why can't bios settings be stored on some kind of ROM?
why the fuck does it need 24/7 power?

aren't you that same low iq nigger that thought super capacitors solved the battery problem?

Welcome back, supercapacitor retard.
How's life in your 24 hour care facility these days?

>>105733460 (OP)
Nuclear Battery (Chink tech)
20y lifetime (don't peal off the seal)

>>105733492
Nigga they are stored in a ROM. The battery is for powering RTC circuit inside the chipset.

>>105733580
Nowhere near enough power to run an RTC.

Those are the replacement and thank god these pieces of motherboard-destroying shit aren't a thing anymore.

Firmware settings go to flash and the time comes from ntp.

Xbox didn't had that issue.

>>105733492
Only taiwanese gaymer toddlerware resets the "CMOS" when there is no power, enterprise hardware uses permanent uefi variables

>replacing a 20¢ battery that lasts 10 years with a 5000 dollars, radioactive battery that lasts 20 years
nope

CR2032: common but only lasts a few years
Bigger lithium batteries: can last for decades but hard to find, sometimes used on enterprise equipment, often soldered because they can last like 30 years
Supercap: limited lifetime, only hold charge for days/weeks, soldered, can leak, usually last longer than a CR2032
NiMh/NiCd/Alkaline: just don't.

>>105733736
yeah, until you realize that there is no such thing as a storage medium called "EFI variables", just like there is no storage medium called "Boot Sector".

But rather, those ominous EFI variables are stored inside an NVRAM, which is cheap shit that slowly gets destroyed by write operations.

Your "enterprise product" that highly depends on NVRAM doesn't use it because its le high quality, they use it because they are required to implement mandatory government approved spyware and the NSA certs are inside that NVRAM.

>>105733583
if they are stored in ROM why is it wiped as soon as i take the battery out?

>>105733812
Every UEFI uses NVRAM, but gaymer boards also use the CMOS to store a checksum, and if that checksum is missing, the variables are reset.
>that slowly gets destroyed by write operations.
How often do you think new variables are written?

>>105733808
a small solar panel, like calculator sized and a supercap lol

>>105733723
what am i looking at here? pls elaborate

And what anon doesn't mention is that the one in the xbox is notorious for leaking

>>105734030
>leaking
so, that killed the hype

>>105733460 (OP)
It just works.
Let me guess, you "need" more?

>very easy to replace
>lasts 10-20 years depending on use
it does the job just fine, i don't even understand how something like this can register as a problem to you

>>105733492
because then you couldn't change the settings genius.

>>105733583
no they are not stored in a ROM. Rom is read only. READ ONLY MEMORY. They are stored in an EPROM. The battery is for the eprom.

>>105733841
for the same reason it gets wiped when you short out the clrtc pins despite not removing the battery
it's just an intentional thing that was programmed in, even if the settings are stored on bios, removing the battery means you are most likely attempting to reset your bios, most people don't even know the clrtc pins exist, it's a QoL thing.

>>105733853
Which means that those gaymer products are better, since they don't rape an NVRAM.
>how often do you think efi variables are written
In enterprise products?
Probably every update, since they need to keep the spyware running. Bullshit like crowdstrike will rape that as well, since they have to fuck around with the boot process on every level.

>>105734794
>Which means that those gaymer products are better, since they don't rape an NVRAM.
They have to do it too, only a checksum is in the RTC as an emergency recovery of sorts.

>>105734714
Somebody should invent a ROM that you could write to more than once. And since it's already hooked up to electricity, you could find some way to use the electricity to do the erasing.
Then you just have to think of a clever name for this electrically erasable and programmable read-only memory. Something catchy like Dr. Humphrey's Magical Electrically Erasable and Programmable Read Only (but not really) Memory Chip That Doesn't Need a Fucking Battery. Or maybe shorten it up some. idk.

>>105733492

>Why can't I change my settings and store it on my read only memory

No clue.

>>105735687
when you save a file to a usb you can keep (read/write) the file saved for 10 years without power
maybe ROM wasn't the correct term, maybe just put a fucking 100MB flash chip on the mobo?

>>105735687
well you can use a ordinary sd card and write to it, push in the lock pin and turn it into a ROM card

>>105733492
How else can glowfrens access your data while your puter is turned off??
