For most people, you turn on your computer, and it starts the operating system. However, the reality is much more complex as [Thasso] discovered. Even modern x86 chips start in …read more Continue reading A 64-bit x86 Bootloader from Scratch
[Hunter Adams] has written a secondary bootloader for the RP2040 that uses an IR link and can be extended to behave like a polite worm virus. This allows the easy …read more Continue reading RP2040 Boot Loader is a Worm
While things like the Arduino platform certainly opened up the gates of microcontroller programming to a much wider audience, it can also be limiting in some ways. The Arduino IDE, …read more Continue reading Blinkenlights to Bootloader: A Guide to STM32 Development
The Raspberry Pi was a fairly revolutionary computing device when it came on the scene around a decade ago. Enough processing power to run a full Linux desktop and plenty …read more Continue reading Using An Old Smartphone In Place of A Raspberry Pi
The ThinkPad line of laptops has been widely prized not only by businesses but also by those who appreciate a high standard of hardware quality and repairability. But some think …read more Continue reading Getting The Most From Fading ThinkPads
You have to be pretty ambitious to modify a clock to run for 50 years on a single battery. You also should probably be pretty young if you think you’re …read more Continue reading Low-Power Challenge: Making an Analog Clock Into a Calendar With a 50-Year Life
If there’s one thing we’ve learned over the years, it’s that if it’s got a silicon chip inside, it could be carrying a virus. Research by one group focused on …read more Continue reading Trojans Can Lurk Inside AVR Bootloaders
Dualbooting your computer can be a chore, the more switching between OSes you have to do – which is why virtualization or having separate computers are the go-to for many. …read more Continue reading Simple Hardware Switch For OS Dualbooting, Thanks To RP2040
Flashing your code into an Arduino, an ESP32 or any other modern microcontroller platform is pretty straightforward: connect the device through USB, fire up the appropriate software platform, and press …read more Continue reading Wireless Bootloader Saves You From Swapping ROM Chips
Traditionally, a forum full of technical users trying integrate their own hardware into a game system for the purposes of gaining unfettered access to its entire software library was the kind of thing that would keep engineers at Sony and …read more
