- Boot Console Handler (BCH)
This is the early boot console available during boot up on most PA-RISC machines,
provided by the Processor-Dependent Code (PDC).
See Also: BOOT_ADMIN.
- BOOT_ADMIN
This a command line utility stored in the boot ROM of
the PA box, which is used to configure the computer during early boot
sequence. It is a part of the PA-RISC machine's firmware.
See Also: Boot Console Handler (BCH).
- Guardian Service Processor (GSP)
The GSP is a console subsystem present
on certain PA-RISC systems, which provides several features such as remote
console, UPS management, system low level control.
- High Priority Machine Check (HPMC)
Fatal system error. Processor-Dependent Code (PDC) saves machine state in the
Processor Internal Memory (PIM).
- Hewlett Packard Precision Architecture (HP-PA)
'HP-PA' (sometimes 'hppa') is the short
way to refer to HP PA-RISC architecture. It's real meaning
is: 'Hewlett Packard Precision Architecture'. It
is used for instance by Debian
and OpenBSD to point out
their ports.
- Initial Program Loader (IPL)
It is the HP standardized system bootstrap responsible for
loading the operating system's kernel on PA-RISC systems. It can be launched
from the BOOT_ADMIN.
See Also: BOOT_ADMIN.
- Initial System Loader (ISL)
ISL is the executable that brings you into BOOT_ADMIN.
See Also: Initial Program Loader (IPL).
- Logical Interchange Format (LIF)
This is a HP mass-storage format used for exchanging files
among HP computer systems. It basically contains a header (identifying it
as a LIF volume) and a directory of fixed size containing the files. The
size of the directory is fixed when the volume is created, which explains
many things about the way PALO works!
- lifimage
It is the name contraction of LIF image, which is
indeed a file which format respects the LIF standard.
It can be seen as the equivalent of an ISO file,
having the LIF format instead of ISO9660.
See Also: Logical Interchange Format (LIF).
- Low Priority Machine Check (LPMC)
Generally a recoverable system error.
See Also: High Priority Machine Check (HPMC).
- Management Processor (MP)
The MP is a newer evolution of the GSP.
See Also: Guardian Service Processor (GSP).
- PA-RISC
PA stands for Precision Architecture. It is the name of two
generations of HP processors. They are classified as PA-RISC 1.X and PA-RISC 2.0.
But a system based on a PA-RISC processor is commonly called a HP-PA box.
See Also: Hewlett Packard Precision Architecture (HP-PA).
- PA LOader (PALO)
PALO is the PA/Linux kernel LOader. It was
designed by Paul Bame as a LILO equivalent for the PA-RISC
architecture.
- Processor-Dependent Code (PDC)
It is the firmware that handles all processor-dependent
functionalities, including hardware initialization and self-test procedures.
Once it has done this, it passes control to the ISL.
See Also: Initial System Loader (ISL).
- Processor Internal Memory (PIM)
Machine state is saved here after High Priority Machine Check (HPMC),
Low Priority Machine Check (LPMC), and Transfer Of Control (TOC).
See PDC_PIM in "PDC Procedures" chapter of PA-RISC I/O ACD
(available from
http://www.parisc-linux.org/documentation/.
See Also: Initial System Loader (ISL).
- netinst
This is not a PA-RISC specific term, though it needs
explanations. Network Install, also known as
netinst, are small ISOs containing everything you
need to boot a computer and install it from network. They are based on
the Debian distribution.
- SuckyIO
(added by special request) National
Semiconductor PC87560UBD, aka SuperIO.
Provides IDE, USB 1.1, Floppy Disk Controller, parallel port, 2 serial
ports, UIR (Infrared), etc. But since National denies the existence of
this chip and HP was the only client for this buggy PoS,
the name SuckyIO has stuck.
- SuperIO
Official term for SuckyIO.
See Also: SuckyIO.
- Standard Text Interface (STI)
It defines a standardized way to access the graphic subsystem
on HP-PA.
- Standard Text Interface Console layer (STIcon)
It is the basic text-mode console that can run on top of any STI-capable device.
See Also: Standard Text Interface (STI).
- Standard Text Interface FrameBuffer layer (STIfb)
It is a superset of STI, providing standard API to access framebuffer
devices on HP-PA.
See Also: Standard Text Interface (STI).
- Transfer Of Control (TOC)
This acronym can usually be found on some PA-RISC boxes, right near a tiny
switch that is not often used (hopefully).
On HP/UX it would make a crash dump and reset the box. It
can also be requested from the Guardian Service Processor (GSP). On Linux,
it will save the registers and reset, saved registers will be accessible
in the Processor-Dependent Code (PDC).
