Hey, Debbie, stop discussing the fake quotation about BIOS.
1st Password in BIOS is entered BOTH!
2nd The password and BIOS settings are NOT stored in power-independent memory and are easily discarded by removing the battery or a special switch [CLEAR_CMOS] (who is more convenient, there is no difference).
Three The BIOS can be cleaned through various special programs.
4 is BIOS is a program. CMOS is the technology by which the chip is manufactured, essentially the chip itself, which has both an energy-independent memory in which the BIOS is recorded and an energy-dependent memory in which the settings are stored. So in a practical sense, the phrases "drop BIOS" and "clean CMOS" are absolutely equivalent.
5 is There is no need to build experts and stick to the words. Everyone understands what you are talking about without your comments.
