i have an asus p4g533-la mb which was an oem for hp as an echo4 motherboard.
when i put a celeron 2400 in it, it boots to the hp screen and then it
continuously beeps and locks up. board is supposed to be for both p4 and
celeron. any ideas. thanks
Intel has blessed us with way too many flavors of processors.
Maybe you have a Celeron D, and the BIOS and Vcore supply cannot
handle it ? Some of the older motherboards are effectively
restricted to Northwood processors (0.13u) and to the lower
FSB values. Newer Prescott (90nm) processors are a problem.
You can look up your processor via the SSPEC (SLxxx code on the
box somewhere), or the longer order code - see processorfinder.intel.com
..
The Intel pricelist is here, and shows you how much product is
currently shipping as Northwood (0.13u) or Prescott (90nm).
Buying a 0.13u processor is more likely to work.

Does HP have a support phone number ? Maybe they can tell you
exactly what works. Or, if you know of a particular Asus retail
motherboard that matches the design of your board, you can
check the cpusupport web page for that board, and "proceed
by analogy".
(P4G533-LA BIOS upgrade - download and see if it has any release
notes as to what it fixes.)

I found a picture of the P4G533-LA and it bears a striking
resemblance to P4GE-VM (see page 13) -

So, go here and look up P4GE-VM, to see what processors will work.
There are no Prescotts or Celeron D processors listed there:
