# stg(4freebsd)

driver for Future Domain based SCSI controllers

## NAME

**stg** – driver for Future Domain based SCSI controllers

## SYNOPSIS

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

**device scbus** **device stg**

For one or more ISA cards: **device isa**

In */boot/device.hints*: **hint.stg.0.at="isa"**

For one or more PCI cards: **device pci**

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

```
stg_load="YES"
```

## DESCRIPTION

The **stg** driver provides support for ISA, PCCARD and PCI controllers based on Future Domain SCSI controller chips including the TMC-16C30, 16C50 and 32C60.

## HARDWARE

Controllers supported by the **stg** driver include:

- Adaptec 2920/A

- Future Domain SCSI2GO

- Future Domain TMC-18XX/3260

- IBM SCSI PCMCIA Card

- ICM PSC-2401 SCSI

- MELCO IFC-SC

- RATOC REX-5536, REX-5536AM, REX-5536M, REX-9836A

Note that the Adaptec 2920C is supported by the [ahc(4)](/ahc/4.md) driver.
