Balthazor 1 Report post Posted January 18, 2006 ala jangan rasa rendah diri plak. ok ape. jawapan ko tu betul secara amnya.yang aku nak butir2 atau perinci apa yang CPU buat masa mula2 ON komputer.kerja CPU saat2 awal. Masa nie skrin masih 'blank' & 'black' ←You press the "On" button on the computer and the monitor. You see the BIOS software doing its thing, called the power-on self-test (POST). On many machines, the BIOS displays text describing such data as the amount of memory installed in your computer and the type of hard disk you have. During this boot sequence, the BIOS does a remarkable amount of work to get your computer ready to run. The BIOS determines whether the video card is operational. Most video cards have a miniature BIOS of their own that initializes the memory and graphics processor on the card. If they do not, there is usually video-driver information on another ROM on the motherboard that the BIOS can load. The BIOS checks to see if this is a cold boot or a reboot. It does this by checking the value at memory address 0000:0472. A value of 1234h indicates a reboot, in which case the BIOS skips the rest of POST. Any other value is considered a cold boot. If it is a cold boot, the BIOS verifies RAM by performing a read/write test of each memory address. It checks for a keyboard and a mouse. It looks for a PCI bus and, if it finds one, checks all the PCI cards. If the BIOS finds any errors during the POST, it notifies you with a series of beeps or a text message displayed on the screen. An error at this point is almost always a hardware problem. The BIOS displays some details about your system. This typically includes information about the following: Processor Floppy and hard drive Memory BIOS revision and date Display Any special drivers, such as the ones for SCSI adapters, are loaded from the adapter and the BIOS displays the information. The BIOS looks at the sequence of storage devices identified as boot devices in the CMOS Setup. "Boot" is short for "bootstrap," as in the old phrase "Lift yourself up by your bootstraps." Boot refers to the process of launching the operating system. The BIOS tries to initiate the boot sequence from the first device using the bootstrap loader.

TonikCapGajah2013 175 Report post Posted January 18, 2006 (edited) panjang nya jawapan.aku baca dengan teliti jawapan yang diberikan.Hanya ada satu perkaan PROCESSOR sahaja. Dan tidak menerangkan fungsi processor.Apa yang processor buat? Itu persoalannya.Hmmm... TQ. Cuba lagi.clue: keadaan nie boleh terjadi semasa salah overclock.**hadiah menjadi Misteri 64 X2 sekarang nie. Edited January 18, 2006 by OngBok Quote Share this post Link to post Share on other sites

TonikCapGajah2013 175 Report post Posted January 25, 2006 BAHAGIAN 4KUIZ # 7Apakah operasi/perkara yang pertama dilakukan oleh CPU bila komputer mula dihidupkan?sudi-sudikan lah mencawab. terima kasih.←Perkara pertama:CPU menerima isyarat dari power supply --> semua voltan yang digunakan oleh perkakasan bersesuaian (tidak over/under voltage). Keadaan ini dipanggil 'power good signal' (guna google untuk search perkara nie). Serentak dengan ini BIOS akan menghantar isyarat kepada CPU melakukan tugas2 seterusnya.Tolong sambung .....
