Welcome to POSys official site!


POSys is made from 3 parts: the most important part is the KERNEL32 witch manages all processor related functions like memory access, tasks and I/O. Other functions like drive, video, keyboard and other device access are made only through drivers. Also file execution will be made through drivers. The only part of the kernel32 that can be modified is init32 that loads the first drivers and the user interface. 

        Check List:

 


The boot loader is the first executable part of the OS. This boot loader is made only for floppy disk loading.


Posys loader is the real-mode of the OS. It continues the execution as the boot-loader can't have more than 512 bytes. This part loads the kernel32 and does the CPU setup before changing to protected mode.
