Re: [Trisquel-users] Coreboot to boot USB
Installing libftdi1 was enough to run flashrom. I don't recall removing it, but I did remove quite a few packages.
Re: [Trisquel-users] Coreboot to boot USB
Parse options tested with Trisquel 6 (gnome3) iso, Parabola iso.
Re: [Trisquel-users] Coreboot to boot USB
See my reply below regarding the updated coreboot image (plus source code).
Re: [Trisquel-users] Coreboot to boot USB
I've tested this on a drive that had the USB Mass Storage request failed bug. Now it works perfectly. I've also tested Trisquel Mini ISO. The parse options also boot that (directly from GRUB, without seabios), without having to type any commands. When selecting Parse it switches to a new GRUB menu with all the isolinux.cfg entries converted to GRUB entries. Next I'll test this on a USB DVD drive.
Re: [Trisquel-users] Coreboot to boot USB
It will remain unchanged but now you can easily change the default grub.cfg using cbfstool (the config is in CBFS now). I will write a tutorial about this at some point. cbfstool is included in coreboot source code, until ./util I have another update planned: Next update planned: - enumerate list of all ISO's on the root of a flash drive, generate menu entries for loopback mounting and booting those directly. - automatically use scan and boot the 1st menu by default* *an error appears, because the wrong prefix is set. (there are modules that most distro grub configs try to load, which aren't included in the grub payload) (the idea is to test it by setting the prefix in GRUB to use the modules provided by the distro) I think you can fix this by setting the right prefix to use the grub modules on the HDD instead of in the boot flash. I'll be testing this.
Re: [Trisquel-users] Coreboot to boot USB
The instructions are in FLASH_INSTRUCTION (file): WARNING! Updating your firmware has a risk of bricking the machine. You have been warned, and do so at your own risk. also see: README --- this assumes that you already have coreboot running and are updating it. put coreboot.rom in the flashrom directory (coreboot.rom is in ./coreboot/build) a flashrom executable is already compiled for convenience. so if you don't want to compile, just make sure it has execute permission: chmod +x ./flashrom or if you want to compile it again: make clean make --- with coreboot.rom in the flashrom directory, do this: sudo ./flashrom -p internal -w coreboot.rom -- or this command, if 3 flash chips are detected (in the case of X60's with the macronix flashchip): sudo ./flashrom -p internal -w coreboot.rom -c MX25L1605D/MX25L1608D shut down your machine after it says VERIFIED. Note: you can also use the flashrom version provided by your distro. Note: look in README for flashrom dependencies.
Re: [Trisquel-users] Coreboot to boot USB
Tested gdnewhat. Doesn't work but you can now use cat. So you can use, eg: cat (usb0)/isolinux/isolinux.cfg It might link to another .cfg file. So cat that instead. Then get the options, and adapt them. For example, I found the menu entry in there with those options on the APPEND line. Then I found where those vmlinuz and initrd Then you do (with those options): linux (usb0)/isolinux/vmlinuz0 root=live:CDLABEL=hatrack20 rootfstype=auto ro rd.live.image quiet rhgb rd.luks=0 rd.md=0 rd.dm=0 initrd (usb0)/isolinux/initrd0.img boot You can boot any distro, but not all of them work properly with the parser so in those cases you still hvae to do it manually. That is how I manually booted the ISO. This is necessary in those cases where the parse options don't work properly. (for example, it couldn't boot gdnewhat or gnewsense - but it worked with Trisquel Mini, Trisuel and Parabola) (usb0) means I'm assuming you used dd on the flash drive directly, and not on a partition.
Re: [Trisquel-users] Coreboot to boot USB
For those who are reading this, this assumes you already have coreboot. This won't work if you have Lenovo BIOS (there are some extra steps involved). -- wget http://gluglug.org.uk/X60/release/3/X60_source.tar.gz Here is what I did: tar -xf X60_source.tar.gz cd X60_source/flashrom or cd X60_binary/flashrom Note: I already have flashrom dependencies installed. Get the list in README. make clean make cp ../coreboot/build/coreboot.rom . Note: if you downloaded X60_binary.tar.gz, do this instead: cp ../coreboot.rom . sudo ./flashrom -p internal -w coreboot.rom If it shows *VERIFIED* written at the end, then it worked. At this point, shut down the machine (shut it down fully! Do not sleep/reboot). --- If you didn't see that output above, you will have seen this instead: $ sudo ./flashrom -p internal -w coreboot.rom [sudo] password for user: flashrom v0.9.7-r on Linux 3.12.4-gnu (i686) flashrom is free software, get the source code at http://www.flashrom.org Calibrating delay loop...

