Question about DFI PE21-EL Motherboard
Hi I currently use the DFI PE21-EL motherboard with a 400mhz FSB and am looking to upgrade the cpu. I am currently running a 1.7ghz intel celeron cpu. The website http://www.firingsquad.com/hw/268/DFI_PE21-EL/ says that the mobo supports up to a 2.4ghz Pentium 4 with the 400mhz FSB. However the website http://www.cpu-upgrade.com/mb-DFI/PE21-EL.html says that the mobo will support up to a 2.6ghz pentium 4 with the 400mhz FSB. The DFI website has no information on this mobo anymore.
My questions are these:
-What is the fastest pentium 4 cpu that I can use in my 400mhz FSB mobo?
-If it is in-fact the 2.6 cpu that is the fastest, do I need a driver or BIOS update to do this, and if so where can I find this driver or BIOS update.
-On some mobo's there is a jumper you can switch to change the FSB, does my mobo with the 400mhz fsb have the ability to be switched over to 533mhz FSB?
-Lastly, does anyone have access to the owners manual for this mobo, and if so could I get a copy of it, preferably in digital so there's no mail/shipping involved.
Thank you for your time, it is much appreciated. Please let me know if there is anymore information you need from me.
Merry Christmas and thanks again.
Your motherboard supports 2 different fsb's.
