Installing Windows XP Professional SP2 on Acer Aspire 5315-2153 Laptop There are two methods for getting this to work, one only requires the internet, a few minutes, and a CD burner. The other requires a USB floppy drive. UPDATE: We’ve got a working modem driver now. Check out the tutorial on getting it up and running (should be installed last). You’ll probably also need a USB thumb drive for either method, and of course your copy of WinXP. You may have already tried to install WinXP on this notebook. With the BIOS set to it’s defaults, the WinXP install disk can’t even see it’s Hard Drive, and if you set the hard drive to a non AHCI mode in the BIOS (such as native emulation), you are increasing your risk of data corruption, and at the same time reducing your speed. These two methods are the correct way to handle the situation, and result in no performance compromises. NOTE: All data on the hard drive will be erased. If you experience problems related to .DLL files, try DLLCentral.com for resources and downloads. The Floppy Method First we’ll explain the floppy method, as it’s the fastest if you’ve already got the floppy drive and a blank floppy. Download the floppy creator from here: f6_floppy_maker.zip Extract the executable from the zip archive, insert a blank floppy, and run the executable, following the prompts to create an “F6 Driver Floppy.” Attach your USB floppy drive to the new Acer notebook. In order to be able to boot from the CD, we’ll first need to make a couple of quick changes in the notebook’s BIOS. Click here for instructions on modifying the BIOS settings. Now boot your notebook from your WinXP install disk. One of the first prompts once the screen turns blue is to hit F6 to use a driver floppy. Hit F6, insert the driver floppy. Windows won’t really give you any prompt that you’ve done things right, it will just keep installing for a while. After some time, windows will ask you to pick which driver off of the floppy you want — you should choose “Intel(R) 82801HEM/HBM SATA AHCI Controller (Mobile ICH8M-E/M).” Be sure to leave the floppy in during the install, as windows will periodically pull files off of it until the installation is complete. The Windows installer will ask you to where you’d like install Windows XP… follow the prompts to delete all the current partitions, then follow the prompts to create a new partition, and install Windows XP to that. You may chose the “quick format” to speed things up. After windows is done installing, you’ll need to install some drivers. Acer isn’t providing a driver set for WinXP on this notebook. We recommend installing drivers in this order:...

Disassembling the Xbox 360 Slim To get into the Xbox 360 you’ll need pretty much the same tools you needed to get into the old one. A flat head screwdriver helps, preferably one with a long, thin stem to help you pry bits of the case apart. You’ll need a torx driver with T8 bit. As always, proceed at your own risk - we're not responsible for any damage to your console that happens as a result of following these instructions. Also know that proceeding with this will surely void your warranty from Microsoft. 1. First remove the 2.5" hard drive. To get to it just pull back on a couple of the fins which will let you remove a part of the cover: 2. Yanking on the black ribbon will pull out the hard drive itself. 3. Next we have two plastic grates on the left and right of the system that pop right off. They are attached using clips along their edges so work one part out with your flat head driver and just pull the rest off. 4. The side without the hard drive pops out just as easy. I used the thin screwdriver to prize up one end of the plastic grate and pulled it the rest out with my fingers. Be careful not to scratch the case. 5. This next part is the first of two hard parts. Removing the two plastic grates will reveal two more black plastic covers. You can wedge your flathead between the plastic cover and the rest of the system and pry it off. TIP: Some users remove the chrome surrounds without taking out these black plastic covers - so you could always skip parts 5, 6, 7 & 8 and go straight to removing the chrome bezels (Note: some slims that are refurbs have the matt black plastic case and the bezels are black not chrome) - all you have to do it unclip one side of the black plastic cover to reveal the chrome bezel clips so you simply unclip one side then the rest should pull out easily. I only include these separate parts of the tutorial so you can actually see what each piece looks like 6. The cover is attached to the system by several plastic stands that fit through little holes behind them. The stands are wider at their outer most edge than they are at the base, too wide to just fit through the hole.

This tutorial presents an introduction to the Quartus R II CAD system. It gives a general overview of a typical CAD ﬂow for designing circuits that are implemented by using FPGA devices, and shows how this ﬂow is realized in the Quartus II software. The design process is illustrated by giving step-by-step instructions for using the Quartus II software to implement a very simple circuit in an Altera FPGA device. The Quartus II system includes full support for all of the popular methods of entering a description of the desired circuit into a CAD system. This tutorial makes use of the schematic design entry method, in which the user draws a graphical diagram of the circuit. Two other versions of this tutorial are also available, which use the Verilog and VHDL hardware description languages, respectively. The last step in the design process involves conﬁguring the designed circuit in an actual FPGA device. To show how this is done, it is assumed that the user has access to the Altera DE2 Development and Education board connected to a computer that has Quartus II software installed. A reader who does not have access to the DE2 board will still ﬁnd the tutorial useful to learn how the FPGA programming and conﬁguration task is performed. The screen captures in the tutorial were obtained using the Quartus II version 8.0; if other versions of the software are used, some of the images may be slightly different. Contents: Typical CAD Flow Getting Started Starting a New Project Schematic Design Entry Compiling the Design Pin Assignment Simulating the Designed Circuit Programming and Conﬁguring the FPGA Device Testing the Designed Circuit 1 Computer Aided Design (CAD) software makes it easy to implement a desired logic circuit by using a programmable logic device, such as a ﬁeld-programmable gate array (FPGA) chip. A typical FPGA CAD ﬂow is illustrated in Figure 1.
