hi 😀
here's my problem.
I'm currently using a 486 dx4 that i found in an old basement.

suprisingly well protected, that thing survived all those years waiting down there.
at first i did had some troubles since i wasnt aware about those Dallas real time clock stuff. (thanks for all info in these forums)
i changed it and everything is going fine without having to do much.

recently i found a 5-1/4 floppy drive. having only a 3.5" drive, i was pretty happy to have the other size. (still have some games here)
BUT ....i just noticed that the bios is not saving my floppy 5-1/4 drive infos....it always get back at 3.5" for A:
even if i put the drive on B: it still erase the setup back to main previous one.

so now .. without plans and some jumpers everywhere on the mobo.. i was a bit in a pinch to guess and try
and i finally found the plans online ! (what a LUCK)

but despite trying with better infos.. it still wont save. Could it be my Dallas real time not saving ?
anyway. if somebody has a better information about what i could try or should do. here is the webpage to check my Mobo

both floppy drives were tested in another pc and worked fine. so its working. but only 3.5" is working in A: for 486 strangely

Any help is welcome 😀 and thanks to everyone taking the time to answer.
