# trm(4freebsd)

Tekram TRM-S1040 ASIC based PCI SCSI host adapter driver

## NAME

**trm** – Tekram TRM-S1040 ASIC based PCI SCSI host adapter driver

## SYNOPSIS

To compile this driver into the kernel, place the following lines in your kernel configuration file:

**device scbus** **device trm**

Alternatively, to load the driver as a module at boot time, place the following line in [loader.conf(5)](/loader.conf/5.md):

```
trm_load="YES"
```

## DEPRECATION NOTICE

This driver is scheduled for removal prior to the release of FreeBSD 13.0

## DESCRIPTION

The **trm** driver supports PCI SCSI host adapters based on the Tekram TRM-S1040 SCSI ASIC.

## HARDWARE

SCSI controllers supported by the **trm** driver include:

- Tekram DC-315 PCI Ultra SCSI adapter without BIOS and internal SCSI connector

- Tekram DC-315U PCI Ultra SCSI adapter without BIOS

- Tekram DC-395F PCI Ultra-Wide SCSI adapter with flash BIOS and 68-pin external SCSI connector

- Tekram DC-395U PCI Ultra SCSI adapter with flash BIOS

- Tekram DC-395UW PCI Ultra-Wide SCSI adapter with flash BIOS

- Tekram DC-395U2W PCI Ultra2-Wide SCSI adapter with flash BIOS

For the Tekram DC-310/U and DC-390F/U/UW/U2B/U2W/U3W PCI SCSI host adapters, use the [sym(4)](/sym/4.md) driver.
