Tuka:
Thanks for your reply.
How can I get the useful hint from /var/admin/message file?
I had checked file system, but that did not work, so I had to reinstall the system from cdrom, but there was no response when the setup process get to the "Hostname Input", that happened whenever I use solaris 7 or 8!
The hardware type is double-sparc 450 CPU, double-512M RAM, One 36G hard-disk, Three 10/100M Network Cards, no other peripheral equipment.
I think there must be some hardware device problem,
all the problem appear when need to "input".
Can you give some advice?
