The Human Interface; Output Devices; Input Devices - HP 9000 Series 310 Service Information Manual

The Human Interface
Several devices may act as the "console", or primary human interface for the Boot ROM. These
devices permit input and output functions between the person and the computer system. Possible
console devices are:
Output Devices
Functional output devices are listed below.
• HP 98642 (4-port, multiplexed RS-2:32) card with the remote bit set (with a supported
HP terminal).
Supported HP terminals are defined as those terminals supported by HP on HP-UX for the
Series
~~OO
computers. See the section of this chapter describing Remote Human Interface
for Boot ROM requirements.
• HP 98626 card with the remote bit set (with a supported HP terminal).
• HP 98644 card with the remote bit set (with a supported HP terminal).
• Human Interface Card (98561-66530) or Processor board RS-232 controller (same as 98644
card) with the remote bit set (with a supported HP terminal).!
• A bit mapped video board at internal address 56000016. This includes the HP 98700 and
all of the processor boards with video circuits.
The Boot
RO~1
tries to talk to devices with a primary DIO ID of 25 and a secondary DIO
ID of 1, and it expects these devices to have ID /FONT ROM information.
• An HP 98.546 Compatibility Display Interface. This alpha/graphics video card set is
similar to the HP 98204B card. Note that the Boot ROM will turn off video to this card
set just before booting an OS. It is up to the operating system to restore video if this card
set is to be used.
• HP 98f>27 Color Card
Input Devices
Functional input devices are listed below.
• Remote HP 98642 card with supported HP terminal.
• Remote HP 98626 card with supported HP terminal.
• Remote HP 98644 card with supported HP terminal.
• Human Interface Card (98561-66530) or processor board RS-232 controller (same as 98644
card) with the remote bit set (with a supported HP terminal).!
• Processor board HP-HIL, keyboard, and HP-IB electronics.
• I/O slot HP-HIL or keyboard electronics. The only version of this hardware is the key-
board electronics in the HP 98700 Display Controller.

Only one output device at a time will be used as the console output device, however, the Boot ROM will initialize and clear
any bit-mapped video circuits on the processor board and on video cards in the accessory slots that it finds, even if that
video circuit is not chosen as the output to the console device.
