No. M72e uses two BIOS chips with 2 MB & 4 MB sizes. So full dump has 6 MB size.
I've converted it to 8 MB dump. But it didn't help.
I guess there is no way to add support for Ivy Brighe in ThinkCentre Edge 71 because it has only 4MB bios chip.
Lenovo says ThinkCentre Edge 71 supports only CPUs up to 65W TDP and only T series as i5-2xxxT.
But I can confirm that ThinkCentre Edge 71 (Type 1578) (bios 9QKT39A) works fine with i5-2400 (95W TDP).
