[[<bus_hex>]:]
[<slot_hex>]
[.[<func_int>]]

Enter the bus, slot, and/or function address, such as 00:1b:3 or :1b or :1b.4, to filter the list of PCI buses.

Valid ranges vary by which are currently used. For example, a specific FortiMail may now be using only the bus addresses 00, 13, and 1b. For a list of currently used addresses, enter:

diagnose hardware pciconfig

[<vendor_hex>]:[<device_hex>]

Enter the vendor and/or device identifier, such as 15ad:07b0, to filter the list of PCI devices.

<data_str>

Enter the data to send to the PCI device.

Valid length varies by whether the register is a byte, word, or long data type.

<register_hex>[.{B | W | L}]

Enter the hexadecimal register number (capability) of the PCI device, such as 2c. Optionally also suffix the data type (valid length of data) of the register, such as 4.b, where:

• B — Byte.

• W — Word.

• L — Long.

byte <address_hex> [<data_hex>]

Enter the hexadecimal address of the input/output port, and the hexadecimal byte of data to send to it. To read a byte from the device, omit the data sent.

long <address_hex> [<data_hex>]

Enter the hexadecimal address of the input/output port, and the hexadecimal long of data to send to it. To read a long from the device, omit the data sent.

option {v n t x H1}

Select which PCI bus information display options to use:

• v — Verbose.

• n — Number of the vendor and device instead of looking it up in the PCI ID list.

• t — Tree format that shows connections between the buses, bridges, and devices.

• x — Hexadecimal dump of the standard part of the configuration space (varies by the bridge, but could be the first 64 or 128 bytes).

• H1 — Hardware direct access.

pciconfig

Display a list of PCI buses, slots, functions, vendors, and devices.

For example, in this output:

1b:00.0 Class 0200: 15ad:07b0 (rev 01)

• 1b — Bus

• 00 — Slot

• .0 — Function

• 15ad — Vendor

• 07b0 — Device

setpci

Set a register on one or more PCI devices.

To set registers on one device, start the next argument with d.

To set registers on multiple devices in the same or different slots, start the next argument with s.
