What happens when you install a 66Mhz, 32-bit PCI card in a 33MHz, 64-bit PCI slot?

Question

Options

• AThe 66MHz, 32-bit card operates at 33MHz in 64-bit mode.
• BThe 66MHz, 32-bit card operates at 66MHz in 32-bit mode.
• CAll 33MHz, 64-bit cards on the PCI bus operate like 33MHz, 32-bit cards.
• DThe 66MHz card operates at 33MHz.

Explanation

The rules that govern the use of PCI cards are as follows: A 66MHz PCI card can be used on a 33MHz PCI bus. A 33MHz card in a 66MHz PCI bus automatically operates at 33MHz. A 32-bit PCI card can be installed in a 64-bit PCI slot. A 64-bit card can be installed in a 32-bit slot and will work in 32-bit mode. A PCI bus can be so heavily used that it becomes a performance bottleneck. It is best to plan for optimal performance when configuring the PCI devices. To provide optimal configuration: 1. Match 66MHz slots with 66MHz devices. 2. Match 32-bit slots with 32-bit devices. 3. For the remaining devices, proceed as follows: If you have available 32-bit slots, place the minimum number of 64-bit devices in the 32-bit slots, using the devices with the lowest throughput. If you still have more devices than available 64-bit slots, the 66MHz slots will have to run at
