Chapter 5. Installation and Testing
-b < addr>
Parameter block address. This is normally the first page of the kernel image and defaults to 0x8c101000
-i < addr>
Start address of initrd image
-j < size>
Size of initrd image
-c "args"
Kernel arguments string
-m < flags>
Mount rdonly flags. If set to a non-zero value the root partition will be mounted read-only.
-f < flags>
RAM disk flags. Should normally be 0x4000
-r < device number>
Root device specification. /dev/ram is 0x0101
-l < type>
Loader type
Finally the kernel entry address can be specified as an optional argument. The default is 0x8c102000
On the HS7729PCI, Linux expects to be loaded at address 0x8c101000 with the entry point at 0x8c102000. This
is configurable in the kernel using the CONFIG_MEMORY_START option.
Memory Maps
RedBoot sets up the following memory map on the HS7729PCI board.
