SeaBIOS was loading correctly until you changed the GBB flags, right? And CTRL+L is just not being detected any longer? Can you change the GBB flags back and determine if the legacy booting still works? > > > I have read online it may be caused by the wipe of SeaBIOS part in the > ROM. It's possible. Since you are in dev mode, could you run the following? ' iotools mmio_dump 0xffc00000 0x200000 -b | hexdump -C' It will dump the contents of legacy portion of the flash. We'd know for certain if the area is wiped. > > I need : > - - reinstall SeaBIOS, I have found this > http://permalink.gmane.org/gmane.comp.bios.coreboot.seabios/7572 but I > don't understand what "For those interested in reproducing, it will > require the very latest > seabios from the git repo." stands for .. > > - - Or maybe I can write ALL the bios file, but I need someone intact > one ...

I think we should determine if the rom area is wiped or not first. > > Thanks for reading, and I hope it's ok to ask this question here. > > Carmelo > > -----BEGIN PGP SIGNATURE----- > Version: GnuPG/MacGPG2 v2.0.20 (Darwin) > Comment: GPGTools - https://gpgtools.org > Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ > > iQIcBAEBCgAGBQJS8KUuAAoJELZV+OMrLOztPA0P/j5Lfy7uECnog4HMslLbVutM > LGX3hUuoavRRQ3+WIzC3d9H+A22zGSDp8013WjSLsezw9VVnwom0nezdqNqk6wod > 8N1rlnYc/MBRnNM3sBFzXZ6xurlGn9Ox0b4cvZn0YQxrCcwA51t5Sxv5BmGxoKTO > iysxHJFJUjv/Bx8TDgmBC3vpmIyznbGCpX0RJYhXAzjTSclVbAHRlFF1oWDlgvfe > +ODnPX9RpbVsUj2J5dBIO/HBdj1wVjk76l7rixXUDZldJUEEfT+NqyT6afYQxkjX > jOYlRV7jbK35hLfoZESgb4qoLqSfYsHO382TjdA29KshfPtulFzzipuCE7B8+wf7 > +D/uSL6qPg0fWMytF0mw57Q6KAIsv2L8pLJhHQzLRc72B+Iwa2EwJR4xe23wrtU9 > IhbHZASR5MYJJnNgsKGuYxZl2cgC19knySMw8qrP+WJHbW6JMaIAtmHpJ7/KCGl2 > bfvI2mClCWnKtQr1IgnrJ/I7O4KeAULcNWncwmuIdcaW4/41FXT57YOngc4kFGzO > JhVnnxJJ5hft7ayFvSyFIUNMRRlrjQ8IAzRqKX/JdjecmnAVCuxSUqnqtxMJkDhG > 1ydT9nEjtT0WKxkoLyUdyC7Fp7ZIGR1OpFZIpvuUWyps+L0Wjie2RWXhhEaSYk48 > da9vbaJDDf550Bu9xJFe > =jc6k > -----END PGP SIGNATURE----- > > -- > coreboot mailing list: [email protected] > http://www.coreboot.org/mailman/listinfo/coreboot -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
