help me !!!Routeros 5.x Booting power off !!!

hello,
My device routeros 5.x start automatically during the phenomenon of auto power off, replace the card and re-install, but also replacement of the other hardware does not work, and start using the 3.30 or 4.17 is normal, but because these versions do not support the intel 82574l , so there is no way to use, please try to help me solve my customers need more than 1,000 such devices, thank you

use 256m cf /512m cf /sata 512m dom

Generally the first and second times the normal, automatic power off when there again after restart can not be normal.

please help me ,help me!!!
thank you.

Some things to look for:

WOL (Wake on LAN) and other similar functions are usually set in the BIOS. Make sure they are turned off.

Watchdog timer - try turning it off if there is one.

Power up after power failure (and restore) - also a BIOS setting

Just some ideas. Good luck,

Tom
