Precision 490: CPU SUPPORT REQUEST

[Stonent]

No way.

I thought I might toss it out there that the Precision 490 and PowerEdge SC1430 have the same base motherboard.
The SC1430 has an empty spot populated for a video chip and the 16x slot is removed as well as removing half the memory slots.
(I had a Dell rep once imply that internally the "SC" designation stood for sh!tty configuration)

Both the SC1430 and 490 have the same CPU support however, since they are basically the same board.

The Precision T5400 has a 95% identical looking board to the 490 but supports 5400 series Xeons.

They bumped up the revision of the 5000 series chipset and swapped the PS/2 and Audio ports so it doesn't match the 490 backplate.
They also changed the front I/O panel connector so that it doesn't fit.  Anyone who by chance wants to do a 490 to t5400 board swap, the RAM will move right over.  You will need to get a new IO panel board and deal with the back ports not matching up perfectly.

I'm just adding this for future reference in case someone has some kind of "ah-hah!" moment or they decide to migrate to a T5400 board to get the E54xx/X54xx CPU support.
