In the BIOS setup, console redirect defaults to com2 port which explains why output stops after the loader passes control to the kernel. BTW, ipmitool always gives me "Info: cannot activate SOL payload with encryption" but ipmi-console (sysutils/freeipmi) works. If I change the console redirect to com1, my screen stays blank. Would you perhaps know how to use com1 for redirect and connect to it using ipmi-console (or ipmi-tool)? Thanks, Paul Schenkeveld
