The BIOS image is for a 512K chip, the Winbond W27C257 has 256K, so it´cannot be used here.

As for the capacitors: For the ones with a polarity (+) marker (like C2) you can use 10µF - 22µF 16V or 25V.
Some of them - like C32 - were never populated. You need to check where there are remnants of wires in the solderings and only replace these ones.

The ones without polarity (like C1) are ceramic capacitors. Maybe someone who has the same board can tell you the exact values (they are in the nF /pF range).

As for the bios my mistake it is W27E512-70

As for the caps - yes i assume you are correct, but i am a perfectionist, i want to know for sure!

C32 was populated for sure i see the legs cutted and there is proof of a similar board:

If you´re a perfectionist you don´t care what PC-Cheapo-Chips did and replace all electrolytics by 22µF 25V tantalum capacitors.
These caps are for filtering out high frequency interferences and soften transients. The higher the capacity and the lower the inductance and ESR the better. The latter is negatively correlated with nominal voltage.
