On MOXA DA-683, QNX booting is somewhat slowly, especially at the stage of scanning for devices of SATA ahci and EIDE. It spends 30 seconds to boot up. Because DA-683 will be used in substation automation system, so the acceptable time should be 10 seconds.
There is another problem. DA-683 has no sound card. During booting, it will display a message:
mount: Can’t mount / (type io-audio)
mount: Possible reason: Invalid argument
So my questions are how to skip starting io-audio, and is there any method to speed up booting?
