For information about the attributes, consult the online help. However, some explanation is warranted here:

￿Current Speed, Max Slot Speed: As described in 1.8, “PCI subsystem” on page 23, the adapters installed in this slot and other slots in the same bus dictate the speed that the slot will run at. Consequently, the current speed of the slot may not be the maximum possible speed. The “X” in the Current Speed value indicates the slot is running in PCI-X mode (as opposed to running in PCI mode).

Some RXE-100 slots may indicate “NS” for the slot speed (see Figure 5-6 on page 136 for an example). NS stands for “not set”. These are even-numbered slots when the odd-numbered slot in the pair is running at 133 MHz. This is because if both slots in a pair are used, the maximum speed of both slots is 100 MHz.

￿PME Signal: PME (power management events) is a hardware signal that some PCI slots can supply. Most PCI cards do not implement PME and the x440 and RXE-100 slots do not support PME.

￿Bus Number: a system-assigned number for each bus. Useful for identifying slots that are on the same bus, but the bus number does not correlate to the slot numbers.

￿Low Profile: The slot only supports cards that have a half-height end plate. See the PCI Special Interest Group specifications of low-profile PCI adapters at http://www.pcisig.com/data/specifications/lowp_ecn.pdf.

￿LED Status: Table 5-1 shows the possible LED status messages and their meanings:
