3.7 PCI Bus

		Some floppy power connectors are smaller than the standard connector, and most power supplies come with one of these plugs. These connectors can only be installed one way.

		For data, a flat ribbon cable is needed. It is gray with 34 conductors and a red stripe to indicate pin 1. One end of the cable will usually have a twist in it. The twisted portion connects to a second floppy drive (drive B:). The end farthest from the twist connects to the motherboard or floppy controller.

		VGA card installation

		If the motherboard has an integrated video adapter, go to step 3.

		Plug the VGA card into the appropriate slot, depending on the type of card purchased (PCI slot for a PCI card, ISA slot for an ISA card.

		Screw the top of the metal bracket that is attached to the adapter into the case using one of the screws supplied with the case.

		Monitor

		Plug it into a wall power outlet.

		Plug the video input plug, which is a 15-pin connector, into the back of your video card.

		3.10.4 Booting the System

		Setup is where you configure your motherboard's components, peripherals, and controllers. It is usually in ROM and can be run by pressing a certain key during POST. Check the CMOS settings using the setup program before booting for the first time. If you make changes, you will need to exit setup and save changes to CMOS for them to take effect. You will be able to change the date and time kept by the RTC (real time clock). Memory configuration like shadow RAM and read/write wait states can be changed from their defaults. IDE hard disks can be detected and configured. Boot sequence and floppy drives can be configured and swapped. PCI cards and even ISA cards can be configured, and PnP disabled (which should be done if running a non-Windows OS). ISA bus speed can be changed and ports can be enabled or disabled.

		IDE disks are almost always configured as Auto detect or user-defined type. Use shadow video unless you have problems. Shadow the ROM of your NIC or SCSI card for better speed. For better speed and if you have EDO memory, you can usually use the most aggressive memory settings - just try it out before you stick with it to avoid corrupting data files.
