4. Continue building new computers
   ( Procedure)

 Pick up shell computer and parts kit. Your parts kit should originally have had the following:
     CD-ROM drive
     hard disk
     floppy drive
     cable for floppy drive, CD-ROM, and hard disk (we'll use one cable for both cd and hd drive)
     Video Adapter Card
     Network Interface Card     
    
     Today, we will attempt to finish installing cards and drives, boot the computers, and take a preliminary hardware inventory

Pick up necessary screws at front of the lab
      (at least two thinner, smaller screws for the hard disk and cd-rom,
       medium-sized screws to hold cards in place, thick screws to fasten case cover).

Check jumper settings for drives. Hard drive should be set as master drive. CD-ROM        drive should be set as slave drive. (Hold drives carefully, and remember to ground        yourself once in awhile by touching the metal case of the computer.

Mount floppy drive, CD-ROM and hard disk in the computer's drive bay,(make sure no chips on  the  bottoms of the drives are touching the metal surface of the drive bay). Fasten  screws and attach ribbon cable and Molex power cables.

Place the video adapter and the network card in appropriate slots and fasten screws.

Make sure the red stripe faces the right way. Be careful not to bend pins on the drives  or on the motherboard.  Attach the ribbon cables to the floppy controller and Primary IDE Controller on the motherboard. (If you're not sure which one is which, ask for help.)

Attach the molex and mini-molex (berg) power connectors for the CD, hard drive, and floppy driv. Don't force anything.

Plug the power cable into back of the case.  Connect the cables for the monitor,  mouse, and keyboard and boot the computer.

What signs should you look for to see whether the computer is starting up properly?

T he computer may not recognize or boot from the hard disk. How can you confirm this?

_________________________________


Will the computer boot from the floppy drive with the Windows Startup disk?

__________

If the computer boots to the A prompt, enter the command DIR C:\ to see if a partition     has been configured for the hard drive.

If you don't see a C partition, enter the command FDISK and wait for instructions
to determine whether the hard disk is recognized, and how to create a partition, if necessary.

Homework:

Finish filling in blanks on Day 6 or Day 7 Agenda sheet (they're identical)
Study Meyers Lab 2.1, if you have the manual.

Read FDISK.DOC, instructions for partitioning and formatting a hard disk under DOS/Windows 9.x.

See MCMCSE Study Guide- Processors for more notes on CPUs http://www.mcmcse.com/comptia/aplus/notes/processor.shtml

See Geek.com (http://www.geek.com/procspec/procspec.htm) for a near-complete listing of Intel CPUs.
See Erols com (http://users.erols.com/chare/sockets.htm) and CPU Socket and Slot Criteria for pictures and info about CPUs, sockets, and slots.

On Wednesday, if all goes well, we will finish partitioning and formating the hard drives on the new computers.
