1. cd uboot-2015.01/ 2. CROSS_COMPILE=/path_to_my_i386_toolchain/i386-linux-uclibc- make ARCH=x86 coreboot-x86_defconfig u-boot-dtb.bin Virtualbox setup: 1. I've created a VID disk with size 64 MB with virtualbox 2. I've created a unique FAT16 primary partition and automatically the 512 MBR bytes content with PartitionGuru application, and I've loaded u-boot-dtb.bin within its content 3. I've created a VM machine (type: Other, version: Other/Unknown) and I've registered the VID disk as its storage disk managed by the SCSI controller I'm confident that MBR data has been created coherently with virtual disk geometry because earlier I have formatted the FAT16 partition and I've installed a test tool; after this MBR loads it without any error, this proofs that the partitions table has been filled correctly. > > 2015-04-28 10:25 GMT+02:00 Bin Meng <bmeng...@gmail.com>: > >> > >> Hi Francesco, > >> > >> On Tue, Apr 28, 2015 at 4:23 PM, Francesco Lucconi <lucc...@gmail.com> > >> wrote: > >> > Yes, I've readed the README.x86 document provided from uboot, I've > >> > created > >> > my u-boot-dtb.bin following the rules of coreboot-x86 recipe. > >> > I suppose I have to apply several tunings since I'm working with a PC > >> > with > >> > i7-2600 Intel Core CPU, right? > >> > Here you have the screenshots of some starting phases on virtualbox > >> > platform > >> > (I've attached the files even if I think they don't give many > >> > information). > >> > > >> > >> Looks like the 'error' message is printed by the MBR loader codes.
