They added code to the #BIOS that, when signaled to do so by the operating system, would instruct the keyboard controller to reset the CPU. The BIOS would begin executing as in a normal reboot, but instead of its usual start-up routine, it would immediately hand control back to the operating system, now running in real mode.
Clever though this was, it was also terribly slow, and therefore most PC/AT software did not use the 286's new protected mode.
@gettie I mean, yeah #ARM & #ARM64 ain't "#mainstream" -yet.
That being said I'd still prefer some craptastic chinese netbook simply because it has some regular-ass #UEFI / #BIOS and I can shove any OS on it that I want...
Coucou,
j'ai récup à la poubelle un hp élite d'entreprise sous windows 11, que j'aimerais évidemment passer sur debian, sauf qu'il y a un mot de passe sur le bios qui m'empêche d'y accéder, et vu que j'ai récup l'ordi à la schlague je peux pas contacter le constructeur. Le bios est uniquement accessible via windows, c'est protégé via hp secure boot.
Quelles pistes pour virer le mot de passe et booter sur ma clé d'installation la linuxteam ?
J'ai vu la possibilité de démonter l'ordi et enlever la batterie de la carte mère mais j'ai vu des avis divergents sur cette technique.

Does anyone have ideas or implementations on how to operate a #BIOS without sighted help? I keep having the problem of changing BIOS settings or boot sequences and always need someone to help me with the settings. I've also tried the video recognition of #ChatGPT or #Gemini, but both were way too imprecise and often just made up what it read to me or recommended for control. #accessibility #linux #server
Thanks to @geerlingguy for addressing the elephant in the room.
@RaspberryPi dominates the #SBC market because they know how to write #documentation and build #drivers that get accepted into #mainline #Linux kernel.
dd onto a microSD!That's why my #BananPi Zero M2 is still unused to this day: It's way too inconvenient and whilst I do want to support it someday, it's just not a good start when the 1st #RasperryPi's documentation to this day is still the bare minimum and vendors can't be assed to do that.

Interesting article and something that everybody should be aware of.
BIOS under attack: hackers increasingly focus on boot threats.

Ok, I spent yesterday afternoon trying to get #RAID configured on my #lenovo #ThinkPad #P70 - to no success.
I found this video https://www.youtube.com/watch?v=AyCC1NGe8a8&t=36s of the similar #p50 and configuring #RAID which shows the #BIOS interface but my P70's only show the "non-raid physical discs" I do not have an option for RAID volumes. Note I have upgraded the BIOS to the most recent version on lenovo's web site. Any thoughts?
I have attached 2 #screenshots of what the BIOS displays - I'm trying to configure the RAID on the two 512GB #NVMe sticks.

TL;DR: #GRUB assumes that the file system is valid, and might execute arbitrary code if it isn't.
That is a perfectly valid assumption…or it would be if #Microsoft wasn't still trying to ice-skate uphill by pushing #SecureBoot.
News flash, Microsoft: Secure Boot is only secure if the #BIOS is secure, and I'm sorry to break it to you but that is absolutely hopeless.
@tofugolem
Don't You hate it that there's no standard way to access the #BIOS?
It's always a matter of endless restarting to find the right key. 
#BIOS / #OpenFirmware in the '90s stored settings (boot order, etc) in battery-powered SRAM. If the battery died, all such settings were lost as soon as the computer was powered off.
I wonder if any BIOS developers ever considered storing this information in a partition on the hard drive itself? No worries about the battery then.

Like, sure, define a new partition table format; the old one sucked anyway. By all means, define a partition type for holding the bootloader; hiding it in the void between partitions was a horrible idea.
But for goodness' sake, the #BIOS does *not* need to read a file system, giving it a #networking stack is outright dangerous, and for video just use VBE3 like a normal person!
The #IBMPC #BIOS has an awful lot of functions that really belong in the operating system's device drivers, not machine firmware.
Most of them ended up being straight-up useless. Programmers would routinely bypass them and poke hardware registers directly instead.
#Intel, learning absolutely nothing from this, went on to develop #EFI and #UEFI.
The ‘Titan’ GPU released in 2013 originally retailing for nearly $1000, which I purchased for £25 in a recent auction. However, it suffered from a crippling “code 43” issue.
This is my journey...
