Kernelloader for PS2 Linux ########################## This program can load a Linux kernel and start it on the Sony Playstation 2. The program is working with the old fat PS2 and the new slim PSTwo. The support for the old fat PS2 is better. USB is unstable on the slim PSTwo since version v14. You need a method to start PS2 homebrew software. You can control the kernelloader software with the first game pad or a USB keyboard (UP, DOWN, CROSS or RETURN). To enter texts (e.g. kernel parameter) you need the USB keyboard. The easiest way for testing is using the PS2 Linux Live DVD at: http://sourceforge.net/projects/kernelloader/files/BlackRhino%20Linux%20Distribution/Live%20Linux%20DVD/ The Linux DVD doesn't work on v12/v13 PS2 consoles from some regions. Otherwise you will need a Linux kernel and a initrd for testing: http://sourceforge.net/projects/kernelloader/files/Linux%202.4/Linux%202.4.17%20Kernel/ http://sourceforge.net/projects/kernelloader/files/Initial%20RAM%20Disc/ You can copy the files to an USB stick and then select the files in the menu ("Select Kernel" -> vmlinux, "Select RAM disc" -> initrd). Virtual Keyboard ################ The input fields in kernelloader supports a virtual keyboard. The virtual keyboard is controlled by the game pad. This allows to enter kernel parameter with the game pad without an USB keyboard. The cursor is blinking. When it blinks it shows for a short time an underline sign and for the remaining time the character which will be inserted when pressing triangle. The default is the invisible space character. The buttons have the following functions: - The character is selected with R1 and L1. - The triangle button inserts the character. It can be inserted multiple times. - Left and right moves the cursor left and right. - The square button deletes the character which is left to the cursor. - The circle button is for fast jumping in the character selection. This is the same as pressing R1 for 16 times. You get from a capital letter to lower case by pressing circle 2 times. - The start button jumps to the beginning of the text. - The select button jumps to the end of the string. Video Mode ########## The application use the default video mode configured for your PS2. The default mode is PAL, NTSC or 480i when component output is selected instead of RGB/Composite. To use it with VGA monitor you need the VGA cable and a monitor which supports SOG (Sync On Green). When kernelloader is started, you can switch the video mode using the L2 and R2 buttons on the first pad. After a mode change, you should go to the file menu and restore defaults, because this will automatically set the kernel parameter accordingly. The "+" and "-" keys on the keyboard also switch the video mode when the focus is not in a input field. The following function keys switch the screen mode: F1: Auto detect F2: VGA 640x480 60Hz F3: VGA 640x480 72Hz F4: VGA 640x480 75Hz F5: VGA 640x480 85Hz F6: DTV 480P F7: NTSC F8: PAL Auto-Boot ######### To stop Auto-Boot you need to press a button on the first game pad or a key on the USB keyboard. Recommended Peripherial Hardware ################################ The following hardware is recommended: - USB keyboard (need to be supported by Linux 2.4.17) - USB mouse for use with the graphical user interface - PS2 memory card (original or a newer version from Datel which works without a boot CD) - PS2 game pad (USB keyboard and mouse also works) - HDD adapter for the old fat PS2. The adapter can be used to connect a parallel IDE hard disc and a network cable. The slim PSTwo has already a built-in network adapter. The HDD adapter can't be connected to the slim PSTwo. As far as I know there are HDD extensions available for the v12. Later slim PStwo consoles doesn't support these extensions. - USB memory stick to store the Linux kernel and the initrd files. It can be used instead of the hard disc to store the file system for Linux. Don't forget that USB is unstable on slim PSTwo v14 and higher. - A readable disc must be in the tray when starting kernelloader (The tray must be also closed). Otherwise there can be a freeze until a disc is inserted. If HDD adapter is not connected, kernelloader will not load the network modules, even if these are enabled. If you have a HDD adapter or a slim the network cable need to be connected before starting kernelloader and there must be a network link. How to Build a VGA cable ######################## You can build your VGA cable yourself without soldering. You need to buy the following products: - one PS2 or PS3 component cable (YPbPr) - one RGB cinch to VGA adaper (1 x female Sub-D 15 pol, 3 x cinch female or male with colours Red, Green and Blue) - If the 3 x cinch is male, you need a 3 x cinch adapter The colours of the RGB VGA adapter are the same on the PS2/PS3 component cable. Connect the cinch connectors as follows: Pr (red) to R (red) Y (green) to