# adv(4)

AdvanSys PCI SCSI interface

## NAME

**adv**, **adw** – AdvanSys PCI SCSI interface

## SYNOPSIS

**adv\* at pci?** **adw\* at pci?**

## DESCRIPTION

The **adv** and **adw** drivers support most AdvanSys PCI SCSI host adapters, as shown in this table:

| | |
| --- | --- |
| **adv** | **adw** |
| ABP-920 | ABP-940UW |
| ABP-930 (1) | ABP-940UWD |
| ABP-930U | ABP-970UW |
| ABP-930UA | ASB-3940UW-00 |
| ABP-940 | ASB-3940U2W-00 |
| ABP-940U | ASB-3950U160 |
| ABP-940UA |  |
| ABP-950 |  |
| ABP-960 (2) |  |
| ABP-960U (2) |  |
| ABP-970 |  |
| ABP-970U |  |
| ABP-980 |  |
| ABP-980U |  |

1. This board has been sold by SIIG as the Fast SCSI Pro PCI.

2. This board has been sold by Iomega as a Jaz Jet PCI adapter.

The **adw** driver will log some host adapter errors with general messages such as

```
adw0:0:0: host adapter error 0x12. See adw(4).
adw0:0:0: host adapter error 0x12, resetting bus. See adw(4).
```

Some further information on the meaning of such errors can be obtained from the following table derived from the source code provided by ConnectCom.
