Hi all,
Once again, I ask you to verify what I wrote and only God knows how
important it is to re-read this file b/c it is useful and I made it so
many mistakes for sure :)
I added the comments of the first draft (Thanks to Grant) and CPU type
help too. I do not really like the lists. If you have any better idea,
please let me know.
Thanks, Thomas.
ESIEE Team
PS: I would like to know if I can put the PA-RISC/Linux Boot HOWTO into
stable state??
Text to add in Documentation/ Configure.help
======================================================================================
Processor family
CONFIG_PA7100
In this section, you will find enough informations to set correctly
your CPU type option. Nevertheless, if you need more, you can see
all the hardware content of your box at http://hwdb.parisc-linux.org.
If you select the PA7000/PA7100 option, your box must be one of these
listed below: 705/35, 710/50, 715/33, 715/50, 715/75, 720/50, 725/50,
725/75, 730/66, 735/99, 735/125, 750/66, 755/99.
If you select the PA7200 option, your box must be one of these listed
below: C100, C110, D250, D350, D260, D360, J200, J210, K100, K200,
K210, K220, K400, K410, K420.
If you choose the PA7100LC/PA7300LC option then your box is 715/64,
715/80, 715/100, 725/100, A180, B132L(+), B160L(+), B180L(+), C160L,
C180L, D200, D210, D220, D230, D300, D310, D320 or D330. There are
also some systems from the E series but there are not yet supported.
Finally, PA8x00 is the good choice for all new stuff like A500, B1000,
B2000, B2600, C200+, C240+, C3000, C3600, J282, J2240, J5000, J6000,
J6700, J7000, K250, K260, K270, K370, K450, K460, K470, K570, L1000,
L2000, L3000, N4000, V2200, V2250, V2500.
Now, you should be sure of which CPU type. If not, please send a mail
to parisc-linux@lists.parisc-linux.org.
64-bit kernel
CONFIG_PARISC64
The 64-bit kernel support give the capability of using 64-bit CPU to
the kernel. This is useful for PA8X00 series minimum. Note that even
if your kernel is 64-bit, your userspace will be in 32-bit.
GSC/Gecko bus support
CONFIG_GSC
This option gives to the kernel the capability to manage GSC buses
of HP computers. More than that, if you have systems with GSC slots,
LASI, EISA or Dino (GSCtoPCI) bridge, this option is also compulsory
if you want it working.
LASI I/O support
CONFIG_GSC_LASI
LASI is one type of controller embedded in HP workstations and
servers. It controls some I/O devices like PS2 keyboard and mouse,
audio or serial interface. The best advice is to keep it in your
configuration, if you are not sure about that point.
WAX support
CONFIG_GSC_WAX
WAX is an EISA bus converter for PA-RISC systems. It can be found in
older systems like B/C/D/R-class machines. This option enables this
converter. Note that it is under heavy development. Thus, it may not
be working.
GSCtoPCI/DINO PCI support
CONFIG_GSC_DINO
By selecting this item, you add PCI support for Dino PCI Host Bus
bridge.
PCI devices are sometimes embedded in GSC add-on cards (aka "card-mode
Dino"). Note that only recent systems need it like B132L, C200. For
more
information, go to http://hwdb.parisc-linux.org.
Chassis LCD and LED support
CONFIG_CHASSIS_LCD_LED
HP boxes have LED or LCD indicator on the front in order to show some
basic information like status for example. With this enabled, you can
have this help also available.
Kernel support for SOM binaries
CONFIG_BINFMT_SOM
SOM (Spectrum Object Model) is a format for libraries and executables
used by HP. Saying Y here will enable your kernel to run SOM binaries.
As a result, you could run HP-UX executables. This capability is still
in development. Then, you use this functionality with no warranty!
LASI/ASP builtin parallel-port
CONFIG_PARPORT_GSC
If you have a LASI or ASP controller in your HP box and you want to
use
the parallel port, a good idea will be to keep this item in your
configuration.
HP Lasi SCSI support
CONFIG_SCSI_LASI
If you have an old HP system like a 712, you should keep this on.
This will enable your SCSI controller and give you access to
SCSI devices. For quite recent computers, you may be able to turn
this off.
Lasi ethernet
CONFIG_LASI_82596
This option adds the driver for one of most used network chips
integrated in LASI chip. It is also known as Apricot driver. It is
based on an Intel 82596 chip. If you do not know what is your
hardware, it is strongly recommended to keep is on.
Support for Lasi/Dino PS2 port
CONFIG_GSC_PS2
The PS2 connector of the HP boxes looks like a standard PC connector.
If you want to use the PS2 keyboard and mouse, you must keep this on.
Anyway, some HP workstations and servers have this kind of interfaces
but not the ports you can plug in your devices. Thus, the best thing
to do anyway is to let this choice turned on.
serial port on GSC support
CONFIG_SERIAL_GSC
For most of the HP servers and for some workstations that do not have
its video card supported yet, you will need to get the console output
via the serial port. As a result, you could interact with the box via
a VT or a serial cable link to another computer.
STI console
CONFIG_STI_CONSOLE
The Standard Text Interface could correspond to the VGA support for
PC.
HP developped STI as a mechanism between CPU and graphics devices.
Thus, if you want your console on your screen like any other PC linux
does, leave this option on.
If you do not have any success with your console output, we advice you
to check if you have checked the STI frame buffer option, aka
CONFIG_FB_STI, in your configuration. Some models are happy when the
two of them are enabled and some others prefer to have only this one
only.
Anyway, if you failed to have the screen output, you can switch to the
serial console output.
PA Harmony audio driver
CONFIG_SOUND_HARMONY
This option enables the audio part of the LASI controller. Since it is
standard to all the boxes, this option should be set for any
workstation except the newest ones. Servers do not really need audio.
Then, you can unset it.
