Еще по 11 CMOS скинуть советуют здесь https://forum.arcadeotaku.com/viewtopic.php?t=22507 I got your PM, put i prefer to answer you here. If the led on the baseboard is always orange, and dont go to green blinking, probably the Baseboard is dead. Try the folowing: 1) Remove both batterys from the Motherboard and from the baseboard. 2) Change jumper switch near to the battery from 1-2 to 2-3 to do a cmos reset. 3) boot lindbergh until you got a cmos error, defaults loaded. 4)Shut down lindbergh and put back batterys. 5) Boot lindbergh again until you got a cmos error, defaults loaded. 6) Power off lindbergh and put back jumper to 1-2. Now reboot and watch the internal led on the baseboard, if the led is always orange, try to change the Baseboard, to another PCI slot on the lindbergh, for example, you can exchange audio card and Baseboard card position. If after all this tests, the Baseboard led is still orange, 100% sure that the Baseboard is dead, 25% of the time is a corrupted flash memory and 75% of the time, the Motorola PowerPC is dead, or needs reballing. If you can get to the test menu screen with the baseboard inserted, you can go to the system information and see if the baseboard appears there, must be detected if the baseboard is correct. Without the baseboard inseted on the lindbergh you should be able to get to the Lindbergh logo screen and then you should be able to use Test Buttons there.
