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.
