I noticed several issues when diagnosing why pxechn.c32 didn't work in 5.01-pre3. 1) pxechn.c32, prdhcp.c32 and other modules crash Syslinux and force a reboot by executing an unresolved symbols. unload_pxe(), dns_resolv() and pxe_call() are the three. "Error: An undefined symbol was referenced" 2) In past versions, I built a debug build by having "CFLAGS += -DDEBUG=1" in mk/local.mk but this fails. core/../com32/include/com32.h:144: undefined reference to `__bad_SEG'

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

In pxelinux.asm the xchg instruction in xchg ax,ax . data_on_top: should be xchg ax,dx, I think At the end of pxe_get_cached_info routine,there is and ax,ax jnz .err It is supposed to test for AX status, but since pxenv does pushad and popad, AX doesn't contain status. In fact the other routines calling pxenv don't have this bug.

Hello, I'm still trying to setup RIS (Remote Installation Service -w2k) with PXE Linux, but before that I must say that the mail list archive is a _good_ idea. Back to RIS. When I start from pxelinux memdisk initrd=risbootdisk.img I get an error: No UNDI Driver found. The risbootdisk.img is a bootdisk from Microsoft, which starts a RIS installation. When I boot from floppy it works fine,

Hi Peter, I traced over these routines you suggested briefly and I didn't see where it invokes PXE UNDI_API (PXENV_UNDI_SHUTDOWN(0x5) to shut down the device. When this is invoked, my UNDI driver will put the device into an inactive state so that it doesn't do any more DMA read/write over PCIe bus anymore. What am I missing? Thanks!

Hmm... well adding the __export stopped the "undefined symbol" error from showing up when I add "SENDCOOKIES" in the config, however I'm still not seeing any cookies being sent to my webserver. Any ideas on how to further debug? (if you want to send me the debug compile options privately that's okay too) -----Original Message----- From: H. Peter Anvin [mailto:hpa at
