Re: [coreboot] Fujitsu Lifebook P1610 - morely possible candidate

You mean this warning? ======================================================================== WARNING! You seem to be running flashrom on an unsupported laptop. Laptops, notebooks and netbooks are difficult to support and we recommend to use the vendor flashing utility. The embedded controller (EC) in these machines often interacts badly with flashing. See the manpage and http://www.flashrom.org/Laptops for details. If flash is shared with the EC, erase is guaranteed to brick your laptop and write may brick your laptop. Read and probe may irritate your EC and cause fan failure, backlight failure and sudden poweroff. You have been warned. ======================================================================== Use `flashrom -p internal:laptop=force_I_want_a_brick` (also see the manpage) to circumvent it, on my thinkpad x220 that just works, but as the warning says, if the flash is shared with the EC, weird things can and will happen, so i'd try an external programmer, stock BIOS is most likely write-locked anyway. Make a good backup of the stock bios and keep it safe!

Fujitsu Lifebook P1610 - morely possible candidate
by thejapanscout . 28 May '16

28 May '16

I think I may have found a likely coreboot candidate-- with hardware far more supported than the hardware on the laptop from 2005 that I posted earlier. Currently, Coreboot has no Fujitsu mobos. But the specs of this Lifebook P1610 are close to a Thinkpad X60, except for the NIC, CPU, and astonishingly the mPCIe cards. Most models of the P1610 shipped with an Ath5k Wi-Fi mPCIe card, which has free software drivers, along with the rest of the non-ME hardware, including the fingerprint reader, making it essentially free-software compatible on the software side. It also has a touch-screen, making it nifty for artists and workers that want a tablet. Before you ask, GOOD NEWS! Most of the hardware, as seen in my lspci -tvnn output, has completely added support in coreboot. It also runs off a GM45-based chipset, which can have it's ME deblobbed, making it viable for GNU libreboot. -[0000:00]-+-00.0 Intel Corporation Mobile 945GM/PM/GMS, 943/940GML and 945GT Express Memory Controller Hub [8086:27a0] +-02.0 Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller [8086:27a2] +-02.1 Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller [8086:27a6] +-1b.0 Intel Corporation NM10/ICH7 Family High Definition Audio Controller [8086:27d8] +-1c.0-[02]----00.0 Marvell Technology Group Ltd. 88E8055 PCI-E Gigabit Ethernet Controller [11ab:4363] +-1c.2-[05]----00.0 Qualcomm Atheros AR242x / AR542x Wireless Network Adapter (PCI-Express) [168c:001c] +-1d.0 Intel Corporation NM10/ICH7 Family USB UHCI Controller #1 [8086:27c8] +-1d.1 Intel Corporation NM10/ICH7 Family USB UHCI Controller #2 [8086:27c9] +-1d.2 Intel Corporation NM10/ICH7 Family USB UHCI Controller #3 [8086:27ca] +-1d.3 Intel Corporation NM10/ICH7 Family USB UHCI Controller #4 [8086:27cb] +-1d.7 Intel Corporation NM10/ICH7 Family USB2 EHCI Controller [8086:27cc] +-1e.0-[08-0c]--+-03.0 Ricoh Co Ltd RL5c476 II [1180:0476] | \-03.1 Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter [1180:0822] +-1f.0 Intel Corporation 82801GBM (ICH7-M) LPC Interface Bridge [8086:27b9] +-1f.1 Intel Corporation 82801G (ICH7 Family) IDE Controller [8086:27df] \-1f.3 Intel Corporation NM10/ICH7 Family SMBus Controller [8086:27da] SN and UUID: R7108162 13F0737D-AD13-11DB-8B14-001742268EEB Baseboard SN: FJNB1C5 superiotool -dV log: Probing for SMSC Super I/O (idregs=0x0d/0x0e) at 0x2e...

Guidance for adding SuperIO support
by Andrew Barnes 26 May '16

26 May '16

Hi, I'm new to coreboot. I would like to have it working on the following hardware: * Fujitsu D3231 (Q87) * Intel DQ87PG (Q87) * Intel DQ67OW (Q67) * Intel DQ45CB (Q45) Focusing on the first 3, which are all core-i systems, sandybridge and haswell. I *believe* that coreboot would already support the CPU and Chipsets. (If that is correct?) However, the SuperIO I know is not supported. They are respectively: * SMSC SCH5636, devid '0xc7', kdriver 'sch5636' * NCT6683D-T, devid '0xc730', kdriver 'nct6683' * W83677HG-I, devid '0xb470', kdriver 'w83627ehf' * WPCD377I, devid '0xf1', kdriver 'not-a-sensor'? I know that these chips are supported in the kernel/lm_sensors. So perhaps all the info I need to add the support into coreboot is already available? However, I'm not entirely sure how best to go about this. I don't really understand what needs to be achieved or how. I need some guidance to figure this out, is there an good example I could follow where by a driver from kernel/lm_sensors has been ported into coreboot? If I port the superIO chip successfully, is the next stage to simply create a board which combines the 3 components CPU,Chipset and SIO? or am I underestimating this? Could anyone possibly comment on how much work this will be? The SuperIO support files don't look that indepth, however if that were true, and if all the info required is already in the kernel - I wonder why coreboot doesn't already implement the same list in the kernel.

Re: [coreboot] Query regarding coreboot for new intel customized board

That looks a lot like the Valley Island design. I was able to get serial output by overwriting coreboot (last 2MB of the 8MB bios chip) on the bios that comes with it. However as you will see in the history of emails still get stuck during the boot process. Hope the above helps you get further.

The MRC cache is preserved in flash so you need to be able to write it. For the others the numbers etc you mention are informational for the OS. They are not strictly required but the OS builds a registry of the items it retrieves from the SMBIOS. If you don't require this you could also disable the functionality.
