implementing FAT12

redDot · Post by **redDot** » Sun Mar 09, 2008 1:08 pm

hello friends,
I have an initial kernel, with the description tables, paging and kmalloc implemented. I now wish to implement some basic file system so that i may be able to write and read from the storage location. I believe FAT12 is the easiest one to start with. Could u guys please suggest me how to go about it, and which file system should i start with.

Thanks

have u a floppy/HDD driver? if u haven't, i saw a thread with a tut.. I'll give u the link

if u has such a driver, search in the wiki(have already links) docs about fs's. well, for floppy, fat12 is good for begin. if u want to work on a HDD, i recommend, something like SFS

I guess I can also point you here as well, as it covers fat12 at the assembly level. You can use it for better understanding of how fat12 works.
