Hi All!
Please, help me to solve the problem, I fell into the hands of Nan Tan FMA7500AC, at startup it displays messages:
"CMOS system options not set"
"CMOS display type mismatch"
At the time of loading when pressing the DEL button writes a "keyboard error". Offers to press F1 to resume and when entering BIOS asks for a password "Enter ROM password". But you cannot enter any character from the keyboard, only the esc and enter buttons work. You press enter or esc three times, and that's it - a blinking face symbol pops up. Connecting an external keyboard does not correct the situation. Installed a new BIOS battery.
This situation arose after the battery was replaced, before that it was normal to enter the BIOS, but the settings were not saved.
