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.
