+The following list of corrections should be made to the Personal CP/M 8-bit
+version 1.0 documentation.

+        BDOS function 2
+                text says 'CONSOLE INPUT'
+                should be 'CONSOLE OUTPUT'
+
+        page 2-45
+        BDOS function 33
+                'Entry Parameters' add after Register C line:
+                'Register DE:   FCB Address'
+
+        page 2-49
+        BDOS function 35
+                replace information about values returned in registers with:
+                'Random record field of FCB set'
+
+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.

+        BIOS function WRITE
+                Entry Parameters:  Register C = 0:  normal sector write
+                                                1:  write to directory sector
+                                                2:  write to the first sector
+                                                    of a new data block
