Exista antivirus pt. BIOS

Boot Up Floppy Seek

Common Options : Enabled, Disabled

Quick Review

This BIOS feature determines whether the BIOS checks for a floppy drive during boot-up or not.

If enabled, the BIOS will attempt to detect and initialize the floppy drive. If it cannot detect one, it will flash an error message. However, the system will still be allowed to continue the boot process.

If this feature is disabled, the BIOS will skip the floppy drive check. This speeds up the booting process by several seconds.

Since a floppy drive check is really pointless, it is recommended that you disable this feature for a faster booting process.

Si atunci de ce mai afirma cei de la Gigabyte asta?
Cu "Boot up floppy seek" m-am lamurit , dar cum e cu DualBios-ul? Nu este el un antivirus?


offtopic:
De ce sa mai verifice daca am sau nu floppy, din moment ce eu oricum ii spun daca am sau nu (acolo unde iti definesti HDD-urile ai si optiuni pentru FDD, ca "none" (adica nu mai cauta degeaba, frate, ca nu am), 720k, 1.44M (adica da, am, crede-ma pe cuvint si nu mai cauta aiurea)

Chestia cu "floppy seek" este oarecum redundanta...

Pe mine nu ma convinge ca e antivirus.
Uite ce am gasit:

Gigabyte has also seen fit to include DualBIOS technology with the GA-7ZXR, which means two independent BIOS, and an extra layer of protection against viral infection; if the primary BIOS goes down, the secondary is still ready to go.

Adica - daca BIOS-ul se corupe, exista un back-up de pe care se boot-eaza. Cu extra layer de protectie nu stiu care e faza, cred ca e ceva atribut de read-only.

Ca sa fi si mai lamurit: http://www.findartic..._25/ai_54593975

Gigabyte motherboards with DualBIOS physically incorporate two BIOS chips. If the primary BIOS (the one booted under normal circumstances) fails, the secondary BIOS takes over on the next system boot.

Pana si numele DUALBIOS spune ceva - 2 BIOS-uri. Cel putin asa vad eu.

O tehnologie care previne/elimina efectul virusilor, mi se pare normal sa se numeasca "antivirus".
Tu din pacate intelegi prin cuvintul "antivirus" doar un soft care scaneaza niste fisiere pe HDD, incearca sa gindesti un pic mai pe larg.

Chiar si ce ai gasit tu, tot asta spune: "protection against viral infection" este un atribut al antivirusilor, oricum ar arata acestia.

format c: e un antivirus?!

dual bios de la Gigabyte inseamna ca ai 2 (doua) chipuri cu biosul inscris in ele. La bootare atunci cand se observa biosul principal are o corupere il copie pe cel secundar (din al doilea cip) si rebooteaza. Daca te uiti pe placa o sa vezi doua cipuri identice (doar unul cu eticheta in care spune ce model de bios are). Doar un virus am auzit ca poate corupe biosul (faimosul cih) dar nu am mai auzit demult de el! . cat despre protectia antivirus (cu care se lauda gigabyte) nu e preventiva ci ofera o solutie de backup!!!.  Cu toate ca mult mai probabil distrugi tu imaginea principala de bios decat un virus.

Da, este un antivirus, cu conditia sa ai un backup cu informatia neinfectata (exact ceea ce face DualBios).
Chiar as putea spune ca este cel mai bun antivirus.

Daca este o protectie antivirus, se poate spune despre acel produsul ca include un antivirus.

De ce spui asta? Ti se pare complicat conceptul de a avea doua biosuri?

Zi-mi si mie o "tehnologie" de asta. Eu credeam ca un antivirus detecteaza/dezinfecteaza/sterge sau pune in carantina fisiere care sunt suspecte/infectate.

Definitii:

Viruses - A virus is a small piece of software that piggybacks on real programs. For example, a virus might attach itself to a program such as a spreadsheet program. Each time the spreadsheet program runs, the virus runs, too, and it has the chance to reproduce (by attaching to other programs) or wreak havoc.
A computer virus must piggyback on top of some other program or document in order to get executed. Once it is running, it is then able to infect other programs or documents.

E-mail viruses - An e-mail virus moves around in e-mail messages, and usually replicates itself by automatically mailing itself to dozens of people in the victim's e-mail address book.

Worms - A worm is a small piece of software that uses computer networks and security holes to replicate itself. A copy of the worm scans the network for another machine that has a specific security hole. It copies itself to the new machine using the security hole, and then starts replicating from there, as well.
A worm usually exploits some sort of security hole in a piece of software or the operating system.

