Hello, I am using an arc gpu which functionally requires adding rebar, however my system isnt the newest so I have to modify my bios to make to run. I have ran the command as specificed in the man guide for intel 8th generation chipsets, mine is h370m pro4 which runs h370 chipset as such:
Sudo flashrom -p internal:ich_spi_mode=auto -w newamazingrebar.rom -f The output I got finished with the quote in the title, the full output is this. The last section is most important. flashrom 1.4.0 on Linux 6.17.0-23-generic (x86_64) flashrom is free software, get the source code at https://flashrom.org Cannot open file stream for /dev/mtd0 No DMI table found. Found chipset "Intel H370". 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 [email protected] including a verbose (-V) log. Thank you! Enabling flash write... SPI Configuration is locked down. FREG0: Flash Descriptor region (0x00000000-0x00000fff) is read-only. FREG1: BIOS region (0x00300000-0x00ffffff) is read-write. FREG2: Management Engine region (0x00003000-0x002fffff) is read-only. FREG3: Gigabit Ethernet region (0x00001000-0x00002fff) is read-write. Not all flash regions are freely accessible by flashrom. This is most likely due to an active ME. Please see https://flashrom.org/ME for details. At least some flash regions are write protected. For write operations, you should use a flash layout and include only writable regions. See manpage for more details. Enabling hardware sequencing because some important opcode is locked. OK. Found Winbond flash chip "W25Q128.V" (16384 kB, Programmer-specific) on internal. Reading old flash chip contents... done. check_for_unwritable_regions: cannot write/erase inside Flash Descriptor region (00000000..0x000fff). Write Failed!Uh oh. Erase/write failed. Checking if anything has changed. Reading current flash chip contents... done. Good, writing to the flash chip apparently didn't do anything. This means we have to add special support for your board, programmer or flash chip. Please report this to the mailing list at [email protected] or on IRC (see https://www.flashrom.org/Contact for details), thanks! ------------------------------------------------------------------------------- You may now reboot or simply leave the machine running.
