I'm in a graduate level OS course this semester and we are using an embedded OS called XINU. It runs on Linksys routers and has both MIPS and x86 ports.

The class format is that we are given a basic OS framework and then have to add functionality on top of it. I really like it, since I have tried several times to write my own OS but always get hung up on the lower level details. We've finished a Pipe API and remote file systems. Currently, we're working on adding filesystems.

I was just wondering if anyone here has ever or does use it?

Hi samoz,
I did read the text book , Operating Systems - The XINU Approach by Douglas Cormer. It was not availblable in India. I had to order using Amazon . Is that the OS you are talking about ?

It is. I have both an old copy of the PDP version of that text as well as the newer one which uses Linksys routers.

What did you think?

Hi,
I have a relatively old version for PC . It uses bios and is made on top of dos . But it is a good read and easy to understand:) . See : ftp://ftp.cs.purdue.edu/pub/Xinu/ to get the source code . PC Xinu is more or less monolithic in nature.
