ADV(4) Kernel Interfaces Manual ADV(4) NAME adv -- Advansys ISA/VL/EISA/PCI 8bit SCSI Host adapter driver SYNOPSIS For one or more ISA or VL cards: device isa device adv0 at isa? port ? irq ? drq ? For one or more EISA cards: device eisa device adv For one or more PCI cards: device pci device adv For one or more SCSI busses: device scbus0 at adv0 DESCRIPTION This driver provides access to the 8bit SCSI bus connected to the Advanced Systems Products, Inc. ASC900, ASC1000, ASC1090, ASC1200, ASC3030, ASC3050, and ASC3150 host adapter chips. The following tables list the Ad- vanSys products using these chips, their bus attachment type, maximum sync rate, and the maximum number of commands that can be handled by the adapter concurrently.

This board has been shipped by HP with the 4020i CD-R drive. The board has no BIOS so it cannot control a boot device, but it can control any secondary SCSI device. 2. This board has been sold by Iomega as a Jaz Jet PCI adapter. 3. This board has been sold by SIIG as the i540 SpeedMaster. 4. This board has been sold by SIIG as the i542 SpeedMaster. 5. This board has been sold by SIIG as the Fast SCSI Pro PCI.

Specific values for the port ad- dress, irq, and drq may be specified. If wildcard values are used, the driver will query the device for its current settings and use those. If the port address is a wildcard, the driver consults an internal table of possible port address locations and attaches to the first unattached card it finds. The possible port addresses for these card are 0x110, 0x130, 0x150, 0x190, 0x210, 0x230, 0x250, and 0x330. Per target configuration performed in the AdvanceWare menu, which is acces- sible at boot, is honored by this driver. This includes synchronous/asyn- chronous transfers, maximum synchronous negotiation rate, disconnection, tagged queueing, and the host adapter's SCSI ID. The global setting for the maximum number of tagged transactions allowed per target is not honored as the CAM SCSI system will automatically determine the maximum number of tags a device can receive as well as guarantee fair resource allocation among devices.
