About coreboot table , where is
its location in memory ? Its size ? Its contents ? Is it
saved in buffer ?
The coreboot table typically lives at the end of physical memory in
the 4G space (e.g. in "cbmem space"). There is a
forwarder entry pointing to it, living in the lower 4k of memory
(typically at 0x500)
The coreboot table contains various information coreboot collects
about the system, such as
- memory map
- coreboot version
- cmos options
- framebuffer configuration
You can use the nvramtool utility to dump the coreboot table and
look at it.
