+.Sh NAME
+.Nm jmb
+.Nd JMicron JMB36x SATA II and PATA Host Controller
+.Sh SYNOPSIS
+.Cd "jmb* at pci?"
+.Cd "ahci* at jmb?"
+.Sh DESCRIPTION
+JMicron JMB36x hardware can provide support for SATA devices using the Advanced
+Host Controller Interface for Serial ATA, and for PATA devices using PCI IDE
+controller specification.
+Since support for both SATA and PATA devices can be enabled on the same PCI
+device and we can only attach one driver per PCI device, the
+.Nm
+driver acts as a nexus to other drivers that support the SATA and PATA
+functionality.
+.Xr ahci 4
+supports the SATA functionality on these controllers.
+.Sh SEE ALSO
+.Xr ahci 4 ,
+.Xr intro 4 ,
+.Xr pci 4
+.Sh HISTORY
+The
+.Nm
+driver first appeared in
+.Ox 4.2 .
+.Sh AUTHORS

+The
+.Nm
+driver was written by
