Multitasking using TSS.

I'm trying to multitask using the TSS feature on the x86 and I'm using the timer int to execute the tasks as the timer interupt the CPU.

But... I can successfully task switch without a hitch but the default operation type changes to 16 bit (from 32... duh. :) And even though the task switch was clean and ints are switched on the timer int won't re-interupt (I've sent EOI)

I am using ring 1 for the task.

Any ideas anyone?

Thanks in advance.

Worked it out.

Anyone needing help on PMode can ask me now ;)

He he he...

So what happened wrong?

Was it something with using 286/16-bit type selectors? "Information has a tendency to be free. Which means someone will always tell you something you don't want to know."
