If it didn't killed you're notebook the awnser would be yes. The only thing i could do is shift the slic around with so it seems a great risc to brick it again.
No, it must be visible in the SLIC table. If there is no SLIC table i can try someting but there is a great risc to brick you're mobo.
What is it exactly what you are going to try -different from what you've already done- ? just so I might learn something from your words. It's a rather old mobo so I can just buy a cheap new one if it gets bricked so that's not a huge problem...unless you think the brick chance is really that high, then it's not worth trying.
