Hello vogons,

recently i found a couple of Intel Xeon 1000/256/133 Cascades core 5/12V

The attachment xeon01.jpg is no longer available

i did the swap of core from Xeon board to Coppermine interposer. it should work but it did not.
cpu is heating pretty well, reacting to fsb freq. but zero activity on flash and no post codes ( -- -- ).

The attachment xeon02.jpg is no longer available

anyone is aware of any difference between coppermine and cascades ? what did i miss there

Wow, honestly, I had no idea that this was a thing that people did.

I will be watching this thread though. I hope you get it working!

What makes you think they share common pinouts?
Let's see the ballout sheets you compared

there is no ballout sheets for Cascades
all you can find is pdf for Intel Mobile Pentium III cpu

See Table 42. Signal Listing in Order by Pin Number

You should also specify which motherboard you have and the BIOS version, ideally include a link to it.

I suppose it's possibly just a microcode issue and not hardware.

Probably best to compare the microcode of the current bios with a bios from a board which definitely supports it.

this is slot 2 pinout, not a ballout of the chip itself

ballout looks like this (mobile pentium III)
