The following list of corrections should be made to the Personal CP/M 8-bit version 1.0 documentation. Programmer's Guide page 2-10 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. page 4-15 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
