I have reason to believe that an odd box that is having boot trouble has three instances of "!PXE" in the chunk of memory that "Method D" should look at. I thought I would try to find out how pxelinux copes with this, by trying to insert printfs in pxe_init, but nothing gets printed. I can spew lots of output if I set DEBUGOPT = -DDEBUG=1 -DDEBUG_STDIO -DCORE_DEBUG=1 but given that this box doesn't have a serial port, anything I add will whizz off the screen. >From looking at com32/include/dprintf.h, it looks as though all this does is to...

...mory that "Method D" should > look at. 1) You can't have 3 instances in the same place. You might have 3 that are overwriting each other. 2) Method D is quite the fall back. > I thought I would try to find out how pxelinux copes with this, by trying > to insert printfs in pxe_init, but nothing gets printed.

I am sending a patch that makes the debugging output of PXELINUX slightly more concise, without (intentionally) affecting its completeness at all. Additionally, I am proposing that the debugging output of PXELINUX -- specifically the messages that appear after the copyright statement, but before the menu is loaded -- only be shown in response to keyboard input (such as holding Shift or Alt, or

From: Sylvain Gault <sylvain.gault at gmail.com> Despite having native network capabilities, UEFI 2.4 (the most widely deployed at the moment) has no native DNS resolver. I propose here an implementation more or less inspired by the one found in core/legacynet/dnsresolv.c. Since it's non-trivial, I'd like to ask for a deep review of this code. I tried to make it as strong as
