Or try another non-modified CPU to eliminate any issues with that. I have a Socket 7 system that only supports up to UDMA-33 and in combination with a HDD that is UDMA-100 capable it always crashed at Windows 98 installation. The reason was the board expected the HDD to run at UDMA-33 while the HDD …

Thank you all for your hints. Since I don't have my test bed assembled at the moment I went ahead with the suggested measurements and voilà, we have a likely culprit. Traces separately were OK for R, G, B; resistors were OK according to their nominal values, ferrite beads were OK for G, B, but NOK …
