Hello friends! I am trying to restore an old motherboard - presumably lucky star 386dxa. Several tantalum and ceramic capacitors were missing from the board. I need help from owners of the same board in identifying the capacitor values. I have marked the locations of capacitors with unknown values. I would be glad if someone shared a photo or text with the values ??of these elements. It is also possible that the original BIOS from lucky star 386dxa can be found (on retroweb there are only BIOS from clones of this board). I have restored some printed circuit board tracks

Tnx for correct BIOS! (attached here) and help for TRW Discord members!

So it was needed to resolder chipset, recover caps and CORRECT BIOS (other BIOSes from same chipset motherboards dont work on Lucky Star 386DXA rev. 1.3).
