jmb — JMicron
JMB36x SATA II and PATA Host Controller
jmb* at pci?
ahci* at jmb?
pciide* at jmb?
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 but only one driver per PCI
device can be attached, the jmb driver acts as a
nexus to other drivers that support the SATA and PATA functionality.
ahci(4) supports the SATA
functionality, and pciide(4)
support the PATA functionality on these controllers.
The jmb driver first appeared in
OpenBSD 4.2.
The jmb driver was written by
