Hello again, this is the utility that creates irq_tables.c dumping the current table in memory (created by the original BIOS) into a C file formatting it the way it could be used with linuxbios without modifications. When I made it, I expected that it would be equal to the BIOS original irq settings, but it is not exactly the same... well, I have to get more into this stuff to understand better irq management. Let me know what you think. Nikolai
