Brown spot is certainly an indication of a dead 74F623. My own VX40
would manage to boot to SRM, load the kernel, and slowly die
because of correctable ECC memory errors (I assume the 74F623 is
connected to the memory subsystem). Never finnished booting.

Carefully removing and replacing the little bugger should bring the
Multia back to life, provided that there is no other pending problem.

And if you don't know where you're going, any road will take you there...
