The below is the result written by my hand but expect the value is correct. ata1: <Intrepid Kauai ATA Controller> mem ~~~~~~~ irq 39 at device 13.0 on pci2 ata1: Firmware configured PIO register: 0x6149246 ata1: Firmware configured UDMA register: 0x2921 However I've encountered a another issue, kernel hang that my ad0's transfer mode is UDMA100 according to the result of atacontrol(8) $ atacontrol mode ad0 current mode = UDMA100 During compiling the kernel there was a kernel hang, no any panic messages available. It was just hang. After setting hw.ata.ata_dma=0 I could compile the kernel. regards, Weongyo Jeonghome | help
