VGA Controller
The 2D VGA graphics controller console port is provided on a DB15F connector. Also,
Serial Flash memory with VGA BIOS and a 16MB video buffer (DDR SDRAM) is
included with the VGA controller.
PCI Interface
The PCI interface connects the PCI bus with the Management processor. This interface
emulates three 16550-style UARTs and part of the Management processor. Note that
this interface is equivalent to the HP developed DIVA ASIC.
I2C Bus
The I2C bus of the Management processor provides communication with the system’s
Baseboard Management Controller.
Console/Modem Serial Ports
The Management card serial ports can be configured to redirect system console and
session communications to the Management card’s RS-232 lines (local port) and a
modem (remote port).
Service LAN
Network access is provided by a 10/100BT LAN connection on a RJ-45 connector and its
associated LEDs, which are located on the Management card. An I2C 8K serial
EEPROM supports MAC address storage.
Disabling the X Server (HP-UX only)
If the X Server attempts to start up and no mouse is present it will detect this and
terminate. In the normal case the Common Desktop Environment (CDE) will notice that
X Windows has terminated and attempt to start X Windows again. This will continue
until either X Windows starts successfully or the system’s configuration is modified
using one of these procedures:
• CDE is disabled
• CDE is configured to run without starting X Windows
• X Windows is configured to run without a mouse
• A mouse is added to the system.
Here are the four procedures mentioned above and the steps required to accomplish
them.
Procedure One (HP-UX only):
Disable CDE by executing these steps:
1. Stop CDE by executing this command at the shell prompt as root:
#init 2
2. Disable CDE from running by executing this command at the shell prompt as root:
#/usr/dt/bin/dtconfig -d
