Adapter and Device Configuration
Manual No. 3000863 3-5
When there are multiple adapters, the adapter with the highest BIOS address
controls the process of reading data from other adapters for configuration
information.
Modifying Adapter Configuration
The list of options on the right side of the screen may be modified
To change a value for an option, do the following:
1. Highlight the desired parameter using the arrow keys and press the
<Spacebar>.
2. For example, when you select the SCSI ID parameter and press the
<Spacebar>, a popup menu listing possible values for this parameter
appears. Use the arrow keys to choose a new value from the popup list
Port Address This field shows the base address of the registers the host uses
to communicate with the host adapter. Each board and each
channel within the same host system must have a unique I/O
port address to prevent hardware conflicts. On PCI adapters, the
host system’s BIOS assigns the I/O port address during the boot
sequence.
PCI Bus # This field shows the PCI bus number.
PCI Device # This field shows the PCI device number
SCSI Channel The channel on the FlashPoint LT that is being configured.
IRQ
Channel This field shows the hardware interrupt line (IRQ) number that
the adapter uses to generate interrupts to the host. The adapter
issues an interrupt whenever it requests attention from the host.
On PCI adapters, the host system’s BIOS assigns the IRQ
value.
Termination This field indicates whether the adapter’s automatic SCSI
termination, SmartTerm is turned on or not. SCSI devices are
daisy-chained together and a terminator is required at each end
of the chain. Should the selected adapter be at the beginning or
the end of the SCSI chain, this value must be set to AUTO.
Termination is enabled/disabled automatically by the FlashPoint
host adapter.
