...and we're back.
After a lot of faffing about, involving a desoldering of the bios chip, and ruining one of the legs and lifting up the PCB pads with the soldering iron in the process I've thrown in the towel, reordered a replacement mobo and put everything back in place; mods, pimped ME firmware and all. Even though the heart-surgery was not a success a lot of interesting things have been learnt/raised in the process, for instance:
1) Is it possible to actually replace the lifted PCB pads back under the BIOS chip?
2) The L511z solders the CPU to the board, so it's not that easy to remove/replace the CPU, which is a shame as I have my eyes on a nice faster quad proc running at the same wattage. Has anyone ever managed to desolder the CPU?
3) There are some (very) subtle differences between the L511z variants. It isn't even possible to flash the EEPROM dump from the L511z with motherboard revisions E0 and E1, even with the same CPU.
4) This one is quite an eye-opener. On dual-boot systems, you can set the FSB to 105MHz, and reboot into OSX with the FSB settings persist. *However* this can only be done in UEFI mode on OSX - Chameleon freezes at boot. Which raises an interesting question; has anyone fully experimented with modifying FSB settings in Windows UEFI mode?
Any updates on the 5MB firmware hacking?
