Hello, I'm trying to get my Toshiba Tecra S11-113 bios modded since a couple of days now without success. The bios file itself is a .COM file of 1116kb. It's not really an executable file since the are no normal .com file headers. It should contain a 1M ROM image. I've tried quite every method to extract / decode that file without success. I've also played with the provied flash tools (chgbiosf.exe for DOS and nchgbios2.exe for WinNT) to see whether it decompresses the bios anywhere, but without success. I've also tried another way, backing up my bios with Universal Bios Backup Tool v2. It reads me a 1mb bios file. When i try to open this with Phoenix Bios editor 2.2.1.3, i get "No BCP's found". I also tried flashrom from linux to backup, i get the same 1mb file that i can't open with Phoenix Bios Editor. I can indeed read the bios with Phoenix Bios Tool v1.5. It says it's an Insyde / EFI Bios. But then, how can i flash this one back ? I googled around and found uniflash 1.40, but it does not support any recent chips so it would probably fail. Link to the bios file: http :// support.toshiba-tro.de/tedd-files2/0/bios-20100823102122.zip Please has anybody a clue ? Thanks.
Phoenix Tool 1.57 allows you to manually edit modules and then recompress the bios (It's in the advanced options menu). Open the bios with PT then it will extract, modify what you want and the program will detect the changes, recompile and flash. This should work
Thank you for your reply. But the bios file is a .com and not a .rom / .wph or .fd file so i'll not be able to recompress the dumped rom to the .com format the flash utility will like.
Not familiar with Insyde but maybe you can use PT to modify it then repackage it in a different format and flash with a different flash utility? (Make sure you have your crisis disk/recovery method ready though)
