Hi, I've got a question regarding pxelinux: It seems that there is a buck in syslinux 3.86 (or still is in the current build) in the reset_pxe function. If I call "syslinux_local_boot(0)" (in a COM32 binary) the KeepPXE variable is always 1 which resets the PXE stack instead of unloading it: local_boot: push cs pop ds mov [LocalBootType],ax call vgaclearmode mov si,localboot_msg call writestr_early ; Restore the...

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

From: Matt Fleming <matt.fleming at intel.com> Since we can't use __intcall() for EFI, and since we can now have the ELF module code resolve all our symbols at runtime, we should delete as many references to __intcall() as possible and just access the symbols directly. The most interesting patch is the support for weak symbols. We need to be able to reference derivative-specific
