Except for the video card, it does not matter which slot an option card occupies, as long as the card fits in the slot. For example, you can place some 8-bit cards in a 16-bit slot. But if an 8-bit card has an additional skirt along the bottom (which looks like an extra long connector), it must go in an 8-bit slot.
The video card must be installed in slot 5. See Figure 4-4 to see how the slots are numbered. Also, some other cards must be installed in a specific slot. If you have such a card, the instructions that come with it specify which slot you need to use.
Option cards fit in the slots only one way, but be sure to examine the card first and follow the instructions closely.
1.Decide which option slot you want to use. If the card has an external connector (such as a monitor card), you need to remove the option slot cover at the back of that slot. See Figure 4-6. Remove the retaining screw from the top of the metal option slot cover and keep it to secure the option card to the computer, Lift out the slot cover and keep it in a safe place in case you remove the option card later.
