Funny how this question has come up again. You might like to check the list archive for the previous discussion.
To start this you will need to learn:
X86 assembler - Get a good general purpose book without too many references to any operating system.
GAS The GNU assembler. It comes with it's own documentation.
Writing assembler in LINUX. See the Assembly-HOWTO that comes with all linux distros (ie look in /usr/doc/HOWTO).
The simplest way to test a few assembler instructions is to use the assembler in-line capabilities of gcc . Forget anything you learnt about DOS software interrupts.
There nothing wrong with staying with DOS until you feel confident with assembler. At least it is simple. Linux is good as a host platform if you want to write assembler for what is known as a embedded target.