So I do this instead (on my X60): sudo ./flashrom -p internal -w coreboot.rom -c MX25L1605D/MX25L1608D And then I see that same successful output as above: $ sudo ./flashrom -p internal -w coreboot.rom -c MX25L1605D/MX25L1608D flashrom v0.9.7-r on Linux 3.12.4-gnu (i686) flashrom is free software, get the source code at http://www.flashrom.org Calibrating delay loop...

Re: [Trisquel-users] Coreboot to boot USB
See my note below (in this thread) about gdnewhat.
Re: [Trisquel-users] Coreboot to boot USB
Adding to note: working on a new update which should solve these issues. (on the weekend of Saturday, February 15th)
Re: [Trisquel-users] Coreboot to boot USB
Most probably it is a stupid thing, but can't it chain somehow? Let the drive do the job. I have no idea how the magic of the proprietary BIOS works.
Re: [Trisquel-users] Coreboot to boot USB
I just tried the SeaBIOS with the Gluglug X60 docked. Serial means not access to a serial port, but a second computer to read the Serial output and give a particular input based on that output?
Re: [Trisquel-users] Coreboot to boot USB
Problem solved thanks to Mr. Rowe. I'll be back with more details.
Re: [Trisquel-users] Coreboot to boot USB
chainloader will not work as this requires a bios* (this is why it is necessary to boot a kernel and ramdisk directly). *the gluglug x60 uses GRUB2 payload instead of SeaBIOS.
Re: [Trisquel-users] Coreboot to boot USB
To view serial output, connect the null modem cable to the dock and connect the other end via the USB serial adapter, to your other machine. On that other machine, there are several ways to monitor serial output. The way I use is: sudo screen /dev/ttyUSB0 115200 (if you don't have GNU Screen: sudo apt-get install screen) The SeaBIOS payload is redundanty, strictly speaking. It will not be included in later updates. (instead, a SYSLINUX parser from the latest GRUB will be included, which makes booting ISO's much easier).
Re: [Trisquel-users] Coreboot to boot USB
Thank you. It beats the purpose of a Live system. But it looks workable.
Re: [Trisquel-users] Coreboot to boot USB
Example (USB): linux (usb0)/vmlinuz idle=halt initrd (usb0)/initrd.gz boot Or CD (on the dock): linux (ata0)/vmlinuz idle=halt initrd (ata0)/initrd.gz boot idle=halt turns off CPU throttling, which removes the whining noise. This is a workaround for a bug in the way coreboot handles power states. It happens when the CPU is idle (running at a lower speed).
Re: [Trisquel-users] Coreboot to boot USB
You can boot with USB. Not all drives work currently (GRUB2 USB mass storage support is incomplete). This is a common issue that will hopefully be addressed in the near future. The ones I have and recommend: Kingston DT101 G2 (8GB). There are others but this is what I have. (they work flawlessly in GRUB).
Re: [Trisquel-users] Coreboot to boot USB
You can boot USB in GRUB2 but you have to directly boot the kernel/ramdisk. Some example entries are in the menu. There is a newer version of GRUB available that can parse the SYSLINUX menu (isolinux.cfg) of most ISO's and automatically create GRUB menu entries. I plan on issuing an updated coreboot image in the near future, with this parses included and some menuentries that use it. This should make booting ISO's easier. Currently there are some pre-defined menuentries for common FSDG distros (Trisquel, Parabola, gNewSense).
Re: [Trisquel-users] Coreboot to boot USB
http://git.savannah.gnu.org/cgit/grub.git/tree/grub-core/commands/syslinuxcfg.c And an example that uses it: http://git.savannah.gnu.org/cgit/grub.git/tree/docs/osdetect.cfg
Re: [Trisquel-users] Coreboot to boot USB
Sure. One of the many options says 'Boot SeaBIOS (requires serial ouput, baud 115200) (for booting USB drives)' Only it's one of those useless options. After a dark screen it defaults to normal boot. And a strange rather faint high pitch sounds that remains until I shut the system down. Weird, because Mr. Rowe, in one of the messages prior to the purchase wrote to me that coreboot can boot USB without the need of SeaBIOS.
Re: [Trisquel-users] Coreboot to boot USB
It seems booting into USB is buggy currently. In the readme included in the sources I found this sentence: GRUB2 USB support is buggy/temporamental at the time of writing I also get the high-pitched noise when trying to boot using the SeaBios.
Re: [Trisquel-users] Coreboot to boot USB
So the only way out is plugging the docking station for those who have it and bare with the noise till they install another system. Not a nice perspective.
Re: [Trisquel-users] Coreboot to boot USB
You may want to use SeaBIOS as a payload to have support for USB devices.
