This utility interacts directly with an Amiga block device driver to test the
driver and physical device. There are several operation types that the utility
can perform:

* Device probe
* Performance
* Packet support
* Device Geometry
* Data integrity

usage: devtest <options> <x.device> <unit>
   -b                    benchmark device performance [-bb tests latency]
   -B <tsize>[,<#tio>]   set benchmark arguments, default: 512k,4
   -c <cmd>[(arg,...)]   test a specific device driver request
   -d                    also do destructive operations (write)
   -g                    report drive geometry
   -h                    display help
   -i <tsize>[,<align>]  integrity test [-d=destructive] [-dd=no save]
                         [-i=random -ii=address -iii=pattern]
   -k <mode>             integrity test mode: simple or butterfly
   -l <loops>            run multiple times
   -m <addr>             use specific memory (Chip Fast Zorro MB Copr -=list)
   -mm <addr>            use specific address without allocation by OS
   -o                    test open/close
   -p                    probe SCSI bus for devices (unit is optional)
   -t                    test all packet types (basic, TD64, NSD); -tt=more
   -y                    answer all prompts with 'yes'
