Many people can't distinguish between BIOS and CMOS.

Only when using a BIOS flash logo tool can the logo be rewritten. After removing the battery, the BIOS settings will be restored... I used to have the full-screen brand machine logo you mentioned. After discharging, the boot screen shows three red triangles stacked on the left, a blue Earth on the right, and a pentagram like the Award BIOS on it. Below are English subtitles. I want to ask if this is the boot screen of AMI?

Yes. The three stacked red triangles on the left are the logo of AMI. The Earth - shaped logo on the right is an energy - related logo that most motherboards have. This logo also appears elsewhere, such as on monitors, and the power options in the "Screen Saver" tab of the Windows Display Properties.

If that's the case, then I hear a "beep" every time I start up. Does that mean there's a fault with the AMI BIOS?

Hey, I don't know why my brother would think that way. Discharging just means taking the battery out and resetting the CMOS once again. I've never heard of anyone damaging the BIOS by discharging; besides, generally, motherboards have jumpers to clear CMOS settings, and you just need to short the jumper cap for 5 seconds. The method of you pulling and inserting the BIOS chip is not only cumbersome to operate, but also some are actually soldered on the board, and what's more, the possibility of damaging the BIOS chip increases greatly.

Use the jumper next to the CMOS. Just short it by connecting pins 2 and 3. But you need to do it without shutting down the computer. I tried removing the battery, but generally it doesn't work!

There are too many methods to clear the CMOS. Hot plugging is too dangerous.
