- Add a Pandoc defaults file - Add a Pandoc template based on the default one - Add chapter headers to each section ### Usage To use, install Pandoc and ConTeXt, then simply run `pandoc -d ./pandoc.yaml` from the repo root. ### Maintenance When new chapters get added, the `pandoc.yaml` will need to be updated to include each new chapter's markdown file(s). ### Miscellaneous Notes - The PDF generated complies with PDF/A 1b:2005 by default. - The PDF also contains the source markdown files as attachments - All links are fully functional! - Includes a table of contents! With links to each section! ### Conclusion Enjoy! |

32-bit: Enter
Concepts you may want to Google beforehand: interrupts, pipelining
Goal: Enter 32-bit protected mode and test our code from previous lessons
To jump into 32-bit mode:
- Disable interrupts
- Load our GDT
- Set a bit on the CPU control register
cr0 - Flush the CPU pipeline by issuing a carefully crafted far jump
- Update all the segment registers
- Update the stack
- Call to a well-known label which contains the first useful code in 32 bits
We will encapsulate this process on the file 32bit-switch.asm. Open it
and take a look at the code.
After entering 32-bit mode, we will call BEGIN_PM which is the entry point
for our actual useful code (e.g. kernel code, etc). You can read the code
at 32bit-main.asm. Compile and run this last file and you will see the two
messages on the screen.
Congratulations! Our next step will be to write a simple kernel
