ide.multi-limit — IDE multiple sector read limit
If set, the value is used to limit the number of sectors read from an IDE drive in a single operation. With most drives this can be left unset. Some drives have firmware which incorrectly report the number of sectors they can transfer (Quantum Fireball TM series seem especially susceptible). This parameter allows the user to force ABLE to read a smaller number of sectors than the drives reported capability. The smaller of this parameter and the drives reported maximum number of sectors is used.
