1747-UM001A-US-P - March 2000
Defining System Settings 5-7
Two 1747-OCKTX, -OCKTXD channels can share a PCI interrupt only if
the drive software supports shared interrupts. For more information, see the
A-B Communication Interface Module User Manual, publication
1747-6.18.
Defining interrupts for the open controller SCANNER
•
The open controller API and the open controller diagnostic software use
IRQ 11 by default, and can automatically detect which interrupt is
assigned to the scanner.
Defining Drive Types Corresponding master and slave devices must be on the same open
controller module. For example, if the FlashDrive is a primary master, you
cannot have a primary slave on an IDE interface module. Likewise, if a
PCMCIA interface module is a secondary master, you cannot have a
secondary slave on an IDE interface module.
You cannot have a slave drive without a master drive. For example, you
cannot have a CD-ROM connected to an IDE interface module secondary
channel and set it up as a slave (via jumpers on the CD-ROM) unless the
same IDE interface module already has a secondary master.
On the 1747-OCE with AMIBIOS version 1.04 or earlier only: Since the
PCMCIA interface module does not use its assigned PCI interrupt, it can
share that interrupt with a 1747-OCKTX, -OCKTXD module.
If you have a: Then:
1747-OCE
•
Keep IRQ 11 defined as ISA/EISA so that it does not get assigned to
open controller option modules.
•
Make sure that no other devices, such as Ethernet cards or
1747-OCKTX, -OCKTXD channels, are assigned to IRQ 11.
1747-OCF
•
Keep IRQ 11 defined as PCI.
•
Make sure that no other devices, such as 1747-OCKTX, -OCKTXD
channels, are assigned to IRQ 11.
