Hi,
I was realy serious about writting small OS, or rater environmnet+GUI basing
on DJGPP... I got my first job (as programmer of course :) so I didn't have
much time and this is why UPT still isn't ready...

I have on 2 questions...
1) I realy want to call other exe functions, but we had discuss it before,
and I understand that this is hard to implement... so maybe - can You give
me adress of DXE examples / FAQ / documentation ?

2) Multitasking... currenty I'm using alarm() to prevent system hangs... but
I don't now how to implement or sikmulate multitasking... if I can only now
adress (processor state as in longjump) of instruction that was
about to execute when sigalrm was rised... I could then jump to task #2 and
then jump back to instruction that was terminated by SIGALRM...
why SIGALRM has only 1 sec resolution ? Can I rise some signals in regular
time spaces less then 1 sec ?
How about using 1C clock hardware interrupt ?
Can I implement something even more precission ?

Please help me.... if You have some time ofcourse,
many thanks :-)
