Hello all.

Please cc all replies to me as I am not subscribed to the list.

I recently obtained a SGI Indy.  The hard disk is totally wiped out, with
no OS on it at all.  No IRIX, no sash, no Linux, no nothing.  The machine
has no floppy or CD-ROM drive, but it seems that the boot PROM has a way
of accessing a remote kernel using bootp and tftp.

I want to get linux on this system, but I'm not sure about some of the
details.  I don't have other machines with SCSI interfaces that I could
partition/write to this disk.  Where do I go from here?  I've been trying
to tftp a kernel.. but no luck.  How do i mount a root partition?  NFS?  
How do I partition this box with a SGI partition table if I don't have the
irix 'fx' tool?  Will I have to boot off of a bootp/tftp server
permanently?

Has anyone tried this before?  Had any luck?  Any advise you can give
would be appreciated.

I've been trying to bootp/tftp a kernel with no luck.  I am running a
bootp server on an i386 machine, and it sees the sgi's requests and issues
replies, but the indy ignores them enitrely.


In the following, lestrade is the indy, with IP 192.168.0.105.  hork is
the bootp/tftp server with IP 192.168.0.17.

Here is a transcript of the prom monitor:


>> boot -f bootp()/mips/vmlinux
No server for /mips/vmlinux.
Your netaddr environment variable may be set incorrectly, or
the net may be too busy for a connection to be made.
Unable to load bootp()/mips/vmlinux: could not contact remote server.


Here is output from my bootp server:

# bootpd -v
bootpd+dhcp 2.4.3
# bootpd -d4
bootpd: info(6):   bootptab mtime: Tue May 30 12:20:38 2000

bootpd: info(6):   sending reply (with no options)

my bootptab file:

# /etc/bootptab: database for bootp server (/usr/sbin/bootpd)
# Blank lines and lines beginning with '#' are ignored.
lestrade: hd=mips\
        :td=/usr/local/share/tftpboot:\
        :rp=/usr/local/share/tftpboot:\
        :ht=ethernet:\

        :ip=192.168.0.105:\
        :hn:\
        :to=auto:



If you look at this excerpt from tcpdump, it looks like its working
properly.  I don't see why its being ignored by the sgi.

If anyone can offer any suggestions or explanation, I would certainly
appreciate it.

Thanks in advance,
Chris
