|
||
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
|
||
|
||
|
||
/README.TOO
|
||
|
||
Please note: line 2528 in BDOS.MAC is corrupted. It should read
|
||
|
||
jp z,COPY$DIRLOC ;stop at end of dir
