Could someone help me?

My NetBSD machine(660AV) send the error off into /var/log/messages when it boots.
A part of messages as follows:

Jun  1 07:10:34  /netbsd: NetBSD 1.3.2 (GENERIC) #0: Sun May 17 00:23:35 CDT 1998

Jun  1 07:10:38  /netbsd: root file system type: ffs
Jun  1 07:10:37  savecore: /netbsd: kvm_dump_mkheader: Read: Invalid argument

This Invalid argument messages appear once more just after　"starting rpc daemons:"
I tried to type this following commands:
mv /var/db/kvm.db /var/db/kvm.db.org;
kvm_mkdb;
savecore -c
But the condition of affairs here remains unchanged.

I partitioned internal HD with Apple HD Setup v7.2 in order Root&User 320MB,
Swap 40MB,HFS 140MB and formatted only Root&User partition with MKFS_1.45.
Is it something wrong with me?

Thanks.
