nata* drivers are compiled in an SMP kernel, running on Athlon64X2 with ASRock 939Dual-SATA2 . If I yank off the DVD-ROM drive from the system, it proceeds to mount root fs, then failed:
Mounting root from ufs:/dev/ad0s1h no such device 'ad'
Although this mother board has a SATA port, the IDE drives are PATA one and connected to the PATA ports. Another machine whose root fs is on a SCSI drive booted without a problem.
