A few minor issues in chapter 2 #18

arun-mani-j commented 1 month ago

Hii, thanks for stepping up to keep the project alive.

I'm tried the chapter 2 and found some issues regarding the packages one needs to install.

  1. In "Quick Setup", one also needs to install mtools, otherwise they will get - grub-mkrescue: error:mformatinvocation failed. Also grub-pc-bin does not seem to be required anymore.
  2. In "Running Bochs", it should be sdl2 over sdl.

I'm on Debian Testing edition, so there is very good chance that future editions of Ubuntu and other Debian based distros will have to reflect it too. I'm not sure how it is on other distros like Fedora or Arch.

I can make a pull request if you like.

Side note:

  1. I'm getting bx_dbg_read_linear: physical memory read error (phy=0x0000322f3331, lin=0x00000000322f3331) Next at t=662802 after pressing c after running bochs. And my registers are all 0, what could I be doing wrong?
  2. Can you open Discussions in this repository so people can use it for help instead of spamming the issues. :see_no_evil:

Thank you!

Howdy! I've opened up Discussions, that was a good idea. I've been pretty busy lately, and have not had too much time to ensure that everything is working for the book here, so I appreciate the comments. I'll look into your suggestions, but it would definitely speed things up if you opened up a PR yourself. Going back over the dependencies is something that's on my list of things to do, there have been a lot of things that need to be updated, including potentially adding some sections on UEFI.

For your side note, I can't think of a particular reason that might be happening, but feel free to open a discussion. It might be useful to include your code as well. I may or may not be able to spot the problem.

Thanks a lot! Let me get the PR ready.

Wish I could help on UEFI, but me myself a beginner in these things, but if you have any extra resources and kind of plan, perhaps I could try my best :)

OrdoFlammae commented 3 weeks ago

Yeah, even I am not amazingly familiar with UEFI, so unless someone from the community wants to step up and add large sections to the book, that's most likely a project that will have to wait for some time, until I have a chance to learn all the different details and distill them into something that fits within this book (or potentially a separate work).

For your PR, I would like to get your issue resolved first, as I am still uncertain whether or not it is actually functional until a full working example is produced.

Thanks. My PR is regarding the missing packages, so don't think it has anything to do with the issue I'm facing. Regarding working example, I'm able to reproduce the issue as it is from the code sample on the book. However, if you prefer, let me upload the files as a zip too in the discussions :)
