Many times. It always worked if the chip was in a socket. I have not tried desoldering a chip in a running machine. Modern Intel systems may cause problems if the Management Engine tries to access the flash chip while it is removed, but IO'm not an expert on that. > Or maybe Coreboot should be programmed to switch electrically off the chip > before tear out it from its case ? You can't switch off the power for the flash chip because there is no switch in the hardware. > I pose this question because, if really the Bios chip is only necessary for > the boot process of a machine, has not sense that it is on board during the > usual activity of the O.S. > > So, is it possible tear out it from its case after the boot process, when the > pc is working and the O.S. has taken into account the whole control of the pc > ? I had some older PCs work fine without a flash chip for more than 4 weeks. Obviously, they needed the flash chip for booting, but after that I had removed it. For modern systems, it depends on various components and where their firmware and/or configuration data is stored. A generic answer is not really possible anymore. > Tips are welcome.
