How do I get a speedy boot of QNX4?

Hi:

The system I am working with demands that our AmPro LB3-486e, running QNX4,
boot up in less than 7 seconds.

Our AmPro board is operating a VGA LCD with touch screen (that’s our
keyboard), a sound card and one of the comm ports. QNX is presently loaded
from a compact flash card.

Where might I find documentation regarding tips for speeding the QNX4 boot
process?

Maybe it is possible to burn QNX4 and our program into a memory device
residing on the AmPro boards address bus. This would provide a faster boot
process since memory would already be loaded; don’t have to get QNX4 and
our program off the compact flash card.


Regards, Clint

Sometimes the booting process has nothing to do with the OS,
but everything to do with the BIOS.
I would start with that for sure.

Does your entire application (including GUI) need to be running within 7 seconds, or just the kernel? If it’s the latter, you may be able to tweek /etc/config/sysinit to get specific programs up and running quickly. I don’t know if it’s possible to speed up Photon’s start up
process.

FWIW,
