Re:Re: Grub2 can not detect usb disk

[崔磊]

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.

BRs,
Rock.

I think the "skip=2146422784" is too big.

  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!” : (

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.