Trojan horses - A Trojan horse is simply a computer program. The program claims to do one thing (it may claim to be a game) but instead does damage when you run it (it may erase your hard disk). Trojan horses have no way to replicate automatically.

Ciocane si/sau magneti puternici pe HDD sunt antivirusi?! ))))

Sinteti circortasi.

Daca am eliminat virusul sau efectul lui folosind o facilitate a unui dispozitiv din sistem, atunci acel dispozitiv include un antivirus.

@Alucard
Cum e cu CIH, care afecteaza si BIOS-ul, nu numai fisierele de pe HDD? Vrei sa pui BIOS-ul in carantina, sau n-am inteles eu bine?

Daca noi suntem carcotasi, tu esti obtuz.
Cand CIH corupe BIOS-ul si poti sa pui tu mama antivirusilor, ca nu mai reusesti sa bootezi cum trebuie (sau chiar deloc), si nici sa rulezi vreun antivirus.
BIOS-ul se corupe, nu se viruseaza. Cat despre BIOS in carantina - incerci doar sa ma superi.
Have it your way.

Intervin preventiv   si va rog sa nu lansati atacuri la persoana.

Cand CIH corupe BIOS-ul, apesi F10 si rescrii bios-ul, pentru ca ai unul de rezerva.  Apoi, bootezi cu un CD/floppy bootabil si dezinfectezi restul.

Recunosc ca este un antivirus dedicat (dedicat CIH-ului), dar totusi este un antivirus.

Si fisierele corupte de virusi nu sint virusate? Cum adica, "BIOS-ul se corupe, nu se viruseaza. " Mie mi se pare ca chiar se viruseaza

Ideea cu carantina era ca un produs antivirus nu trebuie neaparat sa puna elementul infectat in carantina. Poate pur si simplu sa foloseasca o copie de backup pentru a elimina informatia corupta.


@Daisuke
Nu-i problema, dupa cum vezi, nu am ajuns inca la mame :D

Edited by ovidiugm, 28 February 2005 - 10:27.

Tu poti sa apesi F10, pentru ca ai placa aia, restul lumii ce face? Cam nasol.
De fisier corupt ai auzit? Hai sa stabilim o limita. Corupt nu inseamna virusat.
Ca sa iti dau un exemplu, ia sterge la tine in sistem boot.ini sau ceva de prin windows, o sa iti rezulte un sistem corupt. Nu unul virusat.
La fel se intampla si la BIOS.
Btw ... ma las pagubas. N-am vrut sa produc flame-uri si nici sa atac pe nimeni. He called names first.
Cel mai bine ne zice Daisuke, el e cel mai in masura sa ne spuna cum e cu antivirusii, si cu placa ta cu DUALBIOS.

The WIN95/CIH.1003 virus is of notable interest. It was first discovered in Taiwan in June 1998, and appeared here at Edinburgh in October. It infects Windows 95/98 executable files. The payload includes overwriting most of the hard disk. However, more serious is its attempts to overwrite the Flash BIOS chip of the machine. This will result in the infected computer being unable to boot. The Intel 430TX chipset for example is quoted as being vulnerable, though other Pentiums are at risk from this form of attack.

The most common version of the virus, CIH 1.2, activates on the 26th of April. At this time, it can overwrite the hard disk and the flash BIOS of an infected computer -- causing complete loss of data, and possibly rendering the computer unusable.

Eu am prezentat DualBios ca o posibila solutie antivirus (adica este ANTI VIRUSILOR, CONTRA, uite, ca sa reformulez. Si nu am spus ca ar fi preventiva, este doar curativa).

Intr-adevar trebuie sa ai placa Gigabyte, asa cum am spus la inceput.

Intrebarea era "Exista antivirus pentru BIOS"
Si raspunsul meu este "Da, DualBios este o solutie antivirus pentru BIOS"

Am zis ca ma las pagubas dar ...
Antivirus pentru BIOS-ul de la Gigabyte exista, pe langa Gigabyte mai sunt mii de firme care produc BIOS.

Pardon, nu antivirus. solutie back-up

de pe WIKIPEDIA citire:

Anti-virus software consists of computer programs that attempt to identify, thwart and eliminate computer viruses and other malicious software (malware).

A computer program (often simply called a program) is an example of computer software that prescribes the actions ("computations") that are to be carried out by a computer. Most programs consist of a loadable set of instructions which determines how the computer will react to user input when that program is running, i.e. when the instructions are 'loaded'.

Colloquially, the term program is often used interchangeably with software and software application.


Computer software (or simply software) refers to one or more computer programs and data held in the storage of a computer for some purpose


In computing, the Basic Input-Output System or BIOS is computer interface code that locates and loads the operating system into RAM.
