??? The above should go into the kernel options line of the booter, in
case I didn't make this clear before. "54 not understood" is nothing I
would expect the kernel to issue.
i interpreted this exactly that way. the message comes from the scsci
controller. the controller is recieving commanf code 54 which besides
being an optional command (not part of the standard list) is not even
appropriate -- - 54 is for a cd/dvd-r drive not a hd.
my impression thence is that maybe the kernel is not even using the
correct driver, at all. since it does not follow the current standard of
using modules, there is not easy way to check, load, unload drivers
as there would be with a sane initrd. that is to me one of the goals
of etch, why there are two replacement candidates for mkinitrd and
a new format besides.
with command codes at controller level scrambled , anyway no
wonder that directories get corrupted.

The bus is reset on booting Linux anyway.
sorry. i guess it is the controller, not the bus.

HD SC Setup and the like are only required to place driver partitions on
the disk. After that's done, you can partition using Linux tools (I
haven't used parted but I'd hope they leave the driver partitions and the
general ordering of entries untouched).

Drive Setup 1.7 perhaps does not install 68k drivers anymore.
only for '040

Any improvements on the ADB front there?
my impression also until i hear otherwise , there is NO mac II / 68030
support in etch/2.6 kernels. at least not until quadra/040 has been good
for a while, supporting more machines.
