What would cause Installation Disk 1 to try installing
the files to the floppy disk instead of the hard disk?
This is what it seems to be doing in my case.

The hard disk is configured as follows:

	Partition 1	Non-Dos		29 Meg
	Partition 2 C:	Primary DOS	300 Meg

	Total Disk Space:	420 Meg

The first partition is there because the computer
is used as a network client.  I created the second
partition to install Plan 9 onto.

Er, I seem to recall that during the install, Plan9 writes some
configuration details to Floppy #1 - In fact I recall a note somewhere
about making a backup copy of floppy #1 ..just in case...I hope this is
not off the subject & helps?

The reason that I figure it is trying to install to itself is when I
write-protected the disk, I got I/O errors during install.  When I made the
disk writable, everything seemed to work fine but nothing was on the hard
drive.

i *doubt* that the floppy is trying to write to itself -- it reads alot
during boot, it's all reading, though.

if the installation isn't getting up to (or past) "...put 1.2Mb on your
disk..."  i would think it's because it can't deal with your disk partition
set up.

it makes sense because the first stage of the install (into C:\PLAN9) is
just a step towards installing into it's own partition, which you don't
have.

i believe you have to have (maybe the *lowest* partition, i dont know) a
DOS partition *and* a free partition in the high end of your disk, in order
to begin any of the installation.

it expects the DOS partition to start the disc.
it tries to mount /dev/hd0disk (inter alia) on /n/c
but if that fails, it continues, and since the
empty directory /n/c was left writable on the installation floppy, it writes the files there until
it runs out of space.
