Perhaps a script in "/usr/local/etc/rc.d"... but before it is run, ad0 will be UDMA66. Wherever you put an atacontrol command, ad0 will be UDMA66 before that (outside of modifying the kernel), which might cause some trouble. A solution might be to first set all drives into PIO (by adding hw.ata.ata_dma=0 in the loader config) and `atacontrol' them in rc.d to their speeds (both to UDMA33). This may cause the boot to be somewhat slower. > Thank you! > > Marshall > > -- DoubleF Nondeterminism means never having to say you are wrong.
