Hello. I'm trying to create a bootsector and it all went well until I saw that the sector number i wanted to load from disk was greater than 63 (using int 0x13, ah 2).

It seems like i need to convert LBA to CHS. I can't really find an answer to what "LBA" is.

Is it sectors or something more complicated?
