Are JamesM's tutorials still being maintained?

I found a number of small issues with them (nothing major, you can see what he meant, besides, the downloadable code is fine),
but I'm not sure if he is still maintaining them. The site gives the notice "Copyright James Molloy 2008 - ", so possibly not.
Anyway, two things I found are:
The lower 5-bits should be constant at 0b0110 - 14 in decimal
should be 0b1110
Code: Select all
idt_set_gate( 0, (u32int)isr0 , 0x08, 0x8E);
idt_set_gate( 1, (u32int)isr1 , 0x08, 0x8E);
...
idt_set_gate(31, (u32int)isr32, 0x08, 0x8E);
the last one should be isr31
If you are around JamesM, I hope you are still maintaining those tutorials, they are a great resource.

JamesM does not maintain it any more. You should see the multitasking part, he tells you to move the stack, and try to overwrite the EBP on the stack which possibly means triple fault.
I asked about it, JamesM sais that he is not bothered to replace the tutorial code with new code from some other place (Google Code I think?)

I was thinking, if he isn't, the tutorial and code should be in the osdev wiki so that when someone finds a typo like those they can just edit it.
I will see what other answers I get, but if he really isn't maintaining them anymore, and I have some time after I finish using them, I will ask his permission to do so. At the very least we should create a page listing the problems, like with brendan's tutorial.

Yes
http://www.osdever.net/bkerndev/Docs/title.htm it says Brandon Friesen, or am I mixing things? I'm sure I saw some time ago a Br* set of tutorials and there was a wiki page listing the problems.

Oh. The similarities between "Brandon" and "Brendan" made me assume you were talking about Brendan. I also assumed Brendan had some tutorials somewhere, since he does know everything.

That is why I used "brendan" the first time. I knew there was a brendan here and I knew there was some br* tutorial so I assumed it was his.

Oh! and I thought both of these names referred to the same person.

They're not being maintained - you're right.
And I haven't got time to maintain them. The updated code (
much better and more concise than the original) is at
http://jamesm-tutorials.googlecode.com .
I never got time to write the accompanying documentation, which is the most time-consuming part of the process.

None, if you give me your google account name.

Done.
