I'd like to make a few modifications to dosbox just for fun and came to realise that there's not alot of documentation (suffice to say- none!) available. That's not a big problem > though admittedly somewhat frustrating, so I've got a few questions I'd interested to know.

Where did the DosBox developers find information pertaining to:

- CPU Flags (i.e. for 386, 486 etc)
NB: I'm assuming this is from intel developer manuals or something similar. Linkage?

- CMOS Based Info/Specifications
- Protected Mode
- IPX Protocol
- Dealing with memory allocation.

I've got a long way to go yet on learning this sort of stuff- your help is appreciated..

Thanks
