I too have this problem (2.0.6) where you get the 'boot:' prompt, you type
the label of the kernel you want to use and when you hit 'ENTER' nothing
If you don't type an option/label and hit ENTER, it boots the default
However I have found if that you do NOT hit enter relatively quickly after
you see the boot: prompt, then nothing happens and you can't even get the
default image to boot.
My hardware is a blade server which has NO video card. Just a serial port.
The BIOS on my server does console redirection to the serial port and stops
the console redirection as soon as the OS starts running. I have noticed
that console redirection is still active while pxelinux.0 is running while
it displays the boot: prompt. You can tell redirection is active because it
constantly refreshes the ENTIRE screen which is verry slow at 9600 :-(
I had a 'SERIAL' option defined in my PXELINUX config file and at first I
thought PXELINUX was getting confused because it was trying to access both
the serial port AND the console but the console was really being mapped by
the BIOS to the serial port. However I still had the problem when I
commented out the SERIAL option.
I haven't had time to try any other version of PXELINUX to see if something
To the developers: Please let me know what I can provide you to help debug
