ManRiX
THE DESIGN OF ROBUST AND EFFICIENT MICROKERNEL

You should have grub as bootloader. Grub bootloader loads the ManRiX.
Download, unzip both the codes(manrix.tar.gz) and Images(manrix.img.gz).
To Create a bootable floppy,
Unzip the manrix.img.gz;
Write to floppy:
In **ix cat manrix.img > /dev/fd0.
In Windows get the program rawwrite
(http://uranus.it.swin.edu.au/~jn/linux) to write to floppy.

First open the grub.conf file.Add the following line on the grub

title ManRiX OS. (i am assuming you are not using LVM).
root (hd0,6) # replace this with whatever on Linux entries.
kernel /sys/kern
module /sys/conmngr
module /sys/fsiomngr 7 ;
module /bin/init
module /sys/misciomngr
module /bin/ls
NOTE: the fsiomngr service requires a parameter which must be ext2/3
partiton and will be mounted as root. 6 will be same as hda7 in linux,
(hd0,6) in grub.

This kind of Design is ideal for Real Time Operating Systems, but we are using this also for Desktop Systems. The Real Time Capabilities are not Added Yet but will be added gradually.

ManRiX till now support ANSI and POSIX interface. We have reuse glibc library according to our ManRiX design if possible.Otherwise we have written on our own.

Till now ManRiX support 63 system call
