FPOS - Free Pascal Operating System
Project started in 01-01-2010 and coded with
Introduction :
| Boot | Shell (CLI) | Command (Help) |
|---|---|---|
 |
 |
 |
✔️ Implemented :
- GDT, IDT ( no problem... I hope )
- ISR ( currently, only page fault has additional handler )
- IRQ ( no problem... I hope )
- Console ( including simple command processing )
- Keyboard ( try to be US-std, but I don't know the keymap. Just guessing for now )
- Memory Manager ( needs testing )
- Speaker ( just for fun :-) )
- RTC ( seems wrong at PM, also for DayOfWeek )
- System calls
- Multitasking
- Filesystem ( perhaps FAT12 is the most obvious, or should we create one ourselves? )
🔧 Fixed :
- Successive Write(Ln) fails due to 103 IOResult
- Some inline assembler and assembler routines are missing register list, causing it to crash randomly (please test)
📋 Changed :
- Updated to FPC RTL revision 14499
➕ Added :
- Not
📅 planned for now
📝 Note :
- Some files are not used due to unusability ( multitasking & filesystem )
⚙️ How to compile :
- Make sure you have working FPC installation ( try using latest 2.5.x snapshot if your version fails )
- Copy executables** under tools to a directory listed in your PATH ( or Path )
- Open Command Prompt ( start->run->cmd ), cd to fpos top directory, then type 'make'
⚗️ How to test :
- Adapt (Qemu or Bochs).bat to your Qemu / Bochs installation
- On Linux, you must change 'i386-linux-ld' in make.rules to 'ld'
