Re the Iyonix Debian disc access, are you saying that the driver is not
doing UltraDMA at all in any case? This could be one reason that anything
other than the command line is a bit slow. There is a NetBSD for Iyonix
now but I dont think there is any Xwindow stuff done. Either could be
useful for certain tasks even from the command line, but it would be a
shame if the speed was not optimised. TIA -Ron


I have no idea what any other OS uses to access the disc. But if the data
is stored after a 128GB FileCore partition on a 256GB disc as suggested, it
is physically impossible to use UDMA due to the limitation of the
controller.
The 128Gb from start of disc UDMA limit in the iyonix is an ABSOLUTE limit imposed by the ALI chip on the motherboard. Any OS that requires UDMA access speeds should not attempt to access (real-absolute) disc space above the 128GB address.
