User's Manual

Slot 8 contains the parallel and serial interface and floppy disk controller

card, and slot 9 contains the hard disk controller card. The video card must

be installed in slot 7. Slots 1, 7, and 8 are designed for 8-bit option cards and

the other six--slots 2 through 6 and 9-are designed for 16-bit option cards.

Figure 4-5 shows both types of cards. As you can see, the 16-bit card has a

second connector.

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 7. 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. Because the hard disk controller card must be con-

nected to the hard disk, this option card is in slot 9, where it is closest to the

hard disk. Leave it there.

Option cards fit in the slots only one way, but be sure to examine the

card first and follow the instructions closely.

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.
