename (as specified in
dhcpd.conf or whatever)
3) CLIENT gets the first file with TFTP.
4) CLIENT sends a bootp request for the 2nd file - filename field IS
SPECIFIED.
5) SERVER sends a bootp reply to let the client know it can get the SECOND
