A sto se tice update-a

1.     Check your BIOS for BIOS FLASH PROTECTION and make sure it's DISABLED, some motherboards have this function.
For Example:
K7N420 Pro (MS-6373) – BIOS setup/Integrated Peripherals/BIOS Protect/Disabled
2.    Find the exact model motherboard you have.
     a.    First check inside the motherboard bios, some motherboards, like the MS-7030, show the bios version in the bios, under Standard CMOS Features.
     b.    Open your case and look for the MS-XXXX number on the motherboard, using located between the PCI slots, also check the version number as well. (Some motherboards like the MS-6390 have different versions, in which each version uses a different bios)
     c.    Boot up your system & take a look at the top left screen during POST, you should see something like “W6390VMS v2.6 092903” This means the board is MS-6390 with BIOS version 2.6
     Hint: Many systems run to fast, that you will not be able to see this line, you can either press “PAUSE” key or you can disable the “Quick Boot” & “Full Screen Logo” options in the BIOS.
3.    Download the BIOS that match your motherboard model and version number. BIOS's can be found at this link, which are separated by CPU socket type (socket 775, socket 478, socket 754, socket A, and archives)
4.    Extract the BIOS that you have downloaded by double click it and extract it to a blank formatted floppy disk.
5.    Boot the system with a bootable floppy disk
     a.    A Windows 98/ME startup disk can be used
     b.    Or you can create an MS-DOS startup disk under Windows XP, to create an MS-DOS startup disk under Windows XP, right click on the 3 ½ floppy drive icon under my computer and select format. On the format dialog box, check the box next to “Create MS-DOS startup disk” and then click the start button to make a MS-DOS startup disk.
6    Once you boot off of the bootable floppy disk, replace the bootable floppy disk with the floppy disk containing the bios files.
7.    At the A:\ prompt, you will type in the following command
     a.    A:\FLASHUTILITY BIOSFILE.VER
     b.    The flash utility will be the .EXE file included in the BIOS you downloaded. For example: ADSFI712.EXE = BIOS FLASH UTILITY
     c.    The BIOS file will end with the version number you downloaded. For example:
A6728ims.210 = BIOS file version 2.10
8.    To update the BIOS using the example above you would type the following command.
     a.    A:\ADSFI712 A6728ims.210, then push the enter key.
     b.    Follow the onscreen prompts to update the BIOS.
9.    DO NOT TURN OFF THE POWER or RESET/REBOOT the SYSTEM before the BIOS update is completed, stopping the BIOS UPATE before it is completed will cause the system to become non-functional.
10.    Reboot the system once the bios update has been completed.

Da, imao sam dobru misao, ali sam pogreshno formulisao, skidanje jumpera vraca default-na podesavanja, ne i verziju Bios-a. . .
Ali, zato postoje flash-back porgrami. . .koji vracaju staru verziju.Jedan od njih se zove, neoriginalno - Bios i ima 24kb

Kako nesto moze da vrati prethodni BIOS, kada si ga ti obrisao? Jedino ako ploca nema Dual-BIOS.
Zato se i pravi kopija postojeceg BIOS-a, ako nesto krene naopako.

kako protice flashovanje biosa preko live update-a(za msi) mozete videti ovde:

http://www.msi.com.tw/html/products/liveupdate/step.htm

jedno pitanje vezano za postupak:
pod sl.16 ima da se uradi bios rescue disk i sada me zanima,jeli to ustvari backup starog biosa ili sta i ako jeste,kako se moze iskoristiti ukoliko se flashovanje zezne?

Ja bih vam preporučio da proverite prvo na sajtu proizvođača . .tj. na njihovom forumu ..
šta kažu korisnici za određene evrzije bios'a ..

Nikad nisam imao problema sa flešovanjem .. što live što sa diskete ..
elem .. sve dok MSI nije izbacio BAGOVIT bios .. koji po njima radi ok .
a mi korisnici smo tupavi ..i nismo pratili proceduru kako treba .. cvrc ..
Neću u detalje samo ću reći MSI k8n Neo Platinum i verzija biosa 1.9 ..

Morao sam reprogramirati bios i pljunuti 15'ak evrića .. + - ..
iz tehničke podrške MSI'a su me ubeđivali da sam ja to pogrešno odradio ..
preporučili mi bios 2.1 koji opet nije hteo da radi kakotreba .. znači opet sam sj*o bios ..
dok sa verzijom 1.7 radi ok ..

1. Poenta je da bios ostavite kako jeste ako sve radi kako treba
2. dobro se informišite šta koji bios donosi i nađete i neke mane koje eventualno donosi ali
proizvođač ih demantuje .. dok komuna priča na sva usta o tome ..

Ukoliko ste prilikom fleshovanja unistili boot deo flasha, i komp nece ni da se pokrene, probajte hot-flash, ja sam sinoc spasio jednu K8N NEO FSR, tako sto sm njen bios re-flashovao na jednoj K8N PLATINUM, i to radi...hot flash, podignes sistem pomocu boot-abilnog flopija na kome se nalaze i awdflash i zeljeni bios, zatim dok komp radi skines bios sa ploce (ja sam koristio srafcigercice sa buvljaka one najmanje izolirane selotejpom), ubacis osteceni bios i pokrenes flash, i kad se sve zavrsi ugasis komp izvadis bios koji je bio los, vratis stari i to je to....ne das krvopijama 15e...1.9 ver stvarno lose radi....1.7 je ver koja kod mene radi stabilno. Poz svima

ko se ne razume nek ne radi to 

Ja u zivotu nesto ne bih skidao sa maticne ploce, jos dok komp radi, hehe! 
Ma najsigurnije je lepo napravis disketicu sa prethodnim i jednostavno ga vratis, ako se bas nesto zezne.

A sa koja 2 pina na koja 2 se preba prebaciti?

Mislis za clear CMOS? Za to ti treba sema maticne ploce. Uglavnom postoje neka tri pina u blizini baterije i onda (kada je iskljucen racunar) treba prebaciti dzamper i posle ga vratiti kao sto stoji!
