#| Set the value of RELOCADDR to the address where you want your image to
|
|
#| load. If you'll be using GRUB to load the images it will have to be >=
|
|
#| 0x100000 (1024K). If you are using NetBoot to load the images it can be
|
|
#| >= 0x10000 (64K) AND <= 0x97C00 (607K) OR >= 0x100000 (1024K). The memory
|
|
#| top is of course another limit. Make sure there is enough space before the
|
|
#| upper memory limits for the image and the memory allocated by it to fit.
|
|
#| Make sure the value you choose is aligned to 4 bytes.
