IIRC, nobody asked for UEFI/EFI. There was no and still can't see any benefit for the consumer to move away from a traditional BIOS.

They boot faster? What a selling point... They already hibernated/suspended at least as fast. EFI has always been about backdooring consumer devices.

"EFI enables vendors to create drivers that cannot be reverse engineered."

It's more anti right to repair shit from what I understand.

The thing wrong with BIOS is that it was extremely dated, and I'm not entirely sure it was codified. EFI has loadable modules and stuff. EFI has a shell. EFI is, perhaps, too complicated. But I could agree that BIOS needed a replacement. Plus, EFI unified different architectures a bit. BIOS was explicitly tied to x86 as far as I know. EFI can be used on ARM and others.

I though the appeal with UEFI was you can actually have really nice GUIs with pictures and mouse support in bios menus now.

I remember Pentium 1 motherboards with GUI and mouse support in their bios.

Taken from https://www.maketecheasier.com/differences-between-uefi-and-bios/ <---"BIOS uses the Master Boot Record (MBR) to save information about the hard drive data while UEFI uses the GUID partition table (GPT). The major difference between the two is that MBR uses 32-bit entries in its table which limits the total physical partitions to only 4. Each partition can only be a maximum of 2TB in size, while GPT uses 64-bit entries in its table which dramatically extends the support for size possibilities of the hard drive." Seems pretty useful to me.

I swear computers and smartphones are just designed with this shit from the factory.

I believe these are hacks. The backdoors that the government(s) put in are not publicized.

What? No way. I don't believe it. Can't be.

Its incredible how far left tech went over the last ~10yrs

My PC recently suffered a pajeet update and lost sound to my headphone jack.

Works fine through HDMI and the inbuilt speakers work.

But when I plug in headphones it detects it but no sound.

Downloaded numerous drivers still no sound.

[ - ] bonghits4jeebus 0 points 1.8 yearsJul 27, 2022 23:00:25 ago (+0/-0)

Can you get the old drivers somewhere?

[ - ] Clubberlang 0 points 1.8 yearsJul 28, 2022 22:14:47 ago (+0/-0)

I went back as far as 2015 still no sound.

Don't do anything electronically that you want to be private.

I see this as an argument for secure boot, although they could probably patch around that, too? It might be though that a TPM, if it were programmed properly and could only be erased with a physical button, could do its job of verifying the signature on a kernel.

rootkits are nothing new

[ - ] Kozel -2 points 1.8 yearsJul 27, 2022 16:34:39 ago (+0/-2)

Flashing an uninfected bios should clear the infection then.

[ - ] ThisGuy 1 point 1.8 yearsJul 27, 2022 19:42:58 ago (+1/-0)

Unless you wrote it how do you know it's uninfected?

[ - ] Kozel 0 points 1.8 yearsJul 28, 2022 03:29:40 ago (+0/-0)

read my comment again

[ - ] ThisGuy 0 points 1.8 yearsJul 28, 2022 03:50:44 ago (+0/-0)

Again. How do you know what you're flashing is uninfected?

once more read my comment

Did your parents have any kids that lived?

I'm sorry about your lack of intelligence.

I think it bricks the computer if you try to flash a UEFI BIOS

[ - ] bonghits4jeebus 0 points 1.8 yearsJul 27, 2022 23:01:40 ago (+0/-0)

It's on a SPI chip. At the least, you should be able to go and replace the chip with the original contents, if you can find them. At least, I don't think they lock those things. I have accessed PC BIOS chips externally before which contain, among other things, the EFI.
