That is why I need a proper Intel chip. But I only see them from China. I do not want to waste my time again.

Do not know if it is related or not but here another one with problems properly flashing (hot flashing) a Intel firmware: https://www.wimsbios.com/forum/motherboard-dead-f30/49lf004a-boot-block-problem-for-experts-t9577.html It seems like there is sone fail safe process that prevents correct …

I see. Let's assume that those chinese intel EEPROMs are (most likely) relabeled non-intel chips, so you don't have another compatible EEPROM chip except this PMC PM49FL004T and the mobo is kinda alive while using it. Then if there is no some compatibility conflict with your AGP videocard (as PC …

Let’s say that all three are false. How can they pass the Xgecu ID and pin check? I do have a Xgecu T48 programmer and I also have a list of programmer's supported chips in which some of the (E)EPROMs from a different brands/makes use one and the same chip ID. I also know that some Xgecu users …

I do not think so. The chips seems original, it is not easy to replace the writings on it. Plus, the programmer would spot differences or errors. It is not a basic ch341a thing. If these used intel EEPROMs from China are genuine and exactly the same model as the original chip, then there should be …

This thing is making me mad. Tried Uniflash, hotflashing. I know it is a nonsense since I have the programmer but since the situation is so strange, I try strange things. Uniflash is not able to recognise the chip, all three of them. This could an evidence that they are false. But I read on the net …

Weird things often happen when someone's using Ali Baba's cave :) You order exact chip model, but you get some sanded and relabeled "compatible" chip. Did you tried kmeaw 's modified BIOS for the Atmel AT49LH004 chip? I do not think so. The chips seems original, it is not easy to replace the …

When you order something and get it "different"... Could it be possible that some lines of code are written elsewhere and not being part of the BIOS? Like some confirmation code in order to avoid tinkering. There is exactly the same bios file of the PM49FL004T, loaded with the same Xgecu programmer …

Ok now it gets weird…. Three chips arrived from China. All 3 seems to be ok, I read them correctly with my Xgecu programmer. So I loaded on all 3 the PIIIDME bios. Guess what? None of them works, or better, the board does not post at all with them. Post card does not show anything ( - -). It does …

Tried the amiflash utility. It says bios is write protected. I am running out of options, maybe I have to give up and wait forever for an Intel chip to reach me from China….

Check the board for a jumper. as I recall Supermicro still used a jumper to lock the bios and thus prevent anything from flashing a chip. It might also be in the bios settings, oddly enough. SM made good documentation, the manual should have detailed step-by-step instructions. "Universal AGP" is …

The Reset LED is on ? D3 is "start memory sizing" and 14 is "timer test" from the 1995-97 AMI code pdf. Maybe something wrong with the AGP slot. How much ram is installed and what AGP card ? Maybe a memory or resource conflict... There is no reset led on. The system boots fine with a pci card. I …
