Hi, For some time now I have been using pxelinux to add a helpful 'administrator' boot mode to our workstations with the following 'pxelinux.cfg/default' config: ---- DEFAULT local PROMPT 0 TIMEOUT 0 TOTALTIMEOUT 1 ONTIMEOUT menu ALLOWOPTIONS 0 NOESCAPE 0 LABEL local LOCALBOOT 0 LABEL menu CONFIG /pxelinux.cfg/default-menu ---- This is great as by

From: Matt Fleming <matt.fleming at linux.intel.com> This series fixes some bugs and switches the elflink branch to be entirely ELF modules. It applies on top of, http://syslinux.zytor.com/archives/2011-April/016369.html The deletions in the diff stat below are mainly from deleting com32/elflink/modules (finally!). Now there should be no duplicate code because we don't need COM32 and

Hello all, We're having the following issue: when in UEFI mode, any output/errors from a lua script is invisible! This occurs even just running 'lua -v'. It runs and returns to a (visible) 'boot:' prompt, but there is simply no output visible from lua! (It does do a linefeed, but no visible text appears.) Has anyone encountered this? And/or know of a solution? For

I'm working on (re-) implementing serial console support in virtualbmc [1], and one of the issues I'm hitting right now is that after establishing a console connection via... self._stream = self._conn.newStream(libvirt.VIR_STREAM_NONBLOCK) self._domain.openConsole(None, self._stream, 0) ...I can't figure out how to close the console. Subsequent calls to openConsole fail

I still agree. But while answering Ady's questions i get to a question of my own: Do all six fixed isohdp*.bin variations still fit into 432

hi,all 1.how to use openConsole and openGraphics? 2.what is the theory of that? thanks

Hi. I've ever wondered how nuch timeis left to timeout while waiting at the boot prompt, so I've writen this small patch to show it. This add a configuration command 'showtimeout'. If you like the patch I could improve it (for example to show the timeout in decimal because now it uses the writehex functions) Regards. -- ______ ________ / / \/ /___ ) I N T E G

New module which check if the PLoP Boot Loader already has booted a CDROM or USB drive by checking for the presence of the PLoP INT13h hook. The following assembly code (NASM) can detect the PLoP INT13h hook: mov eax,'PoLP' ; Reverse of 'PLoP' mov ebp,'DKHC' ; Reverse of 'CHKD' int 13h cmp eax,' sey' ; Reverse of 'yes ' jz

Hi again. I was just wondering if there are any support for running programs inside a VM through libvirt. From what I can see in the API the only solution I found was connecting to the VM with openConsole and running the program I want. This however seems a bit tricky through Python and I was just wondering if there are any simpler solutions. Best regards. J?rgen -------------- next part

git://git.zytor.com/users/genec/syslinux.git Branch core-diskstart-boot-for-hpa. I found that INT 13h AH 08h in BOCHS used ES, DI, at least when using a partitionless HDD, causing "Boot error" from the magic check as it was loaded to the wrong location. HPA suggested wrapping INT 13h with the push/pop for ES's safety. This then lead to checking over for all int 13h calls in

Hi Peter, The main part of this pull request includes commits that try to replace as many __intcall() invocations as possible. Some remain, but not many (and eventually they'll be gone too). There's also a patch to make better use of ld's --as-needed option and various other bug fixes/cleanups. The following changes since commit ff7334a2ce536b7f4b1f6d6f93ff4e285a3bd45a: Only

OK, 6.01 is now out. The main intention of this release was to fix the terrible bug in Syslinux 6.00 which made it impossible to boot kernels from BIOS. This resulted in a way shorter than usual release cycle, and it does mean that there are some bugs that have been reported that haven't yet been fixed. Shortlog appended below. Thanks to everyone who helped test things out. --- Gene Cumm

Hello, I create simple script based on virt-resize as example, and I want to copy freebsd installation between vm's http://pastebin.com/ZK7Bg6FQ At boot I receive error "Missing operating system".

From: Matt Fleming <matt.fleming at intel.com> The first two patches in this series are fixes for bugs reported by someone in #syslinux. The third makes dmitest.c32 actually wait for user input. If no one has any objections/concerns, I'll pull this into the official elflink branch. Matt Fleming (3): core: Print error message if we don't load ldlinux.c32 Clean up $(GPLLIB) leak

From: Matt Fleming <matt.fleming at linux.intel.com> These patches are based on the elflink branch. This set of patches is my attempt at moving the command-line interface functionality out of the core and into an ELF module to reduce the size of the core. The most interesting patch is [PATCH 4/4] which moves the cli code out of core/elflink and into com32/elflink/modules. [PATCH 4/4] is

Dear all, I'm trying to boot a recent PXELINUX on a brand new Soekris net4501 (comBIOS 1.33). This combination appears to not work out of the box... I see much advice floating around from a few years ago, hinting that earlier versions of PXELINUX might have worked. However before resorting to archaeology I'd be interested in feedback from others who might have got through this. I

Hi all, I have released SYSLINUX 2.12-pre1. This version has an initial version of libcom32, a small C library based on klibc for writing com32 programs in C. It is far from perfect yet, but it should be a lot easier to use than hand-coding everything. As usual, find this stuff in: ftp://ftp.kernel.org/pub/linux/utils/boot/syslinux/Testing/ -hpa
