Solve : bios install? |
Answer» Hi all, most motherboard have a small ROM chip as well though that, if the normal BIOS is corrupted can be used to flash straight from a floppy. Doesn't have anything else; just the flashing ROM. Really? I wasn't aware of that, of course I'd never had a need to find it. Can you supply some DOCUMENTATION I could peruse through?Actually, I was only partially correct. It's not actually a seperate chip, but rather a special area in the start of the BIOS called the Boot Block. http://forum.overclock3d.net/showthread.php?324-Motherboard-BIOS-Flashing-Guide Quote
Even so, newer PCs literally have two Duplicate BIOS chips. Mine has two, so if a flash fails or something it runs off the backup. Nice, thanks for the heads up BC. I thanked you for that one, you know, in case you care Quote from: Quantos on January 14, 2010, 08:39:36 PM Really?BC is no too sharp on hard ware. OK, he got you the docs. A portion of the FLASH is "blown" at the factory so that it ca not be erased. The remainder can still be flashed. That part is ROM. The ROM will READ a prepared floppy and re do the flash. This is documented somewhere in the Intel motherboards. Don't know which and not sure if it is still done that way. Quote from: Geek-9pm on January 14, 2010, 08:49:54 PM BC is no too sharp on hard ware. not too sharp... but that's essentially what I just said! that "blown" flash that cannot be erased is the boot block... unless of course this is your dictation program causing confusion Yes, BC. Basically you had it right. That is old technology and I was just talking off the top of my head. Little bit of research with Google shows that everybody is repeating the same words that they found somewhere about the accidental rewrite of the BIOS. According to one popular source there may have been only one well known virus that actually attacked the flash BIOS. I think it was called the Chernobyl virus. But it only affected certain Intel motherboards anyway. I just did a Google search on some of this to try to bring my memory back and it appears that now days they think the possibility of a BIOS virus is rather rare. This is because most i386 operating systems will not allow direct access to the hardware that does the flash. So you have to boot the system with the DOS floppy and run the program in that environment. That being said, it would seem very unlikely that the OP had a virus in his firmware. And I scratched out that part where I said you were too sharp on hardware. Actually you did WHETHER rather well. If he's running a 286 he'd have to worry about a BIOS infection....unlikely. Bios & Boot Sector viruses are indeed extremely rare. Then again, so is a response from the OP.Hi All, Sorry I didn't resond to all you kind people, but I do have to work. I found the problem, besides a virus I also have a bad HDD. Problem solved. Thanks for your help |
