很多网友对BIOS芯片参数不清楚，导致在需要更换主板BIOS芯片时，找不到原型号非常苦恼，实际上许多BIOS芯片，都是可以相互换用的，只要我们了解BIOS芯片电压，类型，封装相同我们就能容易找到替用BIOS芯片。同时BIOS之家，为没有编程器的网友，免费为大家代写BIOS芯片。 芯片代换原则：相同容量的芯片，不论厂家、具体型号，从原则上来讲，是可以代换的！所以，没有必要非要找与原主板型号相同的芯片，只要是同系列（如都是FLASH ROM）、同容量、同封装，都可以相互代换。但目前市场上出现3.3V低电压HUB芯片，其大多为PLCC32封装，但由于工作电压和脚定义与5V工作电压不同，因此二者之间是不可以互换的，请网友一定注意。
