Hello!
I've got an ADDS PC-I that won't post. Two beeps, then repeated 1 long 3 short. It had an expansion card with RTC/RAM/Serial on it that someone added, my best guess so far is that they were trying to set it up for the extra RAM and messed up the DIP switches.
There are no jumpers, just two sets of DIP switches, SW1 and SW3. SW2 is on the keyboard controller's daughter board rather than on the motherboard itself.
The motherboard says it's a Multitech MPF-V PB8307010, I can't find any info anywhere, even on arvutimuuseum.ee.
Here it is:

Any guesses? Any advice would be appreciated.
