Hello. I don't know the laptop computer model for there is no stickers at the bottom of the notebook and it has freedos OS. It means there is no slic its bios and it has HP/Compaq CQ57 motherboard and insyde bios. The method I tried was like: 1. downloaded the sp55088.exe from HP site. 2. tested the sp55088.exe with the laptop and it worked! so the bios is right. 3. unzip sp55088.exe and it has tree fd files: 03672.fd, 03674.fd, 03676.fd. 4. downloaded the latest RW everything. I tested 1.47 & 1.5.1 but the result was same. 5. downloaded phoenix tool v.1.92. and I had SLIC and SLP already. 6. tried with phoenix tool(default: SSV2) and 03672.fd. It gives me "unable to add SLIC code" error message. 7. tried with dynamic mode in phoenix tool and it gave me no error message. so I thought it worked. 8. did the same process with 03674.fd and 03676.fd. 9 copied the three modifed fd files to unzipped folder(sp55088) and remove original files and renamed three fd files. 10. executed the insydeFlash.exe and I got message: "The BIOS image is corrupted or does not contain the correct digital signature. The system BIOS will not be updated." thanks.
