That is a start


do you want to use hardware provisions for multi tasking such as TSS
or do it via software?

E-mean,


Well I use hardware task management.... Read the intel specs on TSS and contrary to what you may read you only need one TSS you do not need a TSS entry in the GDT for every single task... As far as switching tasks its as simple as a ljmp to the tss after you have modified its attributes. Just check out the intel docs and use the programable timer to do the task switching just remember you have to reset the  BUSY bits or your computer will fail.
