I am assuming that my FireMV 2250 card may be bad as it wont boot in the pciex16 slot.

Tried with a FirePro 2260 card in pciex16 slot to makes sure
my USB boot media was ok.
It boots Morphos ok in the PCIEx16 slot .

0x1002 0x95CF Advanced Micro Devices, RV620 GL [FirePro 2260]

But no luck in the dual card setting .

So card id issues for dual card configuration or X5000/40 issue with dual cards .
