Dobrii denj/Hello Vladimir, Your advices definitely move me forward, but I was not able still to boot to grub. The good thing, I see that postcodes changed. It was hanging to 0x00F8, now it is hanging at 0x00EE! Definitely, some progress.
I changed my /etc/default/grub file to the following: GRUB_SERIAL_COMMAND="serial --unit=0 --speed=115200" GRUB_TERMINAL_INPUT="usb_keyboard" GRUB_TERMINAL_OUTPUT="serial vga_text" I use grub_2.00 from tarball I found on grub.org . I tried to adopt your lengthy command, and here is what I have got: pkgdatadir=. ./grub-mkstandalone --grub-mkimage=./grub-mkimage -O i386-coreboot -o ~/projects/payload.elf --modules='ahci ehci usbms part_msdos ext2 fat at_keyboard part_gpt' It does not recognize modules: usbserial, usbdebug and cbfs It does not recognize command: --install-modules='... It does not recognize commands: --fonts= --themes= --locales It built for me payload.elf appr. 1.7M size. Good sign. I guess, it is misconfiguration which keeps me off the guard. Do you have your command used/implemented maybe for latest grub (version 2.17??)? How I can get the latest released tarball (I see only 2.00). Can I use git clone command from your repo to clone latest grub source code snapshot? Commands from http://www.gnu.org/software/grub/grub-download.html I do not understand, and they don't work for me.

Only vga_text for output and at_keyboard/usb_keyboard for input. Most likely you don't have appropriate modules in core.img for your install (I'm not sure it adds *hci/pata modules on coreboot the way it should) > Still not able to bring it to grub> prompt...

You need to use either SeaBIOS or EFI for this. I launch seabios from GRUB. In my GRUB menu I have a choice between loading Linux or FreeBSD directly or go through SeaBIOS which allows i.a. go to windows (7 or 8 would both work this way). I have also other entries like OFW but their usefulness is limited. _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel Intel GmbH Dornacher Strasse 1 85622 Feldkirchen/Muenchen, Deutschland Sitz der Gesellschaft: Feldkirchen bei Muenchen Geschaeftsfuehrer: Christian Lamprechter, Hannes Schwaderer, Douglas Lusk Registergericht: Muenchen HRB 47456 Ust.-IdNr./VAT Registration No.: DE129385895 Citibank Frankfurt a.M.
