Is there a way to store cmos settings in the BIOS flash chip?
Nothing prepared, no. Of course you could put defaults into code for your particular target.
Or is there another way of resolving the issue of an unpowered cmos? (no battery)
So far the settings in CMOS have not really been critical to the boot process. At most there's the fallback vs. normal setting which indicates how the system booted the last time.
Does it matters what flash chip you use? Is linuxbios compatible with all? I'm talking about sizes at about 1Mbyte.
No, it doesn't matter. Any flash chip that works with the northbridge is fine for runtime. Note that the flashrom utility only knows how to program a limited number of chips however, so if you want to use that to flash your BIOS, check out util/flashrom/README for a list.
I'm also curious of how you apply settings during run-time. Is it all done through the serial port or via telnet or how...?
Using the lxbios utility. See http://lxbios.sf.net/
