What exactly is this? What do us OS programmers need to do with it? It stands for Linear Block Address, right? What is the significance of this? Thanks!

An EIDE technique
Used by BIOS for int 13h, to access hard disk larger than 1024 cylinder

Dot not confuse with

Its now an old CHS (Cylinder Head Sector) conversion method, used to convert a physical CHS to a logical CHS adress
