I suspect you're thinking of memory I/O addresses and such. One book that
I found good for describing memory I/O addresses\ports is Frank Van
Gilluwe's "The Undocumented PC". Costs about $45.00-$50.00 (US) but it's
a keeper. Hope that helps. Good luck!

Video memory starts at B000H:0000H for monochrome adapters, and B800H:0000H
for colour adapters.

Yes, but only for textmode.
The graphical screens start at location &HA000:0000

Hi all,
I've been wondering that how do you guys get to know what is the
address of a particular memory location. Is there some sort of guide out
there that tells the hex-codes for these. I know for Video memory b2000,
Bios data 64 but that's all I know. I would like to know about others
too...... Thanks for your help..
