Free Pascal Operating System
version 01-01-2010
Bugs and help / improvements will be appreciated, please send them to
(Yacine REZGUI) yacine.rezgui@gmail.com and
(Mario Ray Mahardhika) leledumbo_cool@yahoo.co.id.
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 )
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:
-
Next:
- System calls
- Multitasking
- Filesystem ( perhaps FAT12 is the most obvious, or should we create one ourselves? )
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 "run on (Qemu | Bochs).bat" to your Qemu / Bochs installation
* : on Linux, you must change 'i386-linux-ld' in make.rules to 'ld'
**: Windows only, most Linux users should get them easily
