System Guide
Section 2
References to the BDOS size being 1100h bytes are incorrect.
The BDOS code segment is 1000h bytes, and the BDOS data
segment is 00BFh bytes. With the standard distibution,
BDOSH.REL and BDOSL.REL will link these in a separate area
from the BDOS code segment. OEMs that purchase the source
can set an assembly-time switch that will make the data areas
part of the code segment so that it will all be linked as one
segment of 1100h bytes if the BDOS will execute in RAM.
