Re: Trouble PXE Boot After Kernel Starts Loading
This turned out to be something completely different and, it turns out, something VERY poorly documented.
To communicate with the Soekris system, I need to use a serial cable and the program screen. It turns out that the baud rate is changed during the install unless you specify a baud rate in 3 different places. What was happening was that when the baud rate changed, rather than getting garbage on the screen, I was getting nothing, so it didn't seem like a baud issue.

I added "edd=off" to each kernel line in that config file because it was freezing up with the same message and suspected it was because (as best I know), there is no Enhanced Disk Drive. But then there's the "... ok" after it, which makes me think the edd issue isn't why it's freezing.

I'd rather not have to step back, since that would mean re-doing a number of systems later for updates. While that would not be for a while, of course, I'd like to be able to work from the latest version of Debian possible.
