Hi, I'm rebuilding the first generation Pentium 4 system. luckly I just spent $10 to get an ASUS p4t-e motherboard. Of course, this motherboard was marked as no POST, but when I got it, I realized that the PWM IC of CPU had been disassembled for repairing, but the work seem not completed and leaving several blank positions. I don't know the accurate spec of the six missing PWM ICs. If anyone happen to have this motherboard, I hope you can help check the BOM:

Q14 appears to be a 50N03 or 60N03 (whichever will work, one is 50A and the other is a 60A) according to this pic I found on Imgur

Q12 and Q11 seem to be the same so that leaves you with Q13, Q15 and Q17.
