My slocket8 P3B-F system is also still going strong! I also run two p3b-bf 's with your awesome bios. Thanks a lot for your work @DenizOezmen. Any chance you would create a modded bios for p2b-ds ? Great! :-) I'l probably not be starting a mod on a completely different build any time soon. Have you …

It's really great that you made such a BIOS upgrade for all my BX and VIA motherboards from ASUS. Is there any chance that you would create a similar upgrade for MSI (BX Master) or SOYO (SY-6BA+ IV / +100) boards in the future? Well, I'm not ruling it out. ;-) It's pretty time-consuming, however. …

The wire soldered onto the back of the slotket looks like part of a Tualatin mod. (It probably had to be modded to be used on the Dell board as well.) As for the voltage: VRM 8.5 (Tualatin onwards) retained partial backwards compatibility to previous VRMs. A VID pin for 25 mV signaling was added, …

Actuelly i had the time for a test. The CUV4X-D works fine with the Tualatins. Thank you! Did you do anything else besides the microcode update? Which I don't notice at first glance. Excellent, thanks! The mod contains the changes listed in the first post, as far as applicable/needed for this build …

I didn't expect you to be so quick. I will check it the next days. Thank! There are likely bugs in the first build. Here's a hopefully fixed version.

Thanks for all the feedback! Could ist possible, that you can modifying an ASUS CUV4X-D Bios the same way, with the features which you added to the others? I'll give it a try. Since it's a dual CPU board, it works a bit differently in parts, so no guarantee. I'll get back to you as soon as I have a …

Well if it can't be solved it's no big deal for me at this point. The system is completely usable with the ACPI tables removed. The shutdown bug is nothing more than a mild annoyance. Good to know. Currently, I wouldn't know what to do except for inserting debug outputs at various places and …

Sorry for the absence. Glad to see that others chimed in and helped, though. To get this thread back on track - I can report there is no observable difference between p3bf_no_acpi_tables and p3bf_no_ACPI_tables_no_A0_A1_handlers. Both builds allow Win2k setup and Acronis True Image 2011 to load …

Yes, I remember! IIRC, ASUS BIOS for P2L97 lx2i0102.zip worked with PPRO, no shutdown problem. https://www.elhvb.com/mobokive/Archive/Asus/slot1/440lx/p2l97/index.html More modern BIOS-es for this board - no PPRo support.

Truth is, the shutdown thing isn't really my concern. My concern with ACPI is that neither WinXP nor Win2k will even install without forcing a non-ACPI HAL. They just hang in the installers. Most live linux CDs won't boot either, notably including Acronis true image 2011 which usually works on …

Interesting, do you know if it would be possible to enable a hidden setting in the BIOS to disable ACPI outright perhaps? There are no interesting hidden menu items as far as I can tell. Maybe it's possible to neuter ACPI by removing the ACPI tables module. The test build below does that. The …

I've been using this BIOS for a few weeks now. It works great with one problem - the ACPI implementation seems totally broken. The only way I can get Windows XP or 2000 to install is to use F5 and choose "Standard PC" during the setup. Booting from Hiren's mini XP works, but if you try to shut down …

I made the modification to the CPU 14 years ago for an i815 chipset. The bridged PINs are different from the pictures found on the net for the BX chipset. I will put the Tualatin back into the i815 board and run the CUBX with a Coppermine. I'm very sorry for the trouble! I haven't worked with S370 …
