hi, I'd flashed the official BIOS 1.34 from Acer and it deactivated the configuration pages. Recovered with the Esc + Fn method but UUID and Serial Number had been erased. Tried all DMI tools availble here including Compal V.3.00, Inventec, dmicfg and even dmiscope. None is able to write/save to the dmi area. Some tools show written but once rebooted, the data is gone. Any help from the experts here is appreciated. Thanks! Acer was unwilling to email or provide the dmi utility even though the problem was due to their official firmware update.
