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:

  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.
