Hello . almost 2 and half years ago we tried to make a simple operating system for our system programming course using assembly. This Website and its tutorials were huge help for us . This is just a simple OS which only has FAT12 driver implemented .(The save function never got told in the tutorial ...

Hello, The FAT specification says that different disk utilities can use different EOC (End Of Clusterchain. ie, end-of-file) markers. While Microsoft uses 0x0fff for FAT12, it can be different. Because the BAD_CLUSTER marker is at 0x0ff7 for FAT12, its recommended to test between 0x0ff8 and 0x0fff ...

hello all , im trying to save a file in fat12 structure . the loading procedure is given in the tutorial but the saving procedure is not . i myself came up with some sort of algorithm which im not sure of its correctness yet . can you verify its integrity ? you know , i dont know exactly how to go a...

could it be that because 0xFF8-0xFFF equals 4088-4095 which exceeds the number of actual clusters usable in Fat12 structure ? i mean because starting from 0xFF8 means the cluster you are looking for doesn't exist , ( or you have passed the boundary which specifies the last usable cluster in FAT12) (...

hello all , as you see in FAT12 , it says 0xFF8 - 0xFFF are used to indicate the Last cluster in file, my question is , why do we have this range for specifying the end of file!!? and why cant we use those last addresses for our clusters ? we could easily use 0xFFF as the indicator (or vice versa), ...
