PSXLinux (also known as Runix) is a Linux kernel and development kit for the PlayStation (MIPS-NOMMU). PSXLinux is based on the μClinux 2.4.x kernel and contains specific support for the Sony PlayStation.

Features[edit]

Compiling the kernel[edit]

Various attempts to compile the kernel resulted into either errors or people unable to run the kernel from suggested bootmethods. A Cross_compiler is required to make the kernel compatible for the Playstations CPU. [2]

Execution methods[edit]

Over SIO (Serial)[edit]

Loading the compiled RUNIX binary (PS-EXE) into a PlayStation may be done by using a Serial Adapter (such as the Net Yaroze Serial Cable) or Parallel Port device (Xplorer, Caetla). Another method is by installing a modchip within the PlayStation and burning a CD-ROM containing the executable data that will allow the system to boot burned discs. Runix did however supplied some tools on their website to transfer files if one had obtained or build their own serial cable, the filename was: psx-serial.0.9.7.tar.gz

From CD[edit]

Due to Linux ELF format not supported by the Playstation, conversion is required and a suggested path is to first convert the Linux kernel file to ECOFF, the NetYaroze native executable standard. This can be done with an enclosed tool called elf2ecoff inside the kernelsource. Next step would be to conver the ECOFF file to PS-EXE file, the format found on PlayStation game disks, after CDrom mastering a valid diskimage.[3]

Multiple Memorycards as Storage[edit]

From Beta1 on the Runix sources[4] support Multiple or single memorycards of the Playstations default size or larger. Multiple memorycards could have been formatted using a tool Runix supplied on their website to format into Ext2. The tools to do so seem to be lost or no sources can be found only the name: psx-mcard.0.8.2.tar.gz
