Support for ASM1166
by Master 07 Feb '25

07 Feb '25

Hello everyone, I hope you're doing fine ; - ) I am in the need to be able read and write the flash, under linux, of boards containing this component : ASM166 : https://www.asmedia.com.tw/product/45aYq54sP8Qh7WH8/58dYQ8bxZ4UR9wG5 through the PCIe bus. I have read a lot of stuff, but I may not be enough knowledgeable to sort out by myself where to start from to be able to add the support of this ASM1166 through the PCIe bus by myself. If someone is willing to help, I am willing to provide back what is necessary. Thanks in advance, Have a nice day Mickaël.

Dear All, I'm new. I write in this list because I hope someone can help me. I need to read a S2430 or S24H30 EEprom from a car radio, but I'm trouble and so I ask if someone can help me. At the moment I have XGequ pro and T48 programmer but I have also a CoRight SkyPro Program suppose with EZ2019. I can buy also s new programmer, but I need to read the above chip. Someone can help me with my programmer or give me right information for a new programmer? regards Luca

Hi I have tested reading and writing bios to mainboard ASUS M2N-XE. I have attached the relative logs. This were the command I've executed: flashrom --programmer internal --output backup.log -r backup.bin flashrom --programmer internal --output write-0211.log -w 0211.ROM Cheers -- Mladen Milinkovic GPG/PGP: EF9D9B26

probing logic in command line vs libflashrom
by Anastasia Klimchuk 27 Jan '25

27 Jan '25

Hello everyone, It turns out, flashrom has two different code paths for probing from command line vs probing with libflashrom. I think the logic should be the same, so as a goal I want to understand which approach is correct and use the same in both places. Have one piece of code and call it in two places. What is the difference: Command line keeps probing until the end of flashchips array, and as a result all matches will be found (no matter how many of them are). Currently code is on these lines: https://github.com/flashrom/flashrom/blob/main/cli_classic.c#L1211 Libflashrom only does probing twice, so at most two matches will be found. Currently code is on these lines: https://github.com/flashrom/flashrom/blob/main/libflashrom.c#L250 These two paths were initially introduced like this (>14 and >7yr ago). To me, command line's approach makes sense - because why stop at two matches? What if there are three matching chip definitions, and #3 is actually what the user has? So I am interested in what people think. A context how did this come up: I started working towards giving SFDP-detection more priority and this involves updating the probing logic, and that's how I came to this. -- Anastasia.

HP Compaq 8300 Elite - NVMe BIOS Update Error
by Manuel del Rey Carral 23 Jan '25

23 Jan '25

Dear flashroom.org friends. I am the owner of a HP Compact 8300 Elite Microtower and I tryed to follow the instructions of Paul Murana below, to modify the BIOS of my PC so that it allows the Start from a NVMe SSD. https://tachytelic.net/2022/01/hp-compaq-8300-nvme/ [https://tachytelic.net/wp-content/uploads/HP-Compaq-8300-Elite-NVMe.png]<https://tachytelic.net/2022/01/hp-compaq-8300-nvme/> Install and boot from an NVMe SSD on a HP Compaq Elite 8300 SFF - Tachytelic.net<https://tachytelic.net/2022/01/hp-compaq-8300-nvme/> Hola, intento implementar esto en un HP Z230 SFF, de momento no lo he probado, solo he encontrado las guías para poder hacerlo. Os adjunto 3 enlaces sobre como instalar NVMe M.2 pcie, reprogramando la bios por software (1 y 2) o, alternativamente, mediante un simple arranque alternativo del bios (3). tachytelic.net All good, but I've got an error in the very last step: flashing the corrected bin file (nvme.bin) . The error is: Error: Unknown chip 'MT25Q128' specified. The computer remainis ok, but the corrected BIOS could not be flashed. Any ideas of what migh have gone wrong? I previosly updated the BIOS to the version K01 v03 08 and installed a jumper cap into the FDO. You can find attached the outpot of the terminal log and below the Specs of my PC. I want to take the chance to give a big thanks to Pauli for his work and sharing his knowledge, and to you for yor kind sppport. Best Regards, Manuel dRC [cid:af5e4dfd-b870-4d4d-b9e7-c1a682be500f]

Re: BIOS update fails on a Minix Z100-0db device
by Robert 07 Jan '25

Thank you Alex, this is very useful info. So if I am on 0161 now, do I have to go 0171 then 0181 then 0191? One more question: how do I back up the product key exactly? I already tried to update to 0181 with flashrom, but that failed, then reverte to 0161 with flashrom that succeeded. I hope I did not erase the product key? regards, Robert On Mon, 2025-01-06 at 11:25 +0800, Alex Lui wrote: > Dear Robert, > > Many thanks for contacting us. > > What is the currently BIOS version (project version) on NEO Z100-0dB? > When booting, press the "DEL" key repeatedly to enter the BIOS > homepage.
