Note that there are virtualization software like Oracle’s VirtualBox that provide experimental EFI support, so this is a great way to see the shell in action and do a few things with custom applications without the need for specific hardware. May be good enough for intro sessions.

For emulation environment, you might look on tianocore.org’s sourceforge instance of their emulation environment. Allows you to walk through it all with no hardware necessary. You can also use debuggers such as windbg per the latest debugger package that is up there

VS 2008 (compiling UEFI FW) here gives also a warning (negative number, blabla) when using this:

UINT32 N = ~0;

I suspect constants with the highest bit set are recognized as signed…
So the cast operator was required for me (or using a signed variable type)

Regards,
Sebastian

Sounds pretty good so far. You might want to have a short lesson on cache-as-RAM as part of memory footprint. You might also want to add something about Super I/O and keyboard / UART setup since that could be useful for debugging (Maybe USB debugging would work, but I haven’t tried that much).

btw — I like swami’s suggestion Now all we need is to finish work on TianoCoreboot [1]. Then we can make use an x86 target with OSS CPU+DRAM init to watch the entire boot process from power on to OS loading. I’m thinking something based off a recent AMD CPU/chipset [2] so that can be purchased easily (Tilapia-based boards are currently @ Fry’s for

I’m a silent reader of your blog..Expecting more posts from you.

My thoughts, you can start with ‘Overview of PC architecture’ in your curriculum.

Tianocore EDK DUET* bootable image can help for x86 based lab trainings.

*DUET: Its a bootable image can be created from EDK build. It can boot as a OS on any legacy BIOS based systems. Using this we can even boot to EFI aware OS on already shipped Legacy BIOS based systems.

Thanks

You can use tianocore.sourceforge.net EDK and EDK2 DUET for UEFI Emulation.

Hi
Did you try looking into Coreboot BIOS?
Thx

Dear Mister Natarajan,

It was an impassioning reading. I am eagerly waiting the second chapter.
