Good day.
I've managed to set up working rarp and tftp servers on an x86 debian
laptop, and I see the headless U60 booting across the network via a
terminal server on ttyA, but eventually the boot process hangs. Here are
the last few lines of boot messages:
--

The boot server directory /var/lib/tftpboot contains:
boot.img
C0A89E64 --> boot.img
...which I obtained from
/debian/dists/squeeze/main/installer-sparc/current/images/netboot
Hello,
It's not a tftp trouble. Your U60 is able to find your boot image. You
say that you don't have any framebuffer and output you have posted shows
that kernel tries to switch to a framebuffer to attach tty0. Can you try
with a frambuffer ? If not, you have to be sure that your boot image
contains all modules required to support console on serial line. If I
have more time this afternoon, I shall check on my U60.

Thank you Joel,
In fact there is an Expert 3D graphics card in the machine, but I don't
have either a monitor or keyboard attached. I understand that in the
absence of a real console a Sparc will drop back to ttyA for
input/output?
Of course, if you don't have any keyboard, openprom switch to ttya by
default, but you can configure this line. And in your case, openprom
switch to serial line. But if you want to access to your OS, it has to
support this serial line. Solaris support it by default, but I'm not
sure that debian does. Thus, you can see all messages sent by kernel to
openprom until kernel switches to framebuffer. I have installed some
T1000 without any trouble, but hardware support differs. Maybe there is
an kernel option for your case.
If I remember, you should have a SunSU serial and builtin support in
boot kernel. If boot image does not contains support for console on
serial line, you have to write a bug report ;-)

JKB
