Hi Josh,
[ I added Etherboot-Users to the list for wider distribution. ]
This looks like a great tool!
ftp://ftp.scyld.com/private/jlehan/pxe-on-a-disk.html
A Universal PXE-on-a-disk floppy is a really neat thing. I have read
the thread on the SYSLINUX list, and see how it differs from:
http://etherboot.anadex.de/
Which is another neat tool.
Thanks so much for doing this. I would like to continue discussion
of the outstanding issues that you mention, and maybe we can make it
even better.
I think that there are a few people on the lists that may be able to
help debug the EM64T issue.
Is there any chance of a hardware donation we can offer to someone
who is willing to figure it out? We can also offer a small cash
reward (although Eternal Glory may be enough ;)
In any case, thanks very much for your work! It's a nice tool, and I
encourage you to keep polishing it. It might be something to
consider putting on the Etherboot web site.
Everyone who can, please test this tool, and send your findings to
Etherboot-Users.
Thanks,
Marty
