Hi, following is done on HP DL320/G5p 

1. Have USB bootimage written to USB memory stick.
     1998585856 Dec  2 22:03 dfly-x86_64-3.6.0_REL.img
2. (screen) Boot from it, and then
   Select boot console by 9
   OK set boot_serial
   OK boot
3. (screen) Login as root and edit /etc/ttys
   (delete the first line and copy ttyv0 line, and
     change the word ttyv0 to console; kill -1 1;)
4. Login from serial as root:
5. Type ifconfig bge0
   Then I have attached log:

(It says parity error, but the machine is OK with memory test
and boot fine for other OSen.)

Thanks again,
