Does not affect file loss.
The BIOS function is to check the hardware configuration when the computer starts up, and then boot the hard disk boot area, load the operating system boot file to start the operating system. Therefore, removing the BIOS chip will only cause the computer to fail to start normally, and damage the files inside the disk. The only impact is that the files inside the hard disk cannot be read because they cannot be started. When the BIOS chip is used normally, these files can be used normally.
