- Well, there's nothing wrong about absolute addressing. Every C compiler
- generates absolute addressing as well. But of course the linker generates
- a relocation table that enables LoadSeg() to load the program to arbitrary
- addresses.

- Not sure about the 1.3 manual, but read the 2.0 hardware manual page 9ff.

-
- No. Most problems arise from the fact that people did _learn_ programming
- from the hardware manual which is out of scope of the book. It is a
- reference manual, nothing else.

- 99% of all demos do not run on my machine unless I take some precautions
- (like disabling the harddrive, turn off CPU caches, degrader). It is nearly
- impossible to even start a demo from a running system not speaking of returning
- safely to an OS environment.
- Fortunately most demos can't harm my data as they will fail rather soon
- when trying to patch the interrupt vectors in lower memory :)
