I received some motherboards without bios chips on them.
Are they dead without them?
Which bios chip is used in a supermicro p4dl6 mb?
Which bios chip is used in a supermicro p4dp6 mb?
Thanks in advance.
		
		
	 
Measure the voltage at the corner pin. It should be either +5V or
3.3V.
The following pages suggest that the BIOS chip is a 4Mbit Flash
EEPROM:

Once you have the voltage, capacity and package style, then it
shouldn't be too hard to find a compatible part.
For example, the flash utility, phlash.exe, has a list of supported
parts which can be displayed by typing ...
phlash /dev
Look for those chips with a "part size" of 512.
These are what I managed to find:
