Re: [Freedos-user] Can you help me?
There are a few books on the i8088 and i8086 chips out there and a few books on DOS assembler: unfortunately my personal library's boxed up at present so I can't quote titles. But the DOS memory model/s are based on the various Intel chips from i8088 right up to i80386; it'd be easiest to get your head around the i8086 for starters.

Getting back to the original question: how to start learning the FreeDOS kernel. I'd recommend buying a copy of 'The FreeDOS Kernel' by Pat Villani. It's a bit old by now, and much of the kernel code has been updated since this was written, but it is still applicable and gives a very good high level overview of the FreeDOS kernel. Just don't get too bogged down in the technical details of the book; they may have changed in the current version of the kernel. I'll assume that you know C programming, and have at least a working knowledge of assembly. You won't be able to contribute to the kernel if you don't have these skills. FreeDOS is a free operating system that is made up of 3 basic layers: 1. A core component (the kernel) which runs DOS applications 2. A command interpreter (command.com, aka FreeCOM) that takes your typed commands and runs the appropriate DOS program 3. set of DOS utilities (such as CHOICE or EDIT or ATTRIB) that do small tasks, or assist in batch programming On top of that, you have DOS applications, which can be written by anyone - such as games or word processors or spreadsheets. I don't know your background (you didn't say) but if you haven't done much C programming or assembly, working on the kernel will be challenging. You may have an easier time with the DOS utilities and making some improvements there. -jh -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Otherwise, the only real way to get familiar with the kernel is probably just to build it yourself and poke around.
