HP BIOS Serial Console/EMS Support Settings and Configuration 19 Microsoft® enables EMS support in the OS, but EMS support also requires ROM support. EMS support, when enabled, assumes the serial port for redirection and may cause interference with other devices attached to the serial port. To avoid interference, EMS is disabled in the system ROM by default on ML and DL servers. To enable this feature, Enable Local or Enable Remote must be selected under the BIOS Serial Console/EMS Support menu in RBSU before installing Windows® Server 2003. If you install Windows® Server 2003 with EMS disabled, and later decide to enable it, perform the following steps to update the boot.ini file: 1. Enable EMS in RBSU. 2. Run bootcfg/ems on/id 1. 3. Reboot. Linux Red Hat 7 Serial Console Settings If you are using an HP ProLiant BL e-Class server, each server blade maintains a connection to COM 1, so they are primarily used remotely through the Integrated Administrator. To enable BIOS Serial Console for Linux Red Hat 7 OS: 1. Remove the line: message=/boot/message from /etc/lilo.conf 2. Add the following line to the Linux image specification in /ect/lilo.conf: Append="console=tty0 console=ttyS0, 115200" 3. Run /sbin/lilo to make the changes take effect. 4. Add the following line to the end of /etc/inittab to enable agetty on COM1 (ttyS0): 7:12345:respawn:/sbin/agetty 115200 ttyS0 vt100 5. Set SAFE=yes in the file /etc/sysconfig/kudzu, so it does not probe the serial port during initialization. 6. Add the following line to /etc/securetty to allow root to log in on the ttyS0: ttyS0 7. Reboot the server blade with these new settings.
