I rescued the P3bf mobo from recycler center. The mobo looks good condition but the ASUS ASIC chip is demaged. In the manual only says something like a hardware monitor. So no luck?

Retro rig 1: Asus CUV4X, VIA c3 800, Voodoo Banshee (Diamond fusion) and SB32 ct3670.
Retro rig 2: Intel DX2 66, SB16 Ct1740 and Cirrus Logic VLB.

salvageable, get a razor and try VERY carefully bending pins apart, they dont have to be super straight, just not shorting
even if you rip some pins by accident its not game over, you can dremel out outer plastic to get to the lead frame

Wow... somehow I never realized that's what was going on inside a plastic chip package. I do pin repairs from time to time (some not so successful), so thank you for that! 😀

Now for some blitting from the back buffer.
