New subject: RAMBASE and ROMBASE?

19 Nov 2003


      Hi,
    RAMBASE address is given as 0x4000. Then if it is the lowest RAM address 
used by linuxbios. Is it right? If so the memory sizing in 
freebios/src/northbridge/raminit.inc is done based on address 0. The lower 
address ic 0 or 0x4000. I have an 32 MB SDRAM anf 4MB flash memory. Then in 
hardware, the SDRAM must be mapped from 0x0000000-0x1FFFFFF and Flash memory 
from 0xFFFFFFFF-0xFFC00000. Am i right at this point? Plz give me suggestion 
on this.

Hi,
     What address does _RAMBASE and _ROMBASE represent?
_RAMBASE is the lowest address used by LinuxBIOS i guess.
_ROMBASE is the address of the flash rom.
I think the names are pretty expressive.
You find a description of all available options in
freebios2/src/config/Options.lb btw.
