	It's boot A/B/filename -flags where A is the TurboChannel slot
number of the device, B is either mop/tftp for an ethernet card, or rzX
where X is the SCSI ID of a device on a SCSI chain. I *do not* know what
the command is for TCDS because it's not supported and no one on the list
has ever mentioned it before. The flags are -a for autoboot -s for single
user (if no flag it specified it will go to single user) and there is one
more that I'm forgetting I think.

	The onboard TC slots on a 200 go like this 7 is the CPU module, 6
is the onboard 10Base2 Ethernet port, 5 is the onboard SCSI. 4 and 3 are
unused, and 0,1, and 2 are the TurboChannel slots that you put add in
boards in (numbered 1,2 and 3 respectively)

	Example auto-booting from an HD connected to a SCSI controller in
TC slot 5, SCSI ID 0 (onboard controller): boot 5/rz0/netbsd -a

	That ought to work, except with 1.5 because mop is broken in 1.5,
tftp should work though.

	Booting from a TCDS is fine, but once you've booted you won't be
able to access it because the TCDS isn't supported in the release code
base. It's working in -current as of a few weeks ago, but no new snapshots
have been made that I know of. You're basically SOL unless someone back
ports the driver to 1.5Release. You'd be stuck with the onboard
Slow-Narrow SCSI controller. There certainly aren't any install kernels
with TCDS support complied in.

	Yes, and it can boot gzipped ELF kernels IIRC.
