WIN CE KERNEL SPACE

MY QUESTION WHETHER NK.EXE RUNS IN KERNEL SPACE OR USER SPACE.SINCE ONLY 32
PROCESS ARE POSSIBLE TO RUN AT A TIME ,THERE ARE ONLY 33 SLOTS OF WHICH SLOT
0 IS BEING USED BY ACTIVE PROCESS AND SLOT 1 FOR ROM BASED DLLS.BUT ONLY 31
SLOTS ARE REMAINING HOW COME 32 PROCESS RUN AT A TIME??

nk.exe is a process. CE needs processes just to be alive eg.
device.exe.
so practically the number of processes you can use us lower. Windows
Mobile I think it's only 21 or so.

There are infact 128 slots in a CE 5.0 system; NK.EXE runs in kernel
mode in slot 97, the other processes in slots 2-32, with the current
process using slot 0. For more details see :

The other processes run in user mode, unless you have explicitly built
your platform enabling full kernel mode.

I learnt from microsoft professional that slot 97 is pseudo NK.exe slot .you
can even watch video tutorials under the topic of win ce memory architecture

1) do not use all CAPS it is considered "shouting" and rude and is harder to
read.

NK.EXE was moved out of slot 1 into the kernel address space above
0x80000000 to make room for the ROM Dlls in slot1 and therefore does not
take up a process slot.
