For most of today's controllers, MaxDevices will either be 1 or 2. For SATA \r
controllers, this value will always be 1. SATA configurations can contain SATA \r
port multipliers. SATA port multipliers behave like SATA bridges and can support\r
- up to 16 devices on the other side. If an SATA port out of the IDE controller \r
+ up to 16 devices on the other side. If a SATA port out of the IDE controller \r
is connected to a port multiplier, MaxDevices will be set to the number of SATA \r
devices that the port multiplier supports. Because today's port multipliers \r
- support up to 15 SATA devices, this number can be as large as 15. The IDE bus \r
- driver is required to scan for the presence of port multipliers behind an SATA \r
+ support up to fifteen SATA devices, this number can be as large as fifteen. The IDE \r
+ bus driver is required to scan for the presence of port multipliers behind an SATA \r
controller and enumerate up to MaxDevices number of devices behind the port \r
multiplier. \r
\r
In this context, the devices behind a port multiplier constitute a channel. \r
