    RTC problem on MVS

    Hi, I have a uncommon problem with this function.
    Quartz 32,768 Khz is ok, 4990 also, I test with another one chip. I swapped also the NEO-F0, the problem is similar.
    when I access to the RTC screen with Diagnostioc bios there is a random reset which occurs (most quickly with higher frequency but the reset doesn't reach the same value).
    In which chip the watchdog function is done ?

    edit: with unibios, black screen. With OEM EPROM "Calendar error" message.

    it's a 1st gen, A0-B0-C0.
    FVRAM are the same that my others slot.
    other selftest are ok.

    edit: what do you call Even signal on neo-B1 ?
