Re: [9fans] CDROM boot failed, how can i do?

[River He]

Thank for your help.

I burn plan9.iso to a CDROM, when it prompt "boot form:"
I typed as below:
sdD0!cdboot!9pccd.gz
but it display:
unknown partition sdD0!cdboot
and return to
"boot from:"

why?

Re: [9fans] CDROM boot failed, how can i do?

[andrey mirtchovski]

because 9load cannot find your cdrom drive. as others suggested:

	- try switching its place -- if it's on the second ide slot move it to
	  the first, if on the first -- move it to the second
	- try it without the hard drive in
	- try a floppy disk

experiment.

the documentation is on the plan9.bell-labs.com/plan9dist web page, see
Papers, Man pages and Wiki.

I agree with the "experiment" part, my suggestion would be a lot more
organized with your approach than others would suggest. I'd say -never-
put your CD drive as a slave on a EIDE (or IDE for that matter), unless
you're sure you'll -never- want to boot from it. I'd suggest strongly that
if you put your CD on master and your HD on the slave and it still doesn't
see the CD drive then get another CD drive. There are some problems with
some drives (I've got a pile of about four drives that don't work). I just
replaced the drive in saucer.ssz.com with a DVD/CD burner and it worked like
a champ (the 40G drive helped a lot too).

As an aside, Rob and I have been working on a new install doc that makes a
lot more sense than the stuff on the Bell Labs site, too much work
scattered out over too many documents.

http://einstein.ssz.com/hangar18/Plan9Intro.txt

This doc is -not- finished so don't expect it to solve all your problems,
yet ;) However, you can expect to see new sections added at least weekly
as Rob and I get windows of op to move forward.

There shouldn't be any problem booting from any IDE position.
There can be a significant loss of throughput if the faster
of the two devices on a slot is not the master.

I must say that the whole "PC" disk/boot/partition
situation is one of the ugliest messes I've seen in
my 40 years of computing.  *The* major contributor to
this is the rush to market with "any old solution" no
matter how short-sighted, leading to kludge upon
kludge as newer developments outgrow the older,
unnecessary, limitations of the interface designs.

However, the fact is there -is-. I've seen this on Windows, Linux, Plan 9,
Unununium, etc. So have many others over many years, it is not a new
problem by any means.

If you want to minimize the hassles with CD's then always put them in as
the master.
