No, we need it under factory bios.
the one generated by vendor BIOS:
$ cd util/getpir $ make test .... Validating checksum, file: irq_tables.c that was in ./ at compile time... (no other tests are done) BAD CHECKSUM for IRQ Routing table !!!! If you want to make it valid, change the checksum to: 0x73
I will try what it suggests.
Where is this information used? By Linuxbios or Linux?
What messages would indicate that either of those has detected the table correctly or incorrectly?
