Hi, All I can say is you aren't alone, I recently did eight tftpboot.img installs on some Sparc5,10,&20's, but I have four Sparc2's exhibiting the same problem you describe, can't even break with stop-A... Same server, same image, same switch between them... I recall a post recently about an IPC doing this too. If anyone can shed some light on this it'd be great. -Jon
