Abstract

U ovom radu prikazano je ostvarenje upravljačkih programa za ATA kontroler i PCI sabirnicu te implementacije FAT32 datotečnog sustava i apstraknih slojeva blok uređaja i virtualnog datotečnog sustava. Rješenje omogućuje jednostavne operacije nad datotekama datotečnog sustava. Svi dijelovi rješenja su napisani u programskom jeziku C kao i sam operacijski sustav Benu. Ostvarenje je testirano jednim primjerom gdje je otvorena slika postojećeg datotečnog sustava, promijenjen je sadržaj dviju datoteka te je nakon toga datotečni sustav provjeren kroz datotečni sustav Linuxa.

Abstract (english)

The goal of this work was to implement the drivers for the ATA controller and the PCI bus but also to implement the FAT32 file system and two abstract layers for block devices and the virtual file system. The produced solution can perform simple operations on the files found on the file system. All code is written in the C programming language as is the operating system Benu which we are using. An example was demonstrated in which we opened a file, read it's content and written back the new content. After that the disk was mounted in Linux in order to verify that the solution worked properly.
