In your tutorial OSDev5.html, about half way down, when describing the two bpb values 'bpbReservedSectors and bpbNumberOfFATs', you make the comment
Through expermenting with reading images from formatted floppies and foppies with data on, I cant find a situation where the 2nd FAT starts in sector 3. What I have found is this:bpbNumberOfFATs rpresents the number of File Allocation Tables (FATs) on the disk. The FAT12 File System always has 2, 1 in the second sector, and 1 in the third sector of the disk.
Sector 1 - Bootsector with bpb.
Sectors 2 - 10 FAT 1 (assuming no hidden sectors)
Sectors 11-19 FAT 2
Sectors 19+ Root Dir.
I am just wondering if this is me doing something stupid or not as I am very new to writing bootloaders and operating systems.
As for the rest of the tutorial set - its brilliant. All I have ever been able to find online before are tutorials saying "if your new, DONT try writing a bootloader" or "Here is a hello world bootloader that does nothing".
10 out of 10!
