unexpected IO-APIC

Today (1-2-2003) I've installed linux kernel 2.4.10 and while booting, kernel shows the following message:

IO APIC #4......
.... register #00: 04000000
....... : physical APIC id: 04
.... register #01: 00178020
....... : max redirection entries: 0017

I've attached complete listing of dmesg to this mail.

The mainboard of computer is a ASUS P4T533-C with an intel pentium IV.

All seems work correctly.
