Looks like you need to do allot more homework. 

I am familiar with uC/OS II, but not MULTI-C RTOS. 

Some starting points:-
1) subscribe to the embedded newsgroups
2) seach the internet for embeded projects
3) Goto http://www.embedded.com/
4) Goto your local newsagent and purchase some electronics magazines
that included embdded info, such as :-
	- Circuit Cellar from UK
	- Embedded Systems Programming from US
	- DJ Dobbs from US if it has any embedded articles

I have not seen any ports of uC/OS-II or uCOS to DJGPP and MS-DOS. If
you have one please make it available. Please note that you cannot use
DJGPP witht he MS VC++ uC/OS II port.

If you are uisng an embedded x86 SBC then you will need to obtain the
complete register specs for the GD5465 chip or find a graphics library
that directly uses these registers if you are going to use and
embedded RTOS.

Another choice is to have a look at eCOS, see www.redhat.com and
search for sCOS as it uses GCC as the toolchain.

yet another choice if you do want to use DJGPP is to look for a
kernel.zip or kernel2.zip which is a kernel for DJGPP that allows you
to boot from a floppy without DOS, but is old and has not been updated
for a number of years.

There are allot of graphics libraries out there for DJGPP. Have a look
in the v2tk directory for them. They vary in their abaility and what
they support. There are some that are cross platfrom and as such make
porting apps easier later.
