Operating System PCF

x86 - 32 bits

Development Environment

OS:

• Windows 7 SP1 32 bits.

SDK:

• DJGPP Version 2.03;
• Microsoft Visual Basic Run Time v.5;
• mcopy and mmd;
• Custom build app (not in this repo, comment line 34 of SYSTEM_PATH\Makefile to compile);
• Cygwin (with package libintl3).

Testing:

• Bochs 2.3.7.

Others:

• Doxygen 1.5.6.

Quick Start

• Set ROOT_PATH var;
• Set TOOLS_PATH var (e.g.: TOOLS_PATH=%ROOT_PATH%\tools\bin);
• Set SOURCE_PATH var (e.g.: SOURCE_PATH=%ROOT_PATH%\OSPCF-Source);
• Set RELEASE_PATH var (e.g.: RELEASE_PATH=%ROOT_PATH%\release);
• Set SYSTEM_PATH var (e.g.: SYSTEM_PATH=%SOURCE_PATH%\system);
• Set DRIVERS_PATH var (e.g.: DRIVERS_PATH=%SYSTEM_PATH%\drivers);
• Set SYSTEM_OUT var (e.g.: SYSTEM_OUT=%SYSTEM_PATH%\bin);
• Set LIB_PATH var (e.g.: LIB_PATH=%SOURCE_PATH%\lib);
• Set APP_PATH var (e.g.: APP_PATH=%SOURCE_PATH%\app);
• Set INCLUDE_PATH var (e.g.: INCLUDE_PATH=%SOURCE_PATH%\include).

To Compile

After setting correct PATHS go to SOURCE_PATH and type make all. Kernel binary will be in SYSTEM_OUT.

To Run

GRUB is needed to correctly boot the system (version 0.95 is the only one i used for testing). To test in bochs make a floppy image (or .iso image) using mcopy and mmd. Kernel binary path must be in \kernel path and applications must be in \bin path. 32MB of RAM is enough to run the system. Kernel prints debug information through COM1 (only if parameter debug0=true is passed by GRUB in kernel loading).
