Bios Configuration

Bios Configuration

Whichever method you’ve used to update your BIOS, it’s important that the new BIOS Setup defaults are used when the system is next powered on. You can do this by entering Setup by pressing the appropriate key – generally DEL as soon as POST starts and by then selecting the option to Load BIOS Setup Defaults from the Main Menu.
Alternatively, you can discharge your CMOS RAM before restarting your computer – so as to ensure that the BIOS Setup defaults from the new BIOS chip are used. Most motherboards will have jumpers to enable you to do this. Typically this is a three-pin arrangement in which on pair of pins are jumpered to retain your CMOS data and the other to clear your CMOS. With the system powered off and its power cable removed, clear your CMOS by shorting the appropriate pair of pins and then revert to the normal jumper position before turning the system on.
Return to the Main Menu and – using the record you made previously – go through each of the BIOS screens in turn editing settings as appropriate to ensure that the same customisations that had been applied to your previous BIOS version are configured for your new BIOS. You’ll also need to set the correct system date and time.
Your system will now use your updated BIOS to boot to Windows.
The BIOS has evolved very little since the birth of the PC in 1981, remaining a chunk of hand-crafted assembly language code most users know only for the series of arcane configuration and test messages fleetingly displayed when they turn on their PC.
Intel first signalled that all that was about to change in early 2000, with the release of the first version of its Extensible Firmware Interface (EFI) specification, a proposed standard for the architecture, interface and services of a brand new type of PC firmware, designed to provide a well-specified set of services that are consistent across all platforms.
EFI is effectively a tiny operating system in its own right, complete with its own basic networking, graphics, keyboard and storage handling software. This will allow it to have a radically different user interface to what we’ve been accustomed to, with support for high resolution displays and a proper GUI. The differences are far more than cosmetic though.
Since EFI is able to manage its own storage space – normally envisioned as a partition on a hard disk – hardware manufacturers will be able to add many more diagnostic and control options, and include support for different kinds of computer systems and configurations, without being constrained by the cost of expensive onboard flash memory. Moreover, the fact that EFI is developed in a high-level programming language will also spur innovation, allowing additional features to be created using standard programming tools. Such additions can include much more detailed and useful diagnostics, self-configuration programs and ways to sort out problems even if the operating system has died. Since it has its own networking capability, EFI will also be able to support remote diagnostics.

Processors (CPUs)

Processors (CPUs)

The CPU, or Central Processing Unit, is the core of any computer, and, through the latter half of the 20th and into the 21st century, it has arguably been fundamental in revolutionising the way that mankind lives and works.
The real anchor point was perhaps the 1978 introduction of Intel’s 8088 microprocessor to IBM’s first PCs. Developments since then have been truly extraordinary, from basic dual processor solutions to those pushing at the very boundaries of science

AMD technology

AMD are undoubtedly in the shadow of Intel still, but they have been far more than a chip cloning operation. Their work is often underrated, and has many times given a real challenge in performance compared to Intel’s more pricy market equivalents.

Celeron CPUs

Originally developed to compete with other “budget” level CPUs in 1998, over time the Celeron succesfully carved a useful place in the CPU market.

CPU Architecture

Behind the complexity, learn the fundamental principles in the design and make-up of a microprocessor.

Cyrix CPUs

Once an innovative challenger in the CPU race of the 1990s, the legacy of Cyrix CPUs has been in more than lowering processor costs.

Intel Core CPUs

All good things must come to an end, and in the summer of 2006 Intel’s Netburst microarchitecture and Pentium processor dynasty was finally superseded by a new generation of CPU.

Pentium CPUs

Intel’s Pentium chips set the computer market alight in the 1990s. Find out the reasons for this chip family’s long lasting success.

Chipsets

Chipsets
A chipset or “PCIset” is a group of microcircuits that orchestrate the flow of data to and from key components of a PC. This includes the CPU itself, the main memory, the secondary cache and any devices situated on the ISA and PCI buses. The chipset also controls data flow to and from hard disks, and other devices connected to the IDE channels. While new microprocessor technologies and speed improvements tend to receive all the attention, chipset innovations are, in fact, equally important.
Although there have always been other chipset manufacturers – such as SIS, VIA and Opti – for many years Intel’s “Triton” chipsets were by far the most popular. Indeed, the introduction of the Intel Triton chipset caused something of a revolution in the motherboard market, with just about every manufacturer using it in preference to anything else. Much of this was down to the ability of the Triton to get the best out of both the Pentium processor and the PCI bus, together with its built-in master EIDE support, enhanced ISA bridge and ability to handle new memory technologies like EDO and SDRAM. However, the new PCI chipsets” potential performance improvements will only be realised when used in conjunction with BIOSes capable of taking full advantage of the new technologies on offer.
During the late 1990s things became far more competitive, with Acer Laboratories (ALI), SIS and VIA Technologies all developing chipsets designed to operate with Intel, AMD and Cyrix processors. 1998 was a particularly important year in chipset development, with what had become an unacceptable bottleneck – the PC’s 66MHzsystem bus – to finally being overcome. Interestingly, it was not Intel but rival chipmakers that made the first move, pushing Socket 7 chipsets to 100MHz. Intel responded with its 440BX, one of many chipsets to use the ubiquitous Northbridge / Southbridge architecture. It was not long before Intel’s hold on the chipset market loosened further still, and again, the company had no-one but itself to blame. In 1999, its single-minded commitment to Direct Rambus DRAM (DRDRAM) left it in the embarrassing position of not having a chipset that supported the 133MHz system bus speed its latest range of processors were capable of. This was another situation its rivals were able to exploit, and in so doing gain market share.
The following charts the evolution of Intel chipsets over the years, from the time of its first Triton chipset. During
this time there have also been a number of special chipsets optimized for the Pentium Pro or designed for use with notebook PCs.

