Hi!
I've been reading the list for a while and learning how things work around here.
The choice of trying LinuxBIOS is mainly related to a board i've bought, that has lots of PCI devices and where the factory BIOS simply doesn't have any type of PCI sharing working properly.
There is no ACPI support.
From what I've read, making ACPI tables is not easy...
The board is industrial grade, and it can be found here: http://www.icpamerica.com/products/single_board_computers/5_25_NOVA/NOVA-489...
The version I have has the realtek ethernet chips.
Now, for my questions:
1) if I don't specify a device in config.lb, Linux will still be able to recognize it 2) about IRQ sharing, what is the best solution 3) is it possible to enable ACPI without having the tables from the factory bios
Below you'll find an 'lspci -vvv' that I managed to produce
Thanks for all the input you may provide.
