This type of information is stored in battery-backed RAM so that it retains the setup information when the power is turned off. This chapter explains the setup utility for the Award BIOS. Entering Setup To enter setup menu, power on the computer and press <Del> immediately will allow you to enter Setup. The other way to enter Setup is to power on the computer, when the below message appears briefly at the bottom of the screen during the POST (Power On Self Test), press <Del> key or simultaneously press <Ctrl>, <Alt>, and <Esc> keys. TO ENTER SETUP BEFORE BOOT UP PRESS CTRL-ALT-DEL KEY If the message disappears before you respond and you still wish to enter Setup, restart the system to try again by turning it OFF then ON or pressing the "RESET" button on the system case.

Die einzelnen Funkti- onseinheiten des Pentium Prozessors werden grob skizziert. Das besondere Au- genmerk schließlich gilt der Darstellung des im Koprozessor der CPU aufgetre- tenen Divisions-Fehlers, dessen ¨offentlicher Entdeckung sowie der Erl¨auterung dessen technischer Ursachen und wirtschaftlicher Folgen. Der Ursprung des Feh- lers liegt in einer unvollst¨andig ub¨ ertragenen Divisionstabelle, auf die der SRT- Divisionsalgorithmus zuruc¨ kgreift, und die dem Koprozessor falsche Werte zur Berechnung liefert. Der Divisions-Fehler im Pentium war die bisher gr¨oßte von der Offen¨ tlichkeit erzwungene Ruc¨ krufaktion. 2 Kapitel 2 Intel Die Intel Corporation wurde 1968 von Robert Noyce und Gordon Moore ge- grundet.¨ Der Schwerpunkt der Entwicklung und Produktion lag bei Halbleiter- Speichersystemen. Im November 1971 brachte Intel seinen ersten Mikroprozes- sor auf den Markt, den 4004i.1 Er besaß 2.300 Transistoren und hatte einen 4 Bit breiten Datenbus und einen 12 Bit breiten Adressbus mit dem insgesamt 4 KByte Speicher adressiert werden konnte.

Il nuovo socket viene definito ZIF (Zero Insertion Force ) in quanto l'inserimento della CPU non richiede alcuna forza contrariamente ai socket LIF ( Low Insertion Force ) i quali, oltre a richiedere una piccola pressione per l'inserimento del chip, richiedono anche appositi tool per la sua rimozione. Il modello di socket ZIF installato sulla motherboard è, in genere, indicato sul socket stesso. Tipi diversi di socket accettano famiglie diverse di processori. Se si conosce il tipo di zoccolo montato sulla scheda madre è possibile sapere, grosso modo, che tipo di processori può ospitare. Il condizionale è d'obbligo in quanto per sapere con precisione che tipi di processore può montare una scheda madre non basta sapere solo il socket ma bisogna tenere conto anche di altri fattori come le tensioni, il FSB, le CPU supportate dal BIOS ecc. Nel caso ci si stia apprestando ad aggiornare la CPU è meglio, dunque, attenersi alle informazioni sulla compatibilità fornite dal produttore della scheda madre.

To manage these conflicts, power system designs: maximum performance some designs imposed instruction-issuing per watt of power consumed. The challenge of constraints on the theory that application the 5x86 design was to achieve compelling programs could be recompiled quickly and system performance at no more than half the easily (based on knowledge of the instruction power consumption of competing solutions. issuing rules and restrictions) to optimize code That goal was achieved by critically evaluating flow. Examples of this approach include the the costs (measured in power and transistor PowerPC 601Ô, HP-PA7100Ô and the Intel count) versus the benefits (measured in PentiumÔ processor - CPUs that can issue two performance) of key architectural features. This instructions simultaneously but only under analysis enabled the careful selection of restrictive, special-case conditions. These architectural features that deliver the desired conditions are more of a limitation for the performance at less than half the power Pentium since the majority of the software it consumption of competing fifth-generation executes will be from the installed base of x86 alternatives.

  • Biostar MB-8433UUD Manual Revision
    Biostar MB-8433UUD Socket 3, 486 Motherboard (UMC 8881/8886) Manual revision 2.0 Overview The MB-8433UUD is a generic, 486-class, PCI/ISA motherboard from Biostar Microtech of Taiwan. This company was also known as BMA in the USA, and Bioteq in Europe. Many other companies, including Quantex Computers, MINT-data, Pantex Computer, CyberMax Computers, Pionex Computers, San Carlos Computers, and TC Computers, sold the MB-8433UUD, and other Biostar motherboards, under different names. The MB-8433UUD may have been sold in the USA as MBD-4PB2 and MBD-4MB2. The MB-8433UUD‘s sold new in 1997 for $99 USD, or about the same price as a PC Chips M919. The MB-8433UUD was one of the more stable PCI-based 486 motherboards produced. The board is loaded with over- clocking features, boasting a FSB range of 20-83 MHz, and contains the highly sought-after 1:2/3, 1:1/2, and 1:1 FSB-to-PCI multiplier settings. It is one of the few Socket 3, PCI 486-class motherboards to fully support the Intel Pentium Overdrive (POD-83) in write-back (L1) mode. The BIOS firmware designers, and/or UMC chipset designers, also had the foresight to include support for the Cyrix/IBM 5x86 (80-133 MHz) CPU in linear burst mode. This is one of the few motherboards to work reliably with all of Cyrix’s 5x86 5th generation features enabled (via software). The motherboard routinely works with an AMD X5-133 @ 160 MHz, and is one of only two boards reported which have successfully run an AMD Am5x86/X5-133 @ 200 MHz (5V).
