Nothing prepared, no. Of course you could put defaults into code for
your particular target.

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 …

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.

Using the lxbios utility. See http://lxbios.sf.net/

I'm trying to get LinuxBIOS booting on a custom board with a Socket
AM2 Athlon and an MCP55. There is no SuperIO; instead, we're using the
MCP55's internal serial UART. A couple of the MCP55's GPIO pins are
hooked up to LEDs.
I have had no luck getting either the serial port or the LEDs to work,
though. My cache_as_ram_main() sets up the serial port by:
- enabling the serial port and configuring the IO address and IRQ in
register 0x78 on PCI device 1:0
- NOT redirecting IO address 0x3f8 to …
[View More]the LPC bus in register 0xa0 on
PCI device 1:0 (as is done when the serial port is on a SuperIO)
- setting GPIO pins 11, 12, 13 and 14 to their "normal" (non-GPIO)
mode, which I hope is RX, TX, DTR and DSR
It also tries to turn on an LED on GPIO pin 1 by setting it to GPIO
output mode, drive low.
Has anyone tried tried this with an MCP55-based board? Any ideas for
other ways to communicate with the outside world when the serial port
doesn't work?

Hello everyone,
I do have a question. What is the purpose of the cmos.layout file.
Does this come from the DMI of the original bios? What other source
files use this file?
Thanks - Joe
