Hi
I would like to use your tool to mod my bios.
First step would be to create a backup of my BIOS: # dmidecode 2.12 SMBIOS 2.7 present. 66 structures occupying 2563 bytes. Table at 0x000EB4C0.
Handle 0x0000, DMI type 0, 24 bytes BIOS Information Vendor: American Megatrends Inc. Version: 4.6.5 Release Date: 10/11/2013 Address: 0xF0000 Runtime Size: 64 kB ROM Size: 3072 kB
When I read that correctly the ROM Size is 3072 kB
# flashrom -r RDD516-NT.rom --programmer internal flashrom v0.9.7-r1782 on Linux 4.4.184.x86_64.1 (x86_64) flashrom is free software, get the source code at http://www.flashrom.org
Calibrating delay loop... OK. Found chipset "Intel C206". This chipset is marked as untested. If you are using an up-to-date version of flashrom *and* were (not) able to successfully update your firmware with it, then please email a report to flashrom@flashrom.org including a verbose (-V) log. Thank you! Enabling flash write... Warning: SPI Configuration Lockdown activated. OK. Found Macronix flash chip "MX25L6405(D)" (8192 kB, SPI) at physical address 0xff800000. Found Macronix flash chip "MX25L6406E/MX25L6436E" (8192 kB, SPI) at physical address 0xff800000. Found Macronix flash chip "MX25L6445E" (8192 kB, SPI) at physical address 0xff800000. Multiple flash chip definitions match the detected chip(s): "MX25L6405(D)", "MX25L6406E/MX25L6436E", "MX25L6445E" Please specify which chip definition to use with the -c <chipname> option.
Which chip should I select? When I select one chipset a 8MB file is created. Shouldn’t a ROM back be only 3072 kB?
Any help is appreciated.
Best Regards Jochen
