table_item = (grub_linuxbios_table_item_t) ((long) table_header +
(long) table_header->size);
the (long)table_header->size, I think it is not same with coreboot.
Now I can build a payload with
"--with-platform=multiboot" that can boot my machine, not the
"--with-platform=coreboot".I have read the source code about the mmap of grub and of corebootV4, I found that the size of their table header struct are not same, and I think ,in the file "mmap.c" of grub2,on the 53rd line, the offset of the first table item may be error.In my copy 53rd line is completely empty. Could you detail the error?BRs, Rock.

I have tried the "--with-platform=multiboot" option, but when booting it show me: /*********************/ Welcome to GRUB! out of memory Aborted. /*********************/ 2. The /dev/mem you need , how can I get it? I want it should be from the "/" , then I must enter the ubuntu. So I use the grub1.98 as coreboot payload and boot my ubuntu11.04. But when I copy the /dev/mem to a log file with "sudo", I was told “You can not do it!” : (On 30.06.2011 04:38, Cui Lei wrote:I have found the the last version which can boot my machine, it is the r2348. The r2349 can not boot it. So I checked out the changelog from 2348 to 2349 :Ironically I did it because i386-coreboot didn't work in my tests. Could you send me the first 128K of /dev/mem ? Meanwhile you can try i386-multiboot port. _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel_______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel_______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel_______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel_______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
