Hi folks, Finally Linux-2.4 kernel booted on PlayStation2 ! patch and binary is available at following URI: http://developer.hima.gr.jp/playstation2/patch-2.4.6ps2.0823.bz2 (bzipped patch for stock linux-2.4.6 kernel source) http://developer.hima.gr.jp/playstation2/vmlinux_246_0823.elf.bz2 (bzipped vmlinux. please uncompress before use) To compile the patched source, try following steps: $ cp arch/mips/defconfig-PlayStation2 .config; \ make ARCH=mips CROSS_COMPILE=/crossgcc_in_somewhere/bin/mipsEEel-linux- \ oldconfig dep clean vmlinux At present, you have to configure your network so that root file system can be mounted via NFS. 0. prepare NFS and BOOTP server on your network. 1. copy (whole) userland on PS2 Linuxkit to the NFS server and export them. 'no_root_squash' option is needed. 2. (optional) rebuild 2.2.1ps2 kernel with nfs-root and CONFIG_IP_PNP_BOOTP support, then test whether your nfs-root configuration works. 3. replace /nfsroot/rc.d/rc.sysinit with following shell script: --------------------- #!/bin/sh mount -n -t proc proc /proc &>/dev/null & mount -t nfs -n -o remount,rw 192.168.x.x:/nfsroot / &>/dev/null & mount -n -o rw,gid=5,mode=620 -t devpts devpts /dev/pts &>/dev/null & /etc/rc.d/rc7.d/S10network start &>/dev/null & /etc/rc.d/rc7.d/S50inet start &>/dev/null & /usr/sbin/inetd &>/dev/null & /bin/sh --------------------- 4. edit p2lboot.cnf on your memory card. my configuration is following: "vmlinux-246" vmlinux.elf "" 203 /dev/nfs "root=/dev/nfs nfsroot=192.168.1.1:/nfsroot,rw ip=::::::bootp" vmlinux-246 if you are using redboot.elf-010726, boot option given to redboot is passed thru to the kernel. 5. don't forget to remove or rename /nfsroot/dev/tst (*** THIS STEP IS IMPORTANT !!! *** ) 6. boot the (redboot then) kernel. you will see dmesg on the screen. you can check whether bootp and nfs-root are working. 7. (if you still wonder if things are working, use tcpdump etc.) 8. wow, it's show time! takahide@platinum:~/kernel/linux-2.4.6$ cp vmlinux /tftpboot;telnet dhcp1 9000 Trying 192.168.1.17...
