Ok. I think the Tyan S2881 looks like the most similar candidate for the
Dl145G1 / A2210 motherboard, so I'm using that as template.

Ant I'm able to read the existing BIOS from the 512k Flash ROM
"SST49LF040" to a file using "flashrom -r" so now I have a backup. And
I'm able to compile a new image from the S2881 template in coreboot. But
do I dare to write the new image using flashrom? What happens if I can't
boot? Do I have to buy some hardware flash programming dongle?

I can see a 2x10-pin connector on the motherboard marked "LPC". Is that
where the flash programmer should be connected?

Or is it possible to program the flash even without a working BIOS
through the superio chip using the RS232 port somehow? Is that what the
"-p serprog" option in flashrom is for?

Sorry for all the questions ...
