If anyone out there is crazy enough to try this I can help them get
started.
>From what I recall, the L440GX+ has an Altera chip with an undocumented
state machine that has a line that gets ANDed with the ISA Write Enable
path to the Flash. The state machine is programmed through the power
management general purpose IO registers. I never figured out the state
machine despite many hours of watching the flash program instruction by
instruction, but I do know exactly what pins connect to what; it is a
relatively simple task to solder the AND buffer to GND (I've been lying --
this is all logic low, so it is a WE# line and an OR gate, I think).
Despite Ron's attempts to throw out the schematics, I still have a copy
downstairs that I'd gladly pass on.
However, even after doing this I couldn't get the flash device to program,
even though the signals on the oscilloscope looked right... There is a
"lock" mode on that flash device that I didn't look at too much, but I'd
venture the lock mode is on. Perhaps someone with more flash device
experience or a bit more time could figure it out.
