mini operating system

["azeem ahmad" <azeem81 msn com>]

hi list
i want to develop a basic operating system for learning purposes which 
contains the following

-device manager
-File manager
-memory manager
-communication manager
-bootloader

all these things i want to develop by my own self, i want the system to 
reside on a flopy disk, with which i cant boot an Intel computer and can do 
some basic work.

the problem is that i cant get so many floppy disks to work and test again 
and again as floppy disk demages so quickly.

is there any simulator on Linux or windows which i can use to check my 
programs. (note that these programs can not be checked on a running 
operating system, as i have to initiate BIOS interupts directly).
the Operating environemnt i would prefer is Fedora Core and the Language is 
ANCI C.

waiting for ur response

Regards
Azeem
