Conventional PCI

The first PCI bus had a 32-bit data path, supplied 5 V of power to an expansion card,

and operated at 33 MHz. It was the first bus that allowed expansion cards to run in sync

with the CPU. PCI Version 2.x introduced the 64-bit, 3.3-V PCI slot, doubling data

throughput of the bus. Because a card can be damaged if installed in the wrong voltage

slot, a notch in a PCI slot distinguishes between a 5-V slot and a 3.3-V slot. A Universal

PCI card can use either a 3.3-V or 5-V slot and contains both notches (see Figure 3-11).

Conventional PCI now has four types of slots and six possible PCI card configurations to

use these slots (see Figure 3-12).
