Was reading around the blog posts and they are fantastic! I am really looking forward to the guide about the working of the bootloader, because that's what seems arcane to me right now. I'm really waiting and checking your page everyday!

@sntdevco Thanks! I'm currently busy writing new posts about async/await and threading, so I probably won't have the time for the bootloader post in the near future. But it is on my list and I try my best to write it soon.

So I am new to rust and wanted to take a crash course and this wonderful blog is perfect. Everything up to this point has been working flawlessly until trying to add the lib breakpoint test demonstrated in CPU Exceptions. Once I added the test to the lib.rs and ran "cargo test --lib" I got this error:

Running: qemu-system-x86_64 -drive format=raw,file=C:\Users\Chris_Odom\git\rust\ml_os\target\x86_64-ml_os\debug\deps\bootimage-ml_os-19a3f9364b8c2c6e.bin -no-reboot -device isa-debug-exit,iobase=0xf4,iosize=0x04 -serial stdio -display none
Running 3 tests
ml_os::interrupts::test_breakpoint_exception... error: test failed, to rerun pass --lib

Caused by:
process didn't exit successfully: bootimage runner C:\Users\Chris_Odom\git\rust\ml_os\target\x86_64-ml_os\debug\deps\ml_os-19a3f9364b8c2c6e (exit code: 1)
note: test exited abnormally; to see the full output pass --nocapture to the harness.

Not really sure where I went wrong but I have fully verified everything with in this blog against my code. Is there something I am missing or is the fact that I am using much newer crates that this execution is no longer valid, thanks.

NM, obviously creating the GDT solves the problem, wish that was mentioned, thanks.
