Simple and minimal x86 OS.

• nasm
• binutils
• mtools

• qemu

Everything is done in the bin folder:

• make - create the kernel binary and diskette image to boot bochs
• make clean - clean all
• make test - clean, build everything and start bochs with the new image

The 'hdimage' file in a MinisFs v2 image, and it is used by the kernel to boot. To edit its contents in linux, issue:

mount -o loop -t minix hdimage FOLDER

To create a new one:

dd if=/dev/zero of=NAME bs=1k count=BLOCK_NR
mkfs.minix -v NAME BLOCK_NR

Currently only MinixFS v2 is supported (that is what the -v flags creates)

• kernel: basic kernel, including mm, interrupt handles, scheduler...
• fs: file system source
• drivers: device drivers (hard disk, serial port, tty, etc.)
• apps: some applications to use with the system
• lib: various generic functions (eg mystrncpy, mystrncmp)
• bin: build system (makefile et al)
• include: system-wide include files (eg. the list interface)
• doc: docs (mainly in spanish)

Every app is in the apps/ folder. These are already compiled and placed in a bin/ folder inside the 'hdimage'. In case you want to change or add any:

• Modify apps/ and call make.
• Add the .pso (these are the excecutables of minios) to the bin/ folder in 'hdimage'
