1st boot, press F2, write service tag, disable Absolute, save, restart. 2nd boot press Alt+F to exit manufacturing mode.
Good luck.

Thank you so much.
BTW,would you tell me what does this WINBOND 25Q80EW do?it is a 8Mb chip.

[SMDFlea]

It is 8 Mega bits, which is 1 Mega Byte .8Mb = 1MB .That chip is for thunderbolt firmware or something else, it isn`t the bios chip.

Hello everybody.

I soldered a bios chip(XM25RH128C) to CH341A adaper and got a bin file.When I tried to patch it,patcher show an error "wa nakit-an ang intel signature".

I tired three times and all the bios files have the same MD5.

The programmer software is AsProgrammer_2.1.2.

I am sure the bios chip is soldered correctly.

Would someone can help to check where is wrong to me?

Thank you so much.

Wrong chip. Select chip with number 256.

Hello,thank you for your reply.

The 5540 motherboard has 2 chips related to bios.One is 16MB(XM25RH128C),and the other is 32MB(XM25QH256C). We only need to read,patch bin file and then re-write the 32MB chip,is that right??

Thanks.
