[9fans] Boot Error (more)

[Mark Bitting]

I reentered the installation procedure, and made a boot floppy.  Everything
boots fine from the floppy, but booting from the hard drive still fails with
the I/O error.  Any ideas on how to fix it, or should I just keep the floppy
in all the time?

The source is in /sys/src/cmd/wikifs.
Have fun.

The simple use is the main reason why I dl'ed Plan 9, it's the nicest wiki
I've ever seen.  (The adventure in Plan 9 is a bonus)  The non-computer types
can use it, unlike some wikis that require a masters in CompSci to use.  Any
hints on where I could go to butcher the code to add an image tag would be
appreciated.

There is (intentionally) no way to put images
on the wiki.  The reason I didn't use one of the
common wiki packages was I wanted something
that could be easily edited and viewed both on
the web and in Plan 9 (meaning acme, as it turned
out), so it's only text.  That's the reason the
markup is so simple -- acme users see exactly
what the HTML edit box shows.

Same old same old... the box is only about a year and a half old.  I have an
antique Dell P166 that works fine, running a wiki from a basic terminal
configuration.  I wanted to set this box up properly and move the wiki to it.
 Looks like the floppy is gonna be a permanent fixture, if it'll work for a
cpu server, cool, I can live with it.  I'm not going to be rebooting it
often, it'll just be running forever serving an httpd wiki.  (and is there
any way to put images on the wiki pages?)

if this is a particularly old computer,
perhaps it would work better to use

	disk/format -b /386/pbs /dev/sdC0/9fat

i was thinking that maybe your plan 9
partition was too far into the disk, but
it's the only thing on the disk, so that's
not it.

I tried it a second time after a disk/kfscmd allow, and got the "used 0
bytes" message again, also did the mbr thing again, it still won't boot from
the hard drive.  More hd info from the bios output:

Re: [9fans] Boot Error (more)

That's useful.  Try booting from your floppy,
then at a shell prompt type

	disk/format -b /386/pbslba /dev/sdC0/9fat

It won't actually format your disk, just install
a new boot sector.  (Make sure you include the
-b flag.)  I'd be interested in the output of

	cat /dev/sdC0/ctl

by the way.

Thanks.

It spits out the AMI BIOS configuration table, followed by:

SDRAM  at DIMM  #    :  1
Searching for Boot Record from Floppy..Not Found
Searching for Boot Record from IDE-0..OK
MBR...PBS...I/O error
Press a key to reboot...

That's it, no real clues about what it doesn't like.

Hardware is:  Celeron 500, 64MB RAM, 10GB hd primary master (all Plan 9, no
other partitions for anything else), PS2 mouse, USB disabled in BIOS (which
may or may not really mean anything), 3com 3c905 ethernet card, Tean TN2
(Cirrus CL-GD5440-J-QC-B) video, 3-1/2" floppy drive, generic keyboard, and
nothing else.  The box booted Linux and FreeBSD without complaints in its
past lifetimes.

Can you send all the output that gets printed
when you try to boot from the hard drive?
