But, you probably guessed it already: Changes have no effect. So close after so many years, very annoying. Thanks for testing! Yes, unfortunately, that was kind of expected. Should you happen to find something like unpopulated solder pads labeled "JEN" (or similar) on the board, chances might be …

Hi everybody! This may be my last hope... I did rebuild my system from 21 years ago. The board is a CUV4X-CME running with a pinmodded SL6BY Tualatin. Everything went fine so far. One of the last things i wanted to do was unlocking some functions in the BIOS (FSB is grayed out, VCore not even …

I am really trying hard to find microcodes for Intel Pentium III late coppermine (like my SL5QW) and tualatin, with no luck. Microcodes are still available from Intel . SL5QW has a CPUID of 068A, so you'll need the file intel-ucode\06-08-0a. (The first 2048 bytes are enough; the rest of the file …

I successfully tested the three files quoted with a Lin-Lin + Tualatin Celeron 1400 on CUBX and CUBX-L and with a Pentium II 450 on the P3B-F. (Something seems to be wrong with my Upgradeware SLOT-T + Tualatin Celeron 1400 on it. I'll check this later.) . The speed of a Noctua NF-8A slowed down to …

I confirm the other C3 doesn't work, the cpu id code is slightly different 800 mhz is 698, while 1,2 ghz is 69A, the issue could be that the slower one is an hybrid, in fact I can't find any info about a nehemiah rated for 800 mhz anywhere else: https://imgur.com/a/RxtyAnC C3s seem to be kind of …

It's a huge success! Progress! :-) Regarding the results: The cache display is indeed a visual bug. It should be possible to add the 133 MHz options, but that's something for another day. ;-) I don't know enough yet about the CPU temperature readings. I guess they are done through the HW monitor …

I just found this: It seems some boards have issues with cache initialization for Nehemiah CPUs. I was able to boot a C3 Nehemiah 1.2AGHz on my ASUS CUV4X out of box, but the board recognized it as "Pentium II 1200MHz" with no cache memory (Cache Memory: None). Without the cache memory the …

I just tried the newest bios, nothing changed. Recognized as Pentium II and the same error as before. Now that is confusing. Could you post a CPU-Z report in .txt format? That should contain the results for the various CPUID levels. Edit: I guess I spotted a bug. Could you try the new version? [ …

I also tested the via C3 cpus I have (just 2 unlucky: a C3 800 rated for v1.25 800 mhz which seems a Nehemiah cpu despite it should start from 1ghz and the 1.2 ghz cpu v1.45): The first one isn't detected, debug card shows …

Thanks very much! I will report back... Back in the day, people used to blast fans at ridiculous speeds.... You can still buy pretty large Socket 370 heatsinks, so why run a sleeve bearing 40mm fan at 4000RPM when you can buy a good ball-bearing fan and run it slow? Thanks! I guess you would only …

Yes, you are correct! (and may I say a real wizard too - at that). It's this fan, and indeed it is a 1200RPM fan. Thanks for the confirmation!

Would you be able to modify the subroutine in the hardware monitor that detects the fan speed to support reading sub 2000 RPM? This problem is not unique to this particular BIOS. Many if not all early Award BIOS have this problem...or at least with the fans I've tried it with so far. This is for …
