Rant: You don't overclock using the BIOS?!?!? - Page 3

post #21 of 38
CMOS is basically the bios memory, so yeah, we are changing the CMOS to tell the bios what to do

It does nothing to the BIOS. The BIOS loads the settings off the CMOS RAM. The BIOS is READ ONLY.

Its kinda like viewing and altering your files through windows, when someone is trying to explain something they dont say go into windows, theyd say go into drive c or whatever (although windows is on the hard drive, and cmos isnt on the bios but you get my drift)

Am i correct?
No it'd be like writing a batch file to start C:\\Lollookimaexecutablefle.exe, again ROM = Read Only Memory. The settings you can change are store on the CMOS.

So we are still telling the BIOS what to do them? That's a relief. Sometimes that turd of a chip can get ****y, so you have to yell at it an sometimes beat it to submission, or sometimes even flash it (preferably with a sharp object) so it knows who's boss.

Think of it like this, CMOS is a floppy disk (or your choice of media). You run a program that has the ability to have customized settings, but the program is encoded into ROM - Read-Only Memory. So for the program to get its custom settings, it checks the floppy disk, which is rewritable.

Technically, BIOS is encoded into EEPROMs (Electronically Erasable Programmable Read-Only Memory). The CMOS is essentially a tiny RAM (Random Access Memory) chip, used to store the custom settings for the BIOS EEPROM.

On a side note:
When you Flash your BIOS, you are electronically erasing the EEPROM and reprogramming it. (On older boards with EPROMs, you actually have to remove the EPROM, remove a sticker, hit it with UV, then reprogram it with an EPROM programmer.)

That actually sounds more fun than simply hitting a key.

Lol it's not hard to grasp. The BIOS has nothing of the CMOS in it.

The BIOS asks the CMOS "Hey mate what should we do with this CPU?"
The CMOS checks his RAM and says "Oh lord he wants it at 500 and vcore at 1.375..."
The BIOS not knowing what else it should be happily say "Oi CPU Freq, get yer ass to 500!!"
The CPU Freq by this time (whacked on lots of voltage) is like "LAWLZ OK GUY WHEEEE"
Then the BIOS asks the CMOS "Hey what about this whacky ram sticks?"
The CMOS looks back at his RAM and says "Hmm well he's got it at 1:1 and 2.2v on the sticks"
BIOS goes over to the ram sticks swats the coffee out of their hands and shouts "Hey you slackers coffee breaks over, Get over there in dual channel @ 1:1 with 2.2 volts!"

By this time the drives come in late (again) and the BIOS says "Hey CMOS what about these clowns?"
CMOS looks up and says "That one's a DVD ROM the other is a 250GB and the last one's a 60GB get the 250GB ready to load the OS, it's first in the boot sequnce if he should fail kill him and let the DVDROM carry out his mission"

Anyways so the OS kicks in and is like "RAWRRRGH I IZ ALIVE!!"
The CMOS chuckles and knocks off since his job is done and the OS and BIOS hang out for the rest of the day discussing that new hottie in the graphics department.

Huh, very good info man. Didn't know about the older EPROMs. Were the EPROM programmers easily attainable, or hard to get/rare/expensive?

I love that explanation. Its dead-on and something that alot of non-techies would understand.
