be supported by one chassis. However, users can select
multiple extension chassis for different purposes. For exam-
ple, a 4-slot extension chassis provides small and compact
form factor while an 18-slot extension chassis provides
more PCI slots. Theoretically, PCI specification allows up to
255 PCI bus segments. ADLINK PCI Express
®
Bus Exten-
sion Products do not limit the bus segment number. The
maximum PCI bus segments may limited by your BIOS or
operating system.
Question: Is there any compatibility problems with the ADLINK
PCI Express
®
-to-PXI extension kit?
Answer: ADLINK PCI Express
®
Bus Extension Products are
designed as standard PCI Express
®
-to-PCI Bridge. During
PC boot up, your PC BIOS will search devices and assign
resources such as, I/O, memory space and IRQ number, to
each device according to its algorithm. Although PCI speci-
fication allows up to 255 bus segments in a PC system, the
BIOS may not assign the correct and/or proper resource to
each device in some complex PCI systems.
Because the PCI Express
®
specification was released in
2002, most hardware and circuit board designers as of yet
do not offer multiple PCI-to-PCI bridges. Most BIOS work
for simple applications but may not work for multiple PCI
bus segments and a variety of resource requests. We sug-
gest customers choose PC equipment with Intel 945, 965 or
later chipsets to adjust for these issues.
Question: When I encounter compatibility problems, what should
I do?
Answer: Because most compatibility problems come from PCI
resource assignments, customers should consult their PC
vendors or BIOS vendors for help. Updating to the most cur-
rent BIOS version may also resolve PCI resources prob-
lems.
