[coreboot] Tianocore boot fails, [GSoc] CBFS support in tiano - discussion (C Ganesh Sundar)
Hi! I tried booting ELILO (disk.img - in gpt), ubuntu windows 8(iso) on QEMU but wasn't successful. I am able to boot into serial uefi shell only(a blank fully black screen). I tried std vga ROM in QEMU too but no result. Any comments/help would be grateful. Below is the serial output: Booting EFI DVD/CDROM BlockSize : 2048 LastBlock : 1E9AF3 BlockSize : 2048 LastBlock : 7 BlockSize : 2048 LastBlock : 1E9539 PlatformBdsBootFail Boot Failed.

Since the ROM's address will be known, raw access of memory corresponding to the ROM could be done and parsing functions provided. For CBFS located elsewhere a base address could be provided as an argument. Existing cbfstool's code could be used. I would like to know if this is a correct approach. Thanking You!

[coreboot] [Gsoc 15] Interested in participating - Idea Discussion (Ganesh Sundar)
Hi! I would like to contribute to coreboot. I have configured the development environment for coreboot, tianocore and am able to build properly. I am a newbie and have been going through the code, its docs, the hardware datasheets recently. On IRC, kmalkki suggested me to start on providing header/footer encapsulation for hexdumps of memory (for lspci -F and iasl disassembly). I tried something in [2], but am very unsure if that is what he meant. patricg told some ideas related to tianocore and I am interested in working on CBFS driver for tiano. I still need more time to understand the code (particularly CBFS, libpayload and tiano), and during the period I would like to work on documentation in [1] or any other easy tasks. Kindly guide me.