G (green) Pb (blue) to B (blue) DVD Video ######### The kernelloader and the newer Linux 2.4.17 supports reading of DVD video. This can be used to read burned DVDs. The module eromdrvloader.irx enables the support for this feature. The PS2 Linux Live DVD uses this feature to be able to run from a DVD without a modchip. To be able to use burned DVD, the DVD must be conform to the DVD video standard. This feature will not work on the first PS2. There are also problems on the slim PSTwo, especically v12. On the v12 the reading of the NVM fails. The region can't be detected and the wrong module may be loaded. If you report an error, please include the informations from the Versions menu of kernelloader. Configuration Order ################### At startup the default configuration is set. Then configuration is loaded from a file. When a value is missing in the configuration file the default configuration is used. The search order of the configuration files is "cdfs:config.txt" and then "mc0:kloader/config.txt". The auto boot time and the video mode is part of the configuration file. ROMGSCRT ######## The ROMGSCRT module is responsible for setting up the video mode. SBIOS ##### The SBIOS is the interface between the Emotion Engine (main processor) and the IOP (Input/Output processor). Linux runs directly on the Emotion Engine and uses SBIOS and ROMGSCRT. On the IOP modules from Sony are running (IRX). The Great Experiement (TGE) ########################### Kernelloader is based on TGE from Marcus R. Brown. The TGE includes the SBIOS and the modules intrelay.irx and dmarelay.irx. dmarelay.irx from TGE is not working. Run Time Environment (RTE) ########################## The RTE is stored on the first disc of the offical Sony Linux Kit. TGE (The Great Experiement) is normally used by kernelloader. Some stuff like sound and DMA is not fully working in TGE. You may need stuff from RTE to get full support. Sound Support ############# If your PS2 is an old fat PS2 (v7 or earlier, maybe also v8 or v9, but not the first PS2 without libsd), sound is automatically working. LIBSD 1.04 or lower is needed to get sound support. There is also the SDRDRV needed. The newer PS2 consoles include newer versions of LIBSD and SDRDRV. These versions don't work with the Linux sound driver. To get sound working you can get these files from RTE, an old game disc or from a BIOS dump of a old PS2. DMA Support ########### DMA is needed for faster transfer rates (Sound and IDE). To get DMA support you need the module dmarelay.irx from RTE. Linux 2.4.17 doesn't support this module, you need the old Linux 2.2 from Sony. Module Information ################## You can select which IOP modules are loaded in kernelloader. Module names prefixed with "rom0:X" are the new rom modules. Module names without the "X" are the old ones. Each playstation has the same version of the old modules. ps2link is only for debugging. It's purpose in this project is to print debug messages over network. The messages can be seen on the host using ps2client. The new modules can be different. Here is more information about the modules (the modules are listed in groups, only one module of a group is required): eedebug.irx Required: No Patch: patches/linux-2.4.17_ps2-iop-debug.patch Module send all output of IOP processor to host. Linux patch is required to see this information at "/proc/ps2iopdebug". init.irx imodule1.irx imodule2.irx imodule3.irx imodule4.irx imodule5.irx Required: No You can copy a module to mc0:kloader/ to add a custom module, you want to load. SIO2MAN XSIO2MAN sio2man.irx freesio2.irx Required: Yes System module. Required to start other modules. MCMAN XMCMAN mcman.irx Required: Yes, or accessing memroy cards. Access to PS2 memory cards on IOP. MCSERV XMCSERV mcserv.irx Required: Yes, or accessing memroy cards. RPC server for MCMAN. Linux will call the RPC server. PADMAN XPADMAN padman.irx freepad Required: Yes, for accessing playstation game controllers. Driver and RPC server to access gamecontrollers by EE. iomanX.irx Required: No, only for ps2link. File IO driver on IOP. poweroff.irx Required: No, only for ps2link. To get poweroff button working when hard disc is used (DEV9, ps2link). dev9init.irx Required: Yes, only for fat PS2. Incompatible with slim PSTwo. Configure dev9 (expansion bay, ethernet + hdd). ps2dev9.irx Required: Yes, for slim PSTwo and for ps2link. Driver for DEV9 (hardware interface to expansion bay or PCMCIA). Grants access to network and hard disc. ps2ip.irx Reuqired: No, only for ps2link. TCP/IP network stack on IOP processor. ps2smap.irx Required: No, only for ps2link. Network driver on IOP processor. Linux has it's own driver. When this driver is used and Linux driver is activated. Linux driver will deactivate this one. When IOP tries to use the network the system will hang. This module is incompatible with ps2smap.irx. smaprpc.irx Required: