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.
