NAME
jmide -- JMicron Technology JMB36x PCIe to SATA II/PATA controller driver SYNOPSIS
jmide* at pci? dev ? function ? flags 0x0000 ahcisata* at jmide? DESCRIPTION
The jmide driver supports the JMicron Technology JMB36x IDE controllers. These PCI-e controllers exist in different flavors (1 or 2 PATA Ultra/133 ports and/or 1 or 2 SATA-II ports), and are highly flexible. The SATA ports can be attached to the integrated AHCI controller or attached to the PCI IDE channels in PATA emulation, in either single-drive emulation on each PCI IDE channels, or in master/slave emulation on one of the PCI IDE channels. When enabled, the AHCI controller can either be on the PCI function 0 or function 2. The PCI IDE controller can also be on either PCI func- tion, and can share the PCI function with AHCI. The jmide driver supports both the AHCI controller and PCI IDE controller in various config- urations. SEE ALSO
