System Address Map Initialization Part 2 Article

Finally, System Address Map Initialization Part 2 article is up. Check out :  http://resources.infosecinstitute.com/system-address-map-initialization-x86x64-architecture-part-2-pci-express-based-systems/. It's a lengthy article. There could be minor error coz I didn't have enough time to review some parts of the detail close to the end of it.

System Address Map Initialization in x86/x64 Architecture Part 1 - Article

New article explaining details of PCI-based system address map initialization is up: http://resources.infosecinstitute.com/system-address-map-initialization-in-x86x64-architecture-part-1-pci-based-systems/. This is part one of two articles. I started with PCI because the basic knowledge on the bus protocol is essential before moving to part two which covers present day PCIe systems.

UEFI EDK II on ARM (BeagleBoard) and My Next Article

I haven't been checking out TianoCore for a while and when I did, I stumbled upon this: http://sourceforge.net/apps/mediawiki/tianocore/index.php?title=BeagleBoardPkg. It's an interesting proposition for UEFI-on-ARM research and the likes. 

As for the next article, I'm still looking for a suitable EFI Option ROM to work with. My previous candidates didn't live-up to expectation as they were quite unworkable given the free time I have to work on the article. 

Stay tuned.
