mini pci whitelist

[lulu]

Hello,
I modified my phoenix bios on a presario r3000 to force him to accept an unauthorized mini pci wireless card...
I localized the authorized pci id and modified one instance by the id of my new wireless card.
I did a hot plug before to verify that the card works on the laptop.
then looked for the checksum byte to modify but didn't find anything.
I decided to flash anyway but the system stoped.
Hopefully I had a new chip an unsolded the old one to put a new one.
Could someone help me please to find this checksum (if there is).
Thanks
