hello gents, question here

I'm using the Intel D848PMB chipset and I'd like to flash the BIOS (because it seems to have gotten a bit messed up after the battery died. I changed the batt but it still doesn't detect hardware well). I've already checked to see if my chipset is supported, and it is. Ran "sudo flashrom" and got -desktop:~$ sudo flashrom flashrom v0.9.1-r946 No coreboot table found. Found chipset "Intel ICH5/ICH5R", enabling flash write... OK. This chipset supports the following protocols: Non-SPI. Calibrating delay loop... OK. Found chip "Intel 82802AB" (512 KB, FWH) at physical address 0xfff80000. === This flash part has status UNTESTED for operations: ERASE Please email a report to flashrom(a)flashrom.org if any of the above operations work correctly for you with this flash part. Please include the flashrom output with the additional -V option for all operations you tested (-V, -rV, -wV, -EV), and mention which mainboard or programmer you tested.

info test run for socket 939 board mATX MSI 6100-939
by M Capoferri 05 Nov '10

05 Nov '10

Hi, I installed flashrom last night and ran the plain command and one with -V just to see what it dumped. I'm a non-pro and was forced into learning linux after having all of my machines infected by an eeprom based rootkit four years ago. It infected eight new motherboards and a few old machines before I gave up (read went broke!) and mutilple peripherals. I was unable to connect to the net between Aug 2006 and Jan 2009. I was finally able to reconnect after getting OpenSUSE 10.3 to sucessfully install to a hard drive (coincidently, the same time the new linux module, Policykit started trials I believe). Failed after 4 weeks but was able to maintain connection using live distros. I remain infected to this day (only partial root control) as some kind of minimal kernal or control framework using busybox is still in my eeprom and hooks control of all hardware. This prevented me from reflashing my BIOS on any of the boards and believe me, i tried multiple times. I'm hoping to try and reflash this or one of my three Asus boards that are on the Coreboot approved list. I'll let you know if i succeed, if I can ever figure out what I'm doing. I'm 56, so it's a little tougher especially as I was never in IT until I started building my own machines a couple of years before the malware hit. I've attached the terminal out as both pdf and txt file (8859-1), and I guess I don't have to warn you to scan them, though i am using gmail. Cheers, Mark Capoferri Ardmore, Pennsylvania US

Asus M2N
by Miguel Angel GSM 04 Nov '10

04 Nov '10

I hope that this helps. I have one question. Is it safe for me to write the much newer version 0808 of the BIOS (that I downloaded from ASUS) with my actual settings? I ask because of the following sentence while running flashrom: "Found chipset "NVIDIA MCP61", enabling flash write... chipset PCI ID is 10de:03e0, This chipset is not really supported yet. Guesswork..."

[PATCH] Real partial writes
by Carl-Daniel Hailfinger 04 Nov '10

04 Nov '10

If you're going to review this, make sure you keep a stack of bananas (quickly mobilized carbohydrates for your brain), a bucket of ice (to prevent brain overheating) and a bottle of aspirin handy. If any code is unclear, please tell me and I'll try to add comments to improve readability. If you're going to test this, please be advised that I have not tested execution, only compilation. Testing erase (and checking with a separate readback that erase actually worked) and write (same test with separate readback) would be highly appreciated. Verbose logs are even more appreciated. This patch makes flashrom use real partial writes. If you write an image full of 0xff, flashrom will erase and detect that no write is needed. If you write an image which differs only in some parts from the current flash contents, flashrom will detect that and not touch unchanged areas.
