Back in the old days (10+ years ago) there were all these nice little tricks to reset and fix stuff, like shorting the JBAT jumper to reset the BIOS setup data memory, or removing the battery, or press-holding a special key when powering on and so on. On some machines one could even just unplug the BIOS chip and reflash it in another device. Some of this stuff was sometimes even in the official manuals.
But what are the possibilities on modern machines? What "low-level" tricks exist here? Most modern Laptops (and even desktops) don't have a BIOS battery, some don't even have the JBAT jumper to short the power of the memory, with all the ACPI and UEFI stuff the BIOS's are extremly integrated and often can't even be identified when looking on the plain mainboard. The manuals nowadays normally don't have any hints about BIOS stuff (no idea why are power users are forgotten, even they can't "magically know" all the non-standard/brand-dependend details for new devices)...
Is there a good overview about these low-level tech details for most modern devices?
Low-level tricks for (BIOS) resetting/hacking on modern machines?