    DENGAN 1 DAN ANGKA ITU SENDIRI
    $n = ...; // silakan masukkan nilai N di sini
    $status = "PRIMA";
    for ($i = 2; $i <= $n-1; $i++)
    {
    if ($n % $i == 0) 
    {
    $status = "TIDAK PRIMA";
    break;
    }
    }
    echo "Bilangan ".$n." adalah : ".$status;
    ?>
    Hasilnya akan seperti ini:
    bila kita masukan angka 2 di $n maka akan muncul
    "bilangan 2 adalah : prima"

    Cara mengkoneksi database mysql dengan php
    Untuk melakukan koneksi ke MySQL ada dua fungsi yang bisa digunakan. Yang pertama adalah dengan menggunakan fungsi mysql_connect. Sintaks fungsinya adalah sebagai berikut.
    resource mysql_connect ( [string server [, string username [, string password [, bool new_link [, int client_flags]]]]])
    Contoh penggunaannya adalah sebagai berikut ini. $conn = mysql_connect('localhost', 'root', 'passwordku');
    if (!$conn) {
    die('Koneksi ke MySQL gagal: ' . mysql_error());
    }
    echo 'Koneksi ke MySQL sukses dengan mysql_connect !!';
    mysql_close($conn);
    ?>


    Kita lihat di atas ada perintah mysql_connect yang fungsi utamanya adalah untuk melakukan koneksi ke database MySQL. Sebagai contoh di atas server MySQL ada di localhost dengan username root dan passwordnya adalah passwordku. Ada catatan penting yang harus diingat di sini. Sejak versi 4.1, MySQL sudah mengunakan sistem autentikasi protokol yang baru yang berbasis pada algoritma hashing. Hal ini membuat koneksi yang menggunakan client lama akan gagal dan akan menghasilkan error message seperti berikut ini.
    Client does not support authentication protocol requested by server; consider upgrading MySQL client
    Tidak usah takut. Penulis sendiri mengalami hal sama ketika melakukan uji coba dengan PHP 4.3.11 dan MySQL 4.1.11 ini. Solusinya mudah dan ada beberapa cara. Menurut pada manual MySQL 4.1.11, hal tersebut bisa diatasi dengan cara reset password dari user sehingga bisa diakses oleh client versi yang lama. Ini dilakukan dengan menggunakan perintah SET PASSWORD dan juga fungsi OLD_PASSWORD(). Contoh untuk melakukannya adalah sebagai berikut.
    mysql> SET PASSWORD FOR
    -> 'some_user'@'some_host' = OLD_PASSWORD('newpwd');
    Anda bisa mengganti 'some_user' dengan user yang Anda gunakan dan 'some_host' dengan host Anda (biasanya localhost). Kemudian pada bagian newpwd isikan dengan password Anda.
    Persistent connection
    Selain menggunakan fungsi mysql_connect, bisa juga dengan menggunakan fungsi mysql_pconnect. Apa bedanya? Ini adalah fungsi koneksi ke MySQL dengan cara persistent. Sekali kita koneksi secara persistent ke database server maka koneksi ini terus melangsungkan hubungan ke database server. Secara prinsip fungsi mysql_pconnect ini sama dengan mysql_connect hanya saja dengan dua perbedaan yaitu:
    1. Selama mengadakan koneksi maka fungsi ini akan mencari suatu link persistent lain yang sudah terhubung ke host, user dan password yang sama. Jika link tersebut ditemukan maka identifier dari koneksi atau link tersebut akan diberikan ke client dan client tidak akan mengadakan koneksi baru ke dataase server.
    2. Koneksi ke database tidak akan terputus jika eksekusi dari suatu script SQL selesai dilakukan. Pada fungsi mysql_connect, secara otomatis koneksi akan terputus sesaat setelah suatu script SQL dieksekusi. Pada fungsi mysql_pconnect, koneksi ke database akan terus terjadi dan tidak akan diputus walaupun Anda menggunakan fungsi mysql_close.
    Sintaks dasar dari penggunaan fungsi mysql_pconnect adalah sebagai berikut.
    resource mysql_pconnect ( [string server [, string username [, string password [, int client_flags]]]])
    Contoh code PHP nya dari fungsi mysql_pconnect bisa dilihat pada code berikut ini. $conn = mysql_pconnect('localhost', 'root', 'ariesa2001');
    if (!$conn) {
    die('Koneksi ke MySQL gagal: ' . mysql_error());
    }
    echo 'Koneksi ke MySQL sukses dengan mysql_pconnect !!';
    ?>


    yang jelas mesti buat script utk koneksi database contohnya koneksi.php

    Scr garis besar codenya spt ini :


    $host="localhost";
    $username="root";
    $password=

    $database="nama databasenya";

    //buat koneksinya
    $conn=mysql_connect($host,$username,$password)

    //buat cek koneksinya

    if(!$conn)
    {

    echo("Koneksi Gagal");

    }

    $hasil=mysql_select_db($database);
    if(!$hasil)
    {

    echo("Database Gagal");

    }

    ?>
