I get the same error: atlas% dmesg | grep -i adv adv0: port 0x1000-0x10ff mem 0xf0000000-0xf00000ff irq 11 at device 13.0 on pci0 adv0: Warning EEPROM Checksum mismatch.

You may have better luck on the -scsi list. $.02, /Mikko -- Mikko Työläjärvi_______________________________________mikko@rsasecurity.com RSA Security To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
