IDA(4) BSD Kernel Interfaces Manual IDA(4) NAME
ida -- Compaq Intelligent Drive Array Controllers SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file: device scbus device ida Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): ida_load="YES" DESCRIPTION
The Compaq Intelligent Drive Array (IDA) technology is used to distribute data across an array of hard drives. It unites these hard drives into one or more high-performance logical drives. The drive array is managed by an array controller. These controllers have the ability to provide fault tolerance for the connected drives and optionally provide write cache for the logical drives. It is also possible for an application to access the SCSI bus subsystem directly by using the pass-through interface. HARDWARE
The following controllers are supported by the ida driver: o Compaq SMART Array 221 o Compaq Integrated SMART Array Controller o Compaq SMART Array 4200 o Compaq SMART Array 4250ES o Compaq SMART 3200 Controller o Compaq SMART 3100ES Controller o Compaq SMART-2/DH Controller o Compaq SMART-2/SL Controller o Compaq SMART-2/P Controller o Compaq SMART-2/E Controller o Compaq SMART Controller IMPLEMENTATION NOTES
Extreme caution should be exercised when using the pass-through interface. It is possible to interfere with normal system I/O and cause hangs if pass-through is used to an active device. Pass-through should only be used to a device that is otherwise quiescent. SEE ALSO

TL(4) BSD Kernel Interfaces Manual TL(4) NAME
tl -- Texas Instruments ThunderLAN Ethernet device driver SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file: device miibus device tl Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): if_tl_load="YES" DESCRIPTION
The tl driver provides support for PCI Ethernet adapters based on the Texas Instruments ThunderLAN Ethernet controller chip. The ThunderLAN controller has a standard MII interface that supports up to 32 physical interface devices (PHYs). It also has a built-in 10baseT PHY hardwired at MII address 31, which may be used in some 10Mbps-only hardware configurations. In 100Mbps configurations, a National Semiconductor DP83840A or other MII-compliant PHY may be attached to the ThunderLAN's MII bus. If a DP83840A or equivalent is available, the ThunderLAN chip can operate at either 100Mbps or 10Mbps in either half-duplex or full-duplex modes. The ThunderLAN's built-in PHY and the DP83840A also support autonegotiation. The tl driver supports the following media types: autoselect Enable autoselection of the media type and options. Note that this option is only available on those PHYs that support autonegotiation. Also, the PHY will not advertise those modes that have been explicitly disabled using the following media options. 10baseT/UTP Set 10Mbps operation. 100baseTX Set 100Mbps (Fast Ethernet) operation. 10base5/AUI Enable AUI/BNC interface (useful only with the built-in PHY). The tl driver supports the following media options: full-duplex Force full duplex operation. half-duplex Force half duplex operation. hw-loopback Enable hardware loopback mode. Note that the 100baseTX media type is only available if supported by the PHY. For more information on configuring this device, see ifconfig(8). HARDWARE
The tl driver supports Texas Instruments ThunderLAN based Ethernet and Fast Ethernet adapters including a large number of Compaq PCI Ethernet adapters. Also supported are: o Olicom OC-2135/2138 10/100 TX UTP adapter o Olicom OC-2325/OC-2326 10/100 TX UTP adapter o Racore 8148 10baseT/100baseTX/100baseFX adapter o Racore 8165 10/100baseTX adapter The tl driver also supports the built-in Ethernet adapters of various Compaq Prosignia servers and Compaq Deskpro desktop machines including: o Compaq Netelligent 10 o Compaq Netelligent 10 T PCI UTP/Coax o Compaq Netelligent 10/100 o Compaq Netelligent 10/100 Dual-Port o Compaq Netelligent 10/100 Proliant o Compaq Netelligent 10/100 TX Embedded UTP o Compaq Netelligent 10/100 TX UTP o Compaq NetFlex 3P o Compaq NetFlex 3P Integrated o Compaq NetFlex 3P w/BNC DIAGNOSTICS
