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.

7.Reboot the server blade with these new settings.
