If a partition isn't marked as "LBA" (with the partition id) then the kernel will uses CHS, unless it's beyond cylinder 1024. This is because some TSRs like to hook int13 and expect DOS to use the old int13 CHS style calls. If you don't like the somewhat inefficient LBA->CHS (by the kernel) and then CHS->LBA translation (by the BIOS) you can set ForceLBA.
