Booting Installation on SunBlade
I'm new to the Sun world, but comfortable on i386 and mostly comfortable
on Debian for that platform.
I just got a lab full of SunBlade 100s that I get to play with for a
month or two before they go into production for college students. So of
course you know I want to try Debian on one of them. So I went to the
Debian home page and followed the links to download a Debian
Installation CD and burned this image:
When I turn on the SunBlade, I press Stop-A to get to an OK> prompt. I
insert the CD and then type "boot cdrom". On reboot I get an error of
"Wrong Magic Number on CD label" (or something similar; sorry I don't
have the exact message at the moment).
I did some searching of the archives, and it seems that maybe booting
from floppies/CDs doesn't work on the Sunblades. I tried to follow the
tftpboot "howto" that Paul Heinlein wrote up
but when I typed "boot net" I just got a bunch of "RARP timed out" type
errors. My linux box was on a different subnet; I wonder if the tftp
protocol doesn't travel across or is blocked at our router?
So, two things:
1) Can anyone speak to whether that CD image mentioned above will or
will not work on a SunBlade 100? Or perhaps I'm missing some operand to
the "boot cdrom" statement, etc?
2) Can anyone help me out with the tftboot process? Here's what I did on
my Debian i386 box:
* apt-get install tftpd rarpd
* created /etc/ethers and put the SunBlade's MAC address and
desired IP address, as so:
(the MAC address is not correct; I don't have the
actual address in front of me at the moment) and
made sure the file was world readable
* created /tftboot and made sure it was world-readable
* copied into that directory the tftboot.img file from
(I couldn't find the older 2.3.6 image Paul mentioned in his
"howto"). Made sure it was "other" readable.
* created a symlink to that tptboot.img file within the
/tftpboot directory. I named it in upper case letters,
converting each octect of the address in /etc/ethers to hex;
the result was "96FCA768". I originally had "macs04.acu.edu"
in /etc/ethers instead of the IP, but when I came to this step
and realized that Paul said this number was the hex form of the
Sunblade's IP address, I figured the two files had to tie
together somehow, and that Paul was using reserved DHCP in his
situation. Of course, this might be where my problem is :-(
* ran "/etc/init.d/rarpd restart" and "etc/init.d/inetd restart"
* fired up the SunBlade, Stop-A, boot net, timeout errors
Thanks for any assistance!
