Only as serial one ! And this serial console is on the 8-port serial multiplexer board, and I miss a driver for that (same for SCSI !) on the E55 (9000/856). So the only chance is the use of PDC console for the first step. And as my experience shows on a PC with 8-port serial board, it is not a problem to poll in 20-25ms cycles, which is enough for serial console operation and is not a performace problem....
