Hi,
I've prepared some superiotool dumps of different machines (servers, workstations). The command was run like this: superiotool -d --extra-dump
You'll find the dumps at: http://simon.trypill.org/downloads/coreboot/superio_dumps
They currently include boards from: Asus Gigabyte Intel Dell Supermicro Tyan
The name of each dump indicates the board name (for Dell, server-name)
I hope somebody finds this helpful :-)
