Re: [9fans] plan9v3 won't start (PBS...Bad format or I/O error)

["Russ Cox" <rsc@plan9.bell-labs.com>]

If it installed its own MBR there should be MBR...
before PBS...  You may need pbslba instead of pbs.
That is,

	disk/format -b /386/pbslba /dev/sdC0/plan9

Or maybe you already have pbslba and you need pbs

	disk/format -b /386/pbs /dev/sdC0/plan9

(it will just install a boot sector, not format).

	And something more: is it possible to use history
	and command completion with rc?

Not really.  I like this command (which Tom Killian
introduced me to) a lot though:

	g% cat /usr/rsc/bin/rc/"
	#!/bin/rc
	
	{
		if(test -r /mnt/acme/acme/body)
			cat /mnt/acme/acme/body
		if not
			cat /dev/text
	} | grep '^[^ 	]*%[ 	]*'$1  |
		{echo; cat} | pr -t -n | sort -u +1 | sort -n |
		sed 's/^ *[0-9]+	//' | grep .
	
	# the silly {echo; cat} gets around pr printing "empty file" when
	# presented with no input.
	g%

It prints all commands in the current
window that begin with the given string.
For example, it prints the two lines marked with >>>
in the following.

	g% cat /usr/rsc/bin/rc/"
	...
	g% cat /adm/users
	...
	g% " cat
>>>	g% cat /usr/rsc/bin/rc/"
>>>	g% cat /adm/users
	g%
