I looked through the archives but I didn't see much current on the
subject (esp. under 4.0).
I have two different machines, both with AsusP5A motherboards and
Western Digital Caviar hard drives that should support UDMA/33, as should
the Chipset.
Both boot up, trying UDMA mode, throwing ICRC READ ERROR's then kick back
down to PIO mode 4.
They each have _different_ Caviar drives, one's running 66 MHz on the
motherboard (older K6/2-300) the other 100 MHz (newer K6/2-450). FWIW,
the Sony DVD-ROM in the latter machine also dislikes running at DMA
mode.
Bios's are set to do auto-chose pio/dma modes.
I've resolved to simply adding in the rc to reset them to pio mode, to get
it over with (but I still get the errors at boot-up prior to the rc doing
them).
I simply use 'device ata' etc. forms in the knerel config.
Thanks
