telnet (root)It doesn't look like you tried to mount the real boot flash.
mount /dev/sdb1 /mntIf that works, then try
ls /mntYou should see something like this:
csums.md5 kernel.up root.tlz version.txt
initrd.gz ldlinux.sys supplmnt.tlz vpd
kernel memtest syslinux.cfg
Let us know what you see there.

I'm not sure if the vpd showing in in the root in Sandshark's guide is a folder, or whether it is the vpd file itself. I'm tagging him, so hopefully he will answer.
