Terentyev / OS

Very simple OS (for study purposes)

Prepare

Needed packages for test: * app-cdr/cdrtools (>=3.00) * sys-boot/grub (>=0.97-r10) * app-emulation/virtualbox (>=4.0.12)

If your distributive don't have a cdrtools package, you can use use genisoimage (1.1.11), but you should fix ./Makefile:

replace

    MKISO=mkisofs
    #MKISO=genisoimage

to

    #MKISO=mkisofs
    MKISO=genisoimage

Create virtual machine

Prepare VirtualBox machine:

VBoxManage createvm --name vmOS
VBoxManage registervm ~/.VirtualBox/Machines/vmOS/vmOS.vbox
VBoxManage modifyvm vmOS --memory 32 --boot1 dvd
VBoxManage storagectl vmOS --name bootcd --add sata --bootable on

Or you can run:

make create_vm

Create bootloading ISO-image and kernel

Build OS kernel:

make
