SoftDev2 automatically boots from __mbr partition in PS2 fat models with internal HDD.
Run SoftDev2Installer.elf from your USB pendrive to install SoftDev MBR program (MBR.XIN) on your HDD.
SoftDev2 should automatically boot from your HDD.
On boot SoftDev2 will launch OPL (hdd0:__sysconf/softdev2/OPNPS2LD.ELF) by default. In addition hot keys were added which will launch corresponding application if hot key is held during boot:
- CIRCLE button: uLaunchELF (hdd0:__sysconf/softdev2/ULE.ELF).
- TRIANGLE button: OSD ROM browser (rom0:OSDSYS), FreeHDBoot (hdd0:__system/osd/osdmain.elf) or HDD-OSD browser (hdd0:__system/osd/hosdsys.elf or hdd0:__system/osd100/hosdsys.elf) if any installed.
ps2-browser launch feature is based on the FreeMCBoot 1.8 source code for OSDSYS patching, so credits go to Neme & jimmikaelkael.
