1.
A 64-bit card can be installed in a 32-bit slot. However, this card will only operate in 32-bit mode.
2.
A 66 Mhz card can be installed in a 33 MHz slot. However, this card will only operate in 33 MHz mode.
3.
A 33 MHz card can be installed in a 66 MHz slot, However, the card will operate in 33 MHz mode and will force all other PCI devices to operate
at 33 MHz as well.
4.
A 32-bit card can be installed in a 64-bit slot without preventing other 64-bit PCI devices to operate in 64-bit mode.

Accessory Card Slots
If an AGP Pro card ( 25 W and 50 W) is installed, then the PCI slot 1 is
made inaccessible as defined in the AGP Pro specification (PCI slot must be
left unoccupied to provide its sources, in terms of cooling and electrical
power, to the AGP Pro card. The following table shows the various PCI
board installations for the different PCI slots:

The system board and BIOS support the PCI specification 2.2. This
specification supports PCI-to-PCI bridges and multi-function PCI devices,
and each of the five PCI slots have Master capabilities.
PCI slots 1, 2 and 5 are connected to the ICH PCI 32-bit 33 MHz bus, while
PCI slots 3 and 4 are connected to the PCI 64-bit 66 MHz bus via the P64H.
In addition to these PCI slots, the following devices are also connected to a
PCI Bus:
