irq_routing_table can't be copied to 0xf0000

[zhu shi song]

yes, irq_tables.c is:
/* This file was generated by getpir.c, do not modify!
   (but if you do, please run checkpir on it to verify)
   Contains the IRQ Routing Table dumped directly from your memory , wich BIOS sets up
   Documentation at : http://www.microsoft.com/hwdev/busbios/PCIIRQ.HTM

Have you run getpir to get the correct pirq table?
