Ralph Brown has comprised a thorough collection of x86 BIOS Interrupts and their functions. This list is nothing new, but I thought it should high-lighted in this forum.

Documents and links for RBIL can be found at HERE.

If you're new to 16 bit dos assembly than I highly recommend Adam's Assembly Tutorials which cover the basics from the first baby steps to advanced demos in 9 easy to read tutorials.

I've been using the Ketman Interpreter which is fully functional except for saving files in the free/demo version.

A picture is worth a thousand words and being able to watch what's happening in the registers and memory as you mess around makes life a lot easier for a newbie.
