Subject: [Freedos-kernel] FAT information in FreeDOS-- where to look?
Reply-To: [email protected]
Hi everyone,
I have a school project that involves a small OS we're writing. I'm on the
team that has to implement a FAT-like file system. I've heard that FreeDOS
has an implementation of FAT, and I'd like to look over the relevant parts
of the code, so I have some idea on what needs to happen. (right now I have
no clue on implementing FAT)
Could someone guide me as to what I should do? Meaning, source files to
grab and where to start looking through them and what to pay special
attention to? I'd be in your debt too if you knew of any good documentation
on the web that might be of use. Thanks very much.
-Jim

[dev kernel, will check stable shortly]
It was brought to my attention by Eric that in config.sys read() returns
an unsigned count or 0xFFFF on error but we were checking as though it
returned a signed value (-1 or less than requested count). I committed
the change that makes these tests check instead for != requested count
(ie less than requested count or 0xFFFF; also greater than requested
count is an error, but can only be seen if the kernel is already corrupted).
I also committed some code lying around in my tree, it is very simple
code that allows DebugPrintfs to be sent to a COM port (hard coded as to
which one, so a recompile is needed if you want to use another one).
Note really the most robust stuff, but works well for debugging apps
that don't mess with the serial ports. All conditional, so won't show
up unles explicitly requested, also I think its OW only.

Debugging the executions of programs and how to work on the kernel and
freecom on a .TXT file on hard disk or similar will be good :) Using the
debug option in the SYS CONFIG :)
I am waiting for the latets version of freedos with win31support enabled
and 80x86 code by default :)
Thanks
