I am using XUbuntu 11.10
From grub I would like to read and write a byte to a
file located in /boot/grub folder from grub. I checked all modules that
are available in folder /boot/grub/i386-pc. reading from file seems to
be possible. But, I did not find a way to write to file. Can someone in
this forums please help me ?
If it is not possible, I can create a small 1MB partition for this data, which is exactly at 8GB offset. Is it possible to read and write from this offset ?
Since grub can read from MBR, I think it could be possible to read and write from offset 8GB. Please help me.
