I try to understand the code for dosbox. Are there any good books/articles/web that fully describe dosbox internals?
Say write_phyb, what is its purpose and what other impacts does this function bring to other parts of the code base?
thanks

The code is self explanatory of course, if not there's a comment line around it.
Everything for which the above is wrong is either intentionally obfuscated,
unintentionally obfuscated or just sitting there waiting for somebody to place
a useful comment next to it.

Assuming you mean phys_writeb rather than write_phyb then it WRITEs a Byte to the emulated PHYSical memory.
