So I got this machine with 6381 motherboard.

https://theretroweb.com/motherboards/s/ibm-ps … 81-433dx-466dx2

But it's missing oscillator from position Y2, near the rtc section of the motherboard.
Does anyone know the value of the missing part?
At current state machine does not boot, it gives one beep following three beeps and then two more.

Could be the standard 32.768 kHz crystal used for the rtc clock; there is a Dallas clock chip nearby I think.
