Computer Installation

Computer installation is the fundamental step, which flutes life to your dead hardware component. Computer installation may be studied under two categories, the former is the hardware installation and the later as software installation.

Let's get acquainted with the hardware installation under this article. This will be helpful for making self installation. After going through this article you will be able to perform installation of hard drive along with making partition.

You must consider some basic rule. If you are going to install two hard drives or IDE devices over the same IDE Channel (controller), you need to configure the jumper. They should be set as Master and Slave so that they are able to perform with the same IDE cable. On an average there are two IDE Channels (Primary and Secondary) on one motherboard for a total of four IDE devices allowed per system. Let's assume, if there is one HD and a CD-ROM integrated then you can assemble two more hard drives. You can also do installation of extra hard drive and IDE backup devices.

Steps for initiating computer installation

STEP 1. Turn off the power and remove all cables from the back of the computer.

STEP 2. Gently remove the case screws and remove the case cover.

STEP 3. Secure the Hard Drive into the mounting bay using appropriated screw.

STEP 4. Analyze the configuration of the computer for the presence of any extra IDE port on your current IDE cable(s). If there is one IDE cable, which is already engaged with two IDE devices then you need to incorporate extra IDE cable in order to facilitate the entry of additional hard drive.

STEP 5. Plug in the new or spare IDE port to the new hard drive.

Note: Always insert Red pin closest to the 4-pin Power.

STEP 6. Insert the P4 Power cable into the new hard drive.

STEP 7. Without making mistake put the case cover back onto the case and secure it with the case screws that were previously removed.

STEP 8. Plug all required cables into the computer and then power up the system.

STEP 9. Explore Computer CMOS and use the Auto IDE Detection feature and then save the changes and exit. This will reboot your computer.

STEP 10. Hence, the hard drive is mounted and connected.

Creating partition is another important step towards computer installation.

STEP 1. After getting the hard disk recognized under BIOS, you will need a Bootable Diskette which must contain Files: Fdisk.exe and Format.com. The diskette you use should be a bootable diskette.

STEP 2. Place the bootable diskette into the 1.44MB floppy drive and turn on the computer.

STEP 3.. Wait for the "A:>" prompt, type DIR and it should show three files, Fdisk.exe, Format.com and Command.com.

STEP 4. Now, a Partition is needed so that DOS and Windows will see the new hard drive. At A:> type Fdisk then press enter.

STEP 5. At the Fdisk Menu, create a new partition and select #1 and press Enter.

STEP 6. Then Select #1 for Primary DOS partition and press Enter. Similarly user can increase number of partition.

STEP 7. Fdisk will ask for the size of the partition various sizes of partitions to a hard drive.

STEP 8. Fdisk will ask the End-user to give desired name, if a name is not desired the press Enter when prompted. Reboot the system.

Above computer installation steps would save your valuable time and money.

AC duct design?
I would like know what calculations are needed to design a residential AC system. I am certain the system in my house is improperly sized and the duct system is inefficient. I would like to confirm. Thanks

Is there an HVAC standard for minmum amount of air that comes out of a residential AC vent?
The vents in my house do not appear to be pushing out that much air. The smaller rooms get cool with the doors shut. But overall it takes a long time to cool the house 1 degree (about 2.5 hours) My AC unit has been tested and is cooling properly, but I believe it isn't pushing out enough air to cool the house effectivly.

Anyone on here Residential AC experts?
I need some help solving a problem. I'm on my second ac unit in 7 years. This first unit a carrier I went thru 3 compressors. I installed an Amana last year in July and it's now having problems. It never cuts off in the afternoon and the compressor is sweating bad and possibly freezing up. The refrigerant is at capacity. It is a 4 ton unit and a split system. All components ar matched however it appears that the gas returning to the compressor is not completely returning as a gas but some liquid. The condenser and metering device and blower are matched for a 4 ton unit. I have 14 3 x 10 vents and I think the static pressure is hindering the flow of air needed. I made contact with the company who manufactured the condenser and they said its specs are for a 4 ton unit at 0 static pressure. I don't know how they figure a unit will ever have 0 static pressure when it has to be vented but that's what they said. Do you think the condenser and metering device are the problem? The blower is performing at specs, the coolant level is at capacity, the ducts, filter coils everything is cleaned far beyond what should be reqiured. I have checked everything and the only conclusion I can come up with is that there is not enough air being pulled over the coils due to static pressure. I'm considering trying a 5 ton coil, metering device and blower if it will physically fit.
