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.

I received you reply this monday, then my office PC had a problem ,can not power on, so I write you late. I have tried to run "dd", but got "Reading a error address".

I would also need another memory location for full diagnostics: sudo dd if=/dev/mem of=tables bs=1 count=65536 skip=2146422784 Looking at the code, the only way it can hang AFAICT should be fixed by attached patch (mostly guessing) 1. 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.orghttps://lists.gnu.org/mailman/listinfo/grub-devel _______________________________________________ Grub-devel mailing list Grub-devel@gnu.orghttps://lists.gnu.org/mailman/listinfo/grub-devel _______________________________________________ Grub-devel mailing list Grub-devel@gnu.orghttps://lists.gnu.org/mailman/listinfo/grub-devel _______________________________________________ Grub-devel mailing list Grub-devel@gnu.orghttps://lists.gnu.org/mailman/listinfo/grub-devel
