welcome to the adventure this is Adam and today we're going to be going over a basic setup for
the config dot C's file in order to edit our config sis file will need to open up a program
called edit now I could press ENTER here open the edit program and select the config dot psa's file
that I want to make some changes to but I want to tell ed --it to open that file directly so we can
do that by typing in C colon backslash config dot siz so that will tell it where the file is
and here is the document it is blank on purpose the one I copied from the floppy disk did have a
couple things in it but the purpose of this video is more to go over how to write your own config
sis file so we're gonna start from the top and I just like to have caps on because everything
can be in caps and it usually is so we're going to start with the statement for device think of the
config sis file almost like the device manager in Windows it's able to manage device drivers
for the system so device equals and then we're giving it a path C colon backslash DOS backslash
hime m dot SIDS this should always be first in the config TSA's file it's giving us access to
the high memory area we'll go into a little more detail about memory management in Doss how that
works and what all these different things mean in a later video the next item I would like to
put in here is another device and another path and this one is EMM 386 dot exe this is going to
give us access to extended memory it should be second in the document and there's a parameter
I'm going to use here no EMS we'll explain that a little bit later the third item to put here in
our config sis file of course is another device and another path cd1 dot says this is going to
give us access to the optical drive there is a switch we're going to use here it is B for the
device name followed by what we want the device name to be in this case I'm just going to call
it a BTC which is the manufacturer of the drive that I'm using you can name it anything you want
but that name has to be consistent with what we put in our autoexec.bat file later always
company can fix this file and we'll just add those here really quick that is going to be
files and its default setting is 30 windows 3-1-1 will change this later buffers which
default to 20 and the last drive so this is the highest Drive letter that can be assigned to a
device and by default that is set to Z we were talking about partitioning hard drives and how
logical drives can be added within an extended partition so this is where we're defining the
last Drive letter that will be made available and so that is it for editing the config sis file we
head and save thanks for stopping by please like comment and subscribe see you next video
