Crew Antinomy Posted August 2, 2022 Author Crew Posted August 2, 2022 That's interesting. Could you flash my BIOS, take the battery out, clear CMOS and boot without the battery at all? If you're switching from a 1023 to 1024 you should flash the chip completely - not only main section, but the full BIOS. If you do this, please post photo of the boot of your POST screen and Jumperfree section.

Sparks.nl Posted August 3, 2022 Posted August 3, 2022 (edited) That was version 1023. I downloaded it straight from Asus. I don’t remember if there is an option not to wipe the chip completely when flashing it via my usb tool externaly… I wipe first by hand and then flash it. Edited August 3, 2022 by Sparks.nl Quote
Sparks.nl Posted August 3, 2022 Posted August 3, 2022 I will test some more after I binned my DDR2. I just started binning them. That could take a week. Quote
Crew Antinomy Posted December 21, 2023 Author Crew Posted December 21, 2023 (edited) Something new for you! Found out two new strap/divider combinations: 1:1 (100MHz strap) and 1:1 (166MHz strap) FSB 100 1:1 FSB166 1:1 Feel free to play with it. I've updated the benchBIOS to version 1.1. As you can see, PAT works on these dividers with 865PE boards too (checked on P4P800 and P4P800 SE). @Tzk@digitalbath you might be interested in this finding. Digitalbath you might want to add this to your P4P800 SE BIOS. FSB100 is value 0000 and FSB166 is 1101. benchBIOS v1.1.zip Edited December 21, 2023 by Antinomy 6 Quote

I am going to give my SE away. If I find some time, I will look into the BIOS code to understand what you did there. 1 Quote
Sparks.nl Posted December 23, 2023 Posted December 23, 2023 I will make sure I test the bios, but busy now. 1 Quote

I just labeled two dividers in the menu, like I said - values 0000 and 1101. O.K. I'll mod it. I found out that my BIOS works on P4P800/SE only with RAM in slots 1 and 3. With slots 2/4 it stops at POST A4. But I need 2/4 to use RAMbooster in slot 1. 1 Quote
Crew Antinomy Posted April 23 Author Crew Posted April 23 (edited) When you thought everything should be found after 20 years, lol. Another update to you! Change list: 1) Added support for Mobile Pentium 4 Prescott CPUs. EIST is enabled so you can use any MSR utility of choice to change the multiplier (CrystalCPUID, CPUMSR, RMClock, etc.) 2) Added tRAS values 9 and 10 to BIOS setup 3) Fixed help message for Advanced memory settings section 4) Set default system date to 01/01/2024 http://valid.x86.fr/6pmnfz Should work with P4C800-E, P4P800 2.0 and P4P800 SE. Issues are reported with P4C800 (timings are not set). I don't have this board so can't check myself. P4P800 series (-SE too) work with memory in slots 1 and 3 only. benchBIOS v1.2.zip Edited April 23 by Antinomy 8 Quote

How did you implement the mobile microcode ? you have the microcode as a file in hand ? edit Many years ago i was trying (with no luck) to extract the microcode from an Abit bios and implement it to Asus ... but never managed to do it. I always had some kind of checksum mismatch stopping me 😄 Edited April 23 by TASOS Quote

It wasn't about microcodes at all. In fact when we talk about compatibility, it's 95% not the microcodes. 1 Quote

(regarding P4 mobiles working out of the box) ? Quote
Crew Antinomy Posted April 24 Author Crew Posted April 24 No idea, I didn't have any Abit 865/875 boards. The problem with Asus was that it had problems initializing TM2 correctly which only mobile Prescotts seem to have. We have a saying - "Woe from Mind" which kinda explains the situation. Asus had too many checks and it summed up in an exception that crashed them altogether. I bypassed the problem ones and voila. I've used IDA to disassemble the problem parts. 1 Quote

Crew Antinomy Posted April 30 Author Crew Posted April 30 23 hours ago, TASOS said: Why cpuz reports a 865 chipset ? Because it's a P4P800 board using a P4C800-E BIOS. Hence the chipset is 865PE. Quote
grease90s Posted June 30 Posted June 30 awesome i gotta try this on my p4p and p4c boards. Although I'm currently stuck with my p4p tried the bigtoe mod to keep pat which worked but wall at fsb240. cant find the afudos utility to reverse it. stuck with p4p8x boot block unless u know which commands would be helpful. anyway safe to assume ct-479 compatibility is still intact wanna try my ct-479 with your bios. thanks man!

Just saw your message. Versions 1.0 and 1.1 for sure should be completely compatible with CT-479. I did a small change in 1.2 to make P4-M work but it shouldn't affect CT-479 either. Didn't test it though so feel free to give some feedback. As for BIOS flash you need ES-version of AFUDOS that allows you to flash anything anywhere. Gotta check Bigtoe's mod to see how he did it.
