Good afternoon, there was a problem with the machine. Immediately after booting the system it automatically shut down and rebooted. Due to this suspicion that HDD was dying, it was decided to remove it and check it. After removing the HDD, the BIOS battery was also replaced. The check showed that it was working, but immediately after the check the system stopped seeing the HDD. Separately it is still detected on the computer. There is a suspicion that something is wrong with the EXM-HD board, which is an adapter from IDE to EXIM, because again there is a suspicion that it was tried to run from the PCI-slot of the computer's motherboard. The manufacturer of this board claims that it is electrically compatible with the EXM ISO, but having looked at their pinout, I can safely say that the compatibility is not there. Do you have any experience with EXM modules? Or is there a suspicion that enabling HDD kills the bootloader and loses the system disc configuration. Because the machine doesn't want to see that it has an HDD installed at all.
I have entered the correct parameters in the EXM configuration, nothing helps, yesterday I was sent a backup HDD from another DMU60T, but the machine gives the same error "failed fixed disk".
Can you please tell me what else could be the problem?
Best regards
