鵝不也早就說過 (http://forum.pcdvd.com.tw/showpost....64&postcount=24)BIOS都會有check sum,SLIC應該也是類似的,沒用適當的工具亂改一通輕則OS無法認證(反正狀況也不會更糟了:ase),重則BIOS會變成check sum error,運氣好或許還有機會靠boot block燒回來,運氣不好的話就只有送修一途了,既然愛玩搞砸時有本事自己善後就算了,沒辦法DIY的話被charge也只有摸摸鼻子認了的份,更何況人損收個NT$400應該不算過份吧:ase:ase....

這邊怪異的是

更動的是SLIC部分

引用:

Each SLIC consists of a pubkey, a marker and of the SLIC table header.
You can divide each SLIC into it:

Each pubkey starts with "00 00 00 00 9C" and is 156 bytes long (9Ch). It contains the RSA1 sting.

Each marker starts with "01 00 00 00 B6" and is of course 182 bytes long (B6h) It's named with OEM table and table ID plus "WINDOWS".

Mark them and save them as a unique file!

結果也包含到check sum?

還是說check sum其實是檢查這串位置內的字元

只要一不符合

就判定checksum error ?
