Max, thank you for the link, I have read
IRIX "Diskless Workstation Administration Guide".

I'm still a bit confused about "osloadfilename" and
"osloader" PROM variables. 

What I did was:

1. download O2 specific kernel file 
http://ftp.netbsd.org/pub/NetBSD/NetBSD-5.0.2/sgimips/binary/kernel/netbsd-INSTALL32_IP3x.gz

2. gunzip it and move to /tftpboot/netbsd-sgimips on the server

3. configure bootp and tftp on the server.

4. configure PROM variables as

> printenv
AutoLoad=Yes
diskless=0
dbaud=9600
volume=80
sgilogo=y
monitor=h
TimeZone=PST8PDT
crt_option=1
ConsoleOut=video()
ConsoleIn=keyboard()
cpufreq=180
eaddr=08:00:69:0c:0e:3f
OSLoadPartition=pci(0)scsi(0)disk(1)rdisk(0)partition(0)
console=d
netaddr=192.168.232.45
verbose=on
osloader=netbsd-sgimips
SystemPartition=bootp():
bootfile=bootp():netbsd-sgimips
kernname=bootp():/netbsd-sgimips
dlserver=192.168.232.1

5. boot

> boot
Unable to execute bootp():/netbsd-sgimips:  invalid argument
Unable to load bootp():/netbsd-sgimips: invalid bootfile 
bootp():/netbsd-sgimips.

Running tcpdump on the server, I get something like this:

(o2 is the hostname of O2, and buzi is the hostname of the bootp server)

I probably made a stupid mistake somewhere..

many thanks for your help
