I thought there was a message detailing the changes I made. Doesn't
appear to be the case (and I can't remember much about it, probably
just a simple dos batch file edit).

Here's the original post, grep didn't turn up anything else in my

I was rather displeased to see that it wanted to repartion/format my
harddrive :-(

I rebuilt it to just load etherboot off the iso image. This only works
for PCI nics, however, no go for old ISA cards. Still it might be useful
