Unfortunately not answering > ARPs has bad effects, too. Etherboot's implementation of PXENV_UDP_READ is and has always been non-blocking. I don't see this problem when I try pxelinux from syslinux-3.08-pre5 and current Etherboot CVS. The relevant routine, pxenv_udp_read() in Etherboot's core/pxe_export.c, hasn't changed since July last year. You can debug this by defining -DTRACE_PX...

Hello PXE folk, I mentioned in another thread that I had problems finding an etherboot that actually works with a 486 and Realtek 8019/NE2000 card. Etherboot worked up until v 5.3.5-mc1 with the ne driver but then stopped working between 5.3.7 to 5.3.13 (anoying since 5.3.7 started supporting PXELINUX. But then I downloaded 5.3.14 and it seems to work again with the ne driver (finally

...oed promptly. C+A+D still resets promptly. I don't know if the problem exists with real hardware, but I do know that syslinux-2.07 was ok on vmware (but that didn't have the arp code, of course). Is this most likely a bug in the vmware BIOS, or is there some timeout we can specify on the PXENV_UDP_READ call? Thanks, Richard

Question for people... Has anyone actually tried running PXELINUX on top of Etherboot? There is something in Etherboot 5.1.7 called FREEBSD_PXEEMU, which seems to be a PXE stack subset, in particular it seems to support the following calls: PXENV_GET_CACHED_INFO PXENV_UDP_OPEN PXENV_UDP_WRITE PXENV_UDP_READ PXENV_UDP_CLOSE PXENV_UNLOAD_STACK PXENV_UNDI_SHUTDOWN This happens to be pretty close to the subset used by PXELINUX, with two exceptions: PXELINUX will also invoke PXENV_STOP_UNDI (for version >= 2.00) or PXENV_UNDI_CLEANUP (for version < 2.00). I'd be really curious to see how thi...

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
