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

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. pxe_unload seems to be never called; if so, also Real...

Hi I have made myself a derivated menusystem based on the complex.c menu that cames with syslinux. And now I need to read a file, search for my pxebooted netcards mac address, and write some changes back to the same file. All the writing and reading I hopes will be of no trouble, but how can i find my own mac address? (and IP adress would be nice). I have searched the list, but I really cannot

...ave experimented with the ALTERNATE TFTP SERVER mechanism described in pxelinux.doc. I observe that it allows me to pull a bootstrap from another tftp server. Using this mechanim, I can successfully load pxelinux.0 from globalTftpServer. However, it does not have the desired results. pxelinux uses PXE_GET_CACHED_INFO to get the DHCP packet to find out where the tftp server is and what file to boot. So, I can load a new pxelinux.0 from globalTftpServer, but it still uses the pxelinux.cfg on localTftpServer (since that is where I booted from). Q: Is there any trick/mechanism to get around this and nudge my '...

Hi all I'm trying to resolve a problem that's recently popped up by turning on auxillary VLANs for our Linux workstations. The problem shows as DHCP failling for anaconda (but always succeeds for PXE). I tried adding 'ipappend 1' to the pxelinux config files but had no joy. I'm thinking that if I write a COM32 module that adds "ip=1.2.3.4 gateway=1.2.3.1

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
