RARP

If the CSMIM-T1 does not receive a successful BOOTP response, it uses
RARP to get the boot information. For a successful RARP retrieval,
TCP/IP must be running on a host that is on the same network as the
CSMIM-T1 and the host's ARP table must be initialized with the
CSMIM-T1's Internet and Ethernet addresses (see the arp man page,
arp -s).
The only boot information that RARP provides is the CSMIM-T1's
Internet address. The ROMs save this information in the inet_addr
parameter. The ROMs use default information for the Subnet Mask and
preferred load host. This means the ROMs will broadcast their request.
The host serving the CSMIM-T1 its boot information must be running on
the same network because the CSMIM-T1 only broadcasts BOOTP and
RARP queries.
If BOOTP and RARP fail, the CSMIM-T1 transmits an IPX
advertisement Request for Service and a MOP Multicast boot request.
If all requests fail, the CSMIM-T1 returns to the ROM monitor (if in test
mode) or continues the auto initializing procedure indefinitely (if in
normal mode).
2.8 SOFTWARE INSTALLATION PROCEDURES
Install the operational code on a UNIX host before loading it on a
CSMIM-T1. Please note that although the CSMIM-T1 will run on a
Novell system, it will not boot from Novell. The UNIX Installation Notes
describe how to install software on a UNIX host, as well as a non-UNIX
host. The CSMIM-T1 may also be booted from software loaded on
another CSMIM-T1 containing Flash, or from its own Flash memory (see
Section 2.7.2, Self Booting the CSMIM-T1).
When loading the CSMIM-T1 software for the first time, use the ROM
Monitor commands.
