I have a couple of questions about TSR's and VGA programming.

First, how do TSR's work in MS-DOS?  Are they simply large interrupt
handlers, since DOS can't do true multitasking?  How do I make sure that
it remains resident?

I'm interested in writing a screen saver, and I need to know how to "swap
out" the current screen, no matter what mode it's in.

Finally, can anyone recommend any good books on VGA/SVGA programming?

Gracias very much...
