Hi,
I am trying to fix and upgrade a Olivetti Modulo M4 40. It comes with a 25mhz 486 SX onboard. It starts fine with the SX, but when i install a DX2 in the other CPU slot it does not start, well the PSU does and the power led is on, but no beeps or anything.
I have tried a regular Intel DX2, a AMD DX2 and a Intel overdrive DX2. Same result.
I have set the jumpers according to the manual, and tried all other combinations of the CPU selection (not that there is many). Also the 25/33mhz jumper
This is the board: https://stason.org/TULARC/pc/motherboards/O/O … 4XX-BA204X.html
Is the socket broken or something?
