[rescue] net install redux

[Arthur Wouk]

i screwed up the install of sol 10 on my ultra-2, whose cdrom is dead.
so i tried to re-install using net install, as per Mike F's instructions
as of a year ago, posted on the rescue list. [i am running the install from  a blade 100 called blade.]

I started using the following when update4 of sol 10 came out, avoiding burning cds.
it worked just fine at that time.

==================================================================

here is what i get:

blade> add_install_client -i 192.168.0.18  -e 8:0:20:79:84:ad ul2 sun4u
blade> making /tftpboot
svcprop: Pattern 'network/tftp/udp6:default/:properties/restarter/state' doesn't match any entities
enabling network/tftp/udp6 service
svcadm: Pattern 'network/tftp/udp6' doesn't match any instances
updating /etc/bootparams
copying boot file to /tftpboot/inetboot.SUN4U.Solaris_10-1

whenever i try to install on any machine,  'boot net -i install' fails with
 a failure to connect.

any clue as to what is wrong?

if not, anyone have  an ultra-2 with a good cd or dvd reader, or a good
cdrom or dvdrom which would work in my ultra2? the machine has 2gigs of ram
dual 400mh cpus 40gigs of disk, and is my best sun machine.
