Hi

I have an older Dell Pentium II 350mhz computer with me. I recently got a
400 PII for free. as my computer manual said that I could go till 450 I
plonked the new cpu in.

But my system still shows it as a PII 350. is there anyway, i can change the
settings so that my system reconizes it. I tried thru the normal bios but
there no such thing there. i just read that I need to go into maintenance
mode. As i don't have much info on this, I am afraid to blow it up

I would be thankful if someone can help me with my problem. Also when i
check the system properties in windows, it shows my older cpu as a PII
having stepping 2 while if i put the new one it shows step 1. I can't seem
to make head - or - tail out of it.

Thankyou in advance to anyone who can help me solve these problems.

you need to change the frequency and multiplier jumpers

that info should be in your motherboard manual

if not...just get a flashlight and some reading glasses
and you will see that the info is marked right on the motherboard

just make a selection that adds up to 450mhz

just as an example 75mhz X 6 =450

You ought to try updating the BIOS. Most likely this is a cosmetic
problem, that the motherboard simply doesn't know what to call the new
CPU. Intel PII at 350MHz and above are all multiplier-locked (except
for very rare engineering samples) so there should be no multiplier
changes needed. What you might do is boot to maintenance mode (or
whatever it's called, I forget the exact terminology) where you move a
jumper, boot the system to a special bios menu, save the settings,
power off then return the jumper to normal position. I don't recall
the exact jumper position either but it should definitely be in the
motherboard manual, is on the lower-right quadrant of the board, IIRC.

You can also run a simple utility that will report the CPU speed and
more, WCPUID:

Umm, crap. The PII 400 is designed to run on a 100MHz FSB and the multiplier
is internally locked at 4x.

There is probably a set of switches or jumpers. They will be limited to 66
or 100MHz FSB and the multiplier switches/jumpers will probably only go as
high as 4.5x.. This is a Dell we're talking about here.

I doubt it's set in BIOS but it could be.

yes, of course .

i was looking at the part where he said the board could
take up to a 450cpu...i missed the 400mhz cpu part...