Yes, for slim PSTwo if you want to use ethernet. Network driver on IOP processor. You need also to load ps2dev9.irx. This module is incompatible with ps2smap.irx. ps2link.irx Required: No, only for ps2link. ps2link is a IOP module which helps debugging. sharedmem.irx Required: No, only for ps2link or if you applied the patch. Patch: patches/linux-2.4.17_ps2-printk.patch This module is only for debugging and is easier than the RPC interface. Its purpose is to get a easy way to print messages on EE. If you applied the patch Linux will only start if you load the module. iopintr.irx intrelay-direct.irx intrelay-direct-rpc.irx intrelay-dev9.irx intrelay-dev9-rpc.irx Required: Yes Redirects interrupts from IOP to EE. You need only one module. The normal module is "intrelay-direct.irx". If you use ps2link or ps2dev9 you need to load "intrelay-dev9.irx". The RTE module "iopintr.irx" doesn't include the USB initialisation. "intrelay-*.irx" modules include the USB initialisation, so it is recommended to use "intrelay-*.irx" instead of the RTE module. When you have a slim PSTwo you should use a module with "rpc" in the name and a Linux patch: patches/linux-2.4.17_ps2-rpc-irq.patch System can hang if you try to use network from IOP and EE! dmarelay.irx Required: No Redirects DMA from EE to IOP and backwards. There is no Linux driver using it correctly. Its purpose is to speed up network and hard disc. Only the RTE module is working. CDVDMAN XCDVDMAN cdvdman.irx Required: Yes Reading CDs and DVDs. CDVDFSV XCDVDFSV Required: No I believe it is not required by Linux. ADDDRV Required: Yes, for reading video DVDs. Enables access to rom1. eromdrvloader EROMDRV Required: Yes, for reading video DVDs. Need to be loaded to read video DVDs. LIBSD libsd.irx freesd.irx Required: Yes, for sound. Need to be loaded to get sound working. Only the RTE module is working. ROM1:/LIBSD from SCPH-77004 is working with sdrdrv.irx from RTE. SDRDRV sdrdrv.irx Required: Yes, for sound with original Sony Linux Kernel. Sound server. Only the RTE module and ROM1:/SDRDRV from SCPH-39004 is working. Modules from SCPH-50004 and higher are not working (SDR driver version 4.0.1 (C) SCEI). The RTE version is: SDR driver version 2.0.0 (C)SCEI The SCPH-39004 version is: sdr driver version 1.4.0 (C)SCEI audsrv.irx Required: Yes, for sound with special Linux Kernel. Sound server. ioptrap.irx Required: No, only for ps2link Module is only for debugging. RMMAN RMMAN2 Required: No Driver for remote control. This not supported in TGE and RTE SBIOS. Loading Custom Kernelloader Modules ################################### Kernelloader includes default modules. You can replace the modules by copying other versions to the directory "mc0:kloader/". The following modules are loaded for kernelloader. These modules are only used within kernelloader and not by Linux. Here is the list in loading order: SMSUTILS.irx SMSCDVD.irx ioptrap.irx iomanX.irx poweroff.irx ps2dev9.irx ps2ip.irx ps2smap.irx ps2link.irx usbd.irx usb_mass.irx fileXio.irx ps2kbd.irx When your USB memory stick is not supported within kernelloader, you can replace usbd.irx and usb_mass.irx. Just copy the files to "mc0:kloader/". It is possible that kernelloader will not start afterwards. To get it working again just remove the files or remove the memory card. Loading Custom Linux Modules ############################ Kernelloader includes default modules. You can replace the modules by copying other versions to the directory "mc0:kloader/". The following modules are loaded for Linux. These modules are only used by Linux. Here is the list in loading order: init.irx (*) sio2man.irx mcman.irx mcserv.irx padman.irx libsd.irx sdrdrv.irx iopintr.irx dmarelay.irx cdvdman.irx cdvdfsv.irx module1.irx (*) module2.irx (*) module3.irx (*) module4.irx (*) module5.irx (*) sbios.elf These modules need to be selected in the module configuration menu. These modules are automatially choosen if you submit with RTE modules enabled. There is a menu entry which copies the RTE modules from Sony's Linux kit DVD. sbios.elf is extracted from pbpx_955.09. Modules marked with (*) are not part of RTE and can be used to load custom modules. Extracting RTE modules and SBIOS ################################ At the end of the configuration menu there is a menu entry for copying RTE modules and SBIOS from Sony's Linux Kit DVD 1. There are menu entries for changing the source path if your DVD looks different. When the files doesn't exist, it is possible that it will hang. This problem is caused by the Video DVD driver. You need to copy/extract all files. Then you can select all RTE modules and RTE SBIOS in the module and configuration menu. You need also to disable CDVD SBIOS calls, because Linux will not start when the calls are enabled and RTE SBIOS is used. Don't use iopintr.irx from RTE, because USB will not work. The intrelay.irx from TGE is working better.
