4. To terminate the last device on the SCSI chain, insert an active termination
device such as the IBM 68-pin External Multimode LVD/SE SCSI
Terminator. It inserts into the second connector on the last device in the
chain 2 .
5. Set correct SCSI ID for each SCSI device.
Step 11. Configuring the computer
To configure your computer, do the following:
1. Reconnect the power cord and other cables.
2. Turn on all attached devices; then turn on your computer.
3. For most computers, the computer performs a power-on self-test (POST)
and the configuration program automatically recognizes the new SCSI
adapter. However, you might have to answer questions about your system
changes when you restart you computer. If your computer does not
recognize the SCSI adapter after it starts up, enter the configuration
program and review the PCI configuration options. Some configuration
options apply to specific PCI bus slots. Be sure to change configuration
options for the PCI bus slot in which the SCSI adapter is installed. Read
your computer documentation if you are not sure which slot corresponds to
each number. Here are some things you might need to do while using your
computer configuration program.
v If there is an Interrupt Type or Interrupt Line option, select Int-A or
Interrupt Type = A. Depending on your computer design, you might
also be required to change a system board jumper setting.
v If there is a Triggering Interrupt option, select Level.
v If there is an option to enable or disable bus-mastering for the PCI slot,
select Enabled.
v If there is an option to enable or disable individual PCI slots, select
Enable for the slot in which you installed the adapter.
v If your computer has a combination of ISA (or EISA) and PCI adapters,
you might need to mark the IRQs used by ISA/EISA adapters as Used
so that the computer BIOS will not try to assign these IRQs to other PCI
adapters.
v In some computers the BIOS reserves a set of available IRQs for PCI
adapters. You might have to assign the adapter IRQ manually.
Refer to your computer documentation for more information. If you still
encounter problems during installation, see "Appendix D. Problem solving" on
page D-1.
