Can Uniflash damage a BIOS chip?

Recommended by Wim's BIOS...

I don't mean just erase it but actually cause physical damage by using the wrong programming voltage or method when a different type of flash ROM is hot swapped for the original one. Does Uniflash always check the chip type, or should we always do this manually just after we insert the new chip?

UniFlash will not damage anything.
If you for example insert 512KB chip (which has address pin A18 instead of VPP) into a board that has 12V on the VPP pin, you will damage the chip and/or the board.
The voltages cannot be controlled by software - some boards have jumper to select 5V/12V voltage on the VPP pin.
