Got pretty much all of the specs of the missing parts.
Q24 is FDD8796 while Q22 is 1AM (same transistor as Q13,35,36)
CE90 is an 470uF 16v
CE115, CE116 are both poly 560uF 4v
R157 and 155 are both 0 (?) 33 ohm resistors (both have only black on them)
R181 and R187 are 10k resistors
R174 is 4.7k
R4631 is an 0 ohm resistor
XTAL is an 14.318mHz (14.318H0K (or is it an O?))
Capacitor array on NB is 4800pF ceramic cap array.

R157 and R155 might not be jumpers. Some resistor manufacturers stopped marking their parts.

The "1AM" marking on Q22 is an MMBT3904.

Hi

I recently got this HP FMB-0902 mobo that's missing some parts. I need specs of:
Mosfet Q24, Q22,
C202, CE90, CE115, CE116, C204,
R4631, R157, R155, R174, R181, R187,
And a capacitor array on the north bridge,
Thats all the missing components i can see. I know this board is a little too new for this forum, but this is my last hope. Any help regarding those components would be nice.

Ca you post a very clear good picture of the board ? Every one googled can not read the silkscreen (or maybe it just my eyes 🤣).

Thats what I though too. It was weird how the other resistors measured 33 ohms. Luckily wbahnassi measured the same resistors on his board which had 33 ohms. I have looked on TME if they have the "MMBT3904" and I found this one. Is that the correct transistor?

That's the right transistor. It's an extremely common one from multiple manufacturers (some just marked "1A" instead of "1AM").

I've found these XTAL's cause no idea why but the 14.31818mHz THT XTAL's dissapeared in TME. Will they be okay as a replacement for the original 14.318H0K XTAL?

So after replacing all the misssing parts the board is, frankly, dead. A5 post code and 5 beeps (memory issue). The board also doesn't power on automatically when holding down on SB. The beeps are also weird-ish (not what I'm used to from hp desktops). Now I have no idea if its the cpu (heard an pop sound while trying to get an cap back in place), some part which I've resoldered wrong, lose joint(s) or other...
