Hello,
Well the good news has finally come, I've got fat16 write support and my fat driver is complete with the exception if rmdir (Remove Directory) which should be implemented by today, FASM doesn't need it, so leave that for now.
Well I just want to discuss with you guys if there are any changes needed.
ZICRONIX FILE ACCESS
In the operating system the root directory contains the kernel, ramdisk, and other modules
like fonts, drivers etc. and are totally inaccessible to the applications and the user. The directory /usr is set to default and contains the user files. The one and only environment variable is usr/bin which is meant for executables of applications. Hence an absolute file name is something like:

You can set EAX to this variable and call chdir.
However for example if the programming was executed from another directory (not from usr)
then the current directory in the above format is passed in EDI.
You can tell chdir to switch to local directories if you know that you're in your required parent directory by:

Remember that the arguments passed by the shell are capital letters!
Commands supported:
mkfile - Creates a file in the present directory (DOES NOT SUPPORT, pathnames)
rmfile - Removes a file (same as mkfile)
mkdir - Creates a Directory, same as mkfile
chdir - Switches to a directory
load file - Loads a file, (If pathname is given good, if not searches in the present directory
write file - Writes to a file (Sames as loadfile)
lseek - Same as UNIX
prints - Prints a string! No formatting
itoa32 - 32 bit integer to string
atoi32 - String to 32 bit integer
getmem - Get all usable RAM on system.
malloc - Allocate Memory (Does basically nothing, simply increments memory space, passes
EAX)
So am I ready for the port? Hope so.
Plus FASMARM has the same dependencies as FASM right?

Yes.

Almost there, getting #GP for no reason
