Re: PCEngines APU4B4 doesn't boot AMD64 when PXE is activated in the bios

I stand corrected. Chris, you are right. My humble apologies.

The boot.conf file had wrong file encoding.
boot tftp:/bsd.rd was used, but not the stty and set tty com0 bits
before.
This resulted into exactly what you described.

I could double check the same behavior on the USB key AMD64 boot (where
my tests at 3AM where obviously wrong).
At some point in time I guess that I forgot to type theses instructions
and just draw the wrong conclusions.

Regarding the DHCP issues with iPXE, they have been fixed in the latest
version of the BIOS (4.8.0.3).
I didn't find it in the changelog, but it works properly now.

So, thank you Chris for your help, and sorry again.

I won't make the same mistake twice and rush things, time to go to bed
:-)

'night everyone
