Hi, Thanks for all of your previous help. But I meet another problem. ;( I tried to use l4linux with l4ide which needs omega0. Then, I found "con" would fail to load l4linux if omega0 was running. How can this problem be solved? Best regards! Jianjun Shen ___________________________________________________________ 雅虎邮箱超强增值服务－2G超大空间、pop3收信、无限量邮件提醒 http://cn.mail.yahoo.com
