+ABOUT:
+
+This utility will help to create irq_table.c file, that is very hard to create manually,
+specialy when you are testing new motherboards, changing your hardware often, placing new cards, etc..
+
+
+INSTALL:
+
+edit Makefile, define the root to Linuxbios tree
+make
+
+USAGE:
+
+./getpir
+
+Will dump irq table to the file called irq_tables.c, ready to use with Linuxbios. Just move the
+file to corresponding place in the linux bios tree.
+
+
+CHECKING CUSTOM irq_tables.c:
+
+checkpir.c Will verify the irq_tables.c, currently it only checks the checksum. In case of wrong
+checksum, a good value is proposed, so you can edit irq_tables.c manualy and replace checksum.
+Run the command like this:
+
+make test
+
+Do not run ./checkpir directly because it needs to be linked to irq_table.o first.
