CHS requires a few 24 bit divisions to calculate CylinderHeadSector
number out of the sectornumber. That makes it a little more slow, than
modern hd's which support LBA mode.(sectornumber is passed directly to
hd) And of course modern harddisks are faster because they are made with
newer technology.
Other soundrelated issues: IDE bios leaves interrupt unchanged when
accessing harddisks, but when ATAPI devices are accessed (CDROM, ZIP,
...) IDE bios sets DI.
