Short:        DiskSpeed & ScsiSpeed for AmigaOS4

This is an AmigaOS 4 port of DiskSpeed and ScsiSpeed 4.2 by Michael Sinz.

Version 4.3 is missing some functionality from the original 4.2 version,
such as the GUI and the CPU usage code.  Both DiskSpeed and ScsiSpeed are
currently CLI-only commands under OS4.  I plan on changing this in the
near future, to add both of those items back in.

Another change is the alignment of the buffers used in both versions.
Code has been added to force the buffer to be 32-byte aligned when
choosing to use a LONG-aligned buffer so that proper measurements of DMA
speeds can be done.  When choosing other tests, like BYTE or WORD aligned,
this will push the buffer off the 32-byte aligned boundary and can be used
to show the performance impact of not using 32-byte aligned buffers.

The CLI operation is the same as in version 4.2, so refer to the old
documentation for usage instructions.  The old documentation is included
without alteration.  One exception is it still includes the WINDOW argument,
but the programs will ignore it should you try to use it.

Please note this archive corrects some issues Stéphane found when he
checked my uploaded file.  I forgot to include a few things, like the
old documentation and the updated SCSISpeed program.  :-)
