Hi everyone! I have received an Elpina M571 motherboard, for Pentium, MMX, Cyrix 6x86, AMD K5/K6 and IDT C6, WinChip.
It came with an IDT C6 and with this processor it works correctly.
I would like to use this board to test processors, because:
The problem is that it has a SMD component soldered between pins X02 and X04 of socket 7.
According to the data sheet of every processor listed at the beginning, those pins are VSS (ground) and BRDY#
I know that people add resistors to reduce voltage to use low-voltage processors (the minimum supported by the board is 2.2V), but these resistors are added near the voltage regulator, not between socket 7 pins.
As I don't know the purpose of this mod, I can't dare to change the actual processor or configuration, because some mods work for a certain configuration and prevent other configurations to work.
Does anybody know what this modification is for? Is it a known hack for Pentium boards?

I would like to use this board to test processors, because:
- It supports almost the full range of Pentium clones.
- It is easy to set the jumpers (they are documented on the board itself).
- I don't need to connect nothing (it has disk connectors, and it has an integrated VGA) but the power supply.
