This version contains a fix to mbr.asm, plus a version of Murali's menu system, but ported to gcc. Although gcc produces much bigger 16-bit code (since it's really 32-bit code with prefixes) I figured it would be much easier for people to deal with since it requires the configuration to be compiled in. That being said, it's a *very* powerful menu system, partially *because*

Working on fixing lower-priority bugs that I didn't want to risk destabilizing the 2.07 release for: Changes in 2.08: * Add "timeoutcmd" to allow timeout to have a different action than just pressing Enter. * Fix bugs in the COMBOOT/COM32 command-line parsing. APPEND now works with COMBOOT/COM32 images.

Hi Does subject exist? Is it possible to get MAC address, video card, RAM and the storage of a harddrive by using comboot? And can some one help me? /Kenneth

Hi *, I was just debugging why TFTP booting did not work any more on a system that had pxelinux.0 was updated. ?Since version 5.00, support for 16-bit COMBOOT modules has been dropped, and c32 modules switched from the COM32 object format to ELF.? Ugh. Well, updating the *.c32 files was enough to make the Linux discless thingy work again. BUT! The MirBSD bootloader actually took advantage of

Hi, I would like to use INT22h, function 000Dh, but I found that it is disabled in vector table: in core/comboot.inc: int22_table: [...] dw comapi_err ; 000D clean up then bootstrap [...] The code of this function is present in this file (comapi_chainboot). Why this function is disabled? Regards Piotr Romaniuk PS I am using syslinux-4.04.

Is there a way for isolinux/syslinux to execute a list of comboot files immediately at startup, and only once? I have a bunch of small comboot .com files that I want to batch run immediately, then after that do a DISPLAY boot.msg similar in some ways to an autoexec.bat. For example: DEFAULT mycd APPEND ramdisk_size=100000 init=/etc/init lang=us .... TIMEOUT 300 ONSTARTUP mybatch <- ???

Hi. I want to use PXELinux to build a dynamic boot menu for a computer lab. Sometimes, the machines need to be in Linux mode/Windows mode/allow the option of Linux/Windows. I configured this all fine with PXELinux. My problem is really one of security. Someone can plug in a laptop with a DHCP server, and tftp server and fake a lab machine to boot into any mode they desire, or even

How do I use that in the generic case? The ?pxebsd.0? file can be called as? ? PXE loader ? COMBOOT (16-bit) ? DOS .COM ? Multiboot (although it switches back to 16-bit mode

Hello, Is is possible to run a comboot file before the boot message is displayed and after its execution, display the boot message and prompt? Regards, Remko van der Vossen.

Dear Syslinux developers, I'd like to continue the discussion about this: http://www.syslinux.org/archives/2014-February/021659.html i.e. different directories for *.c32 files of BIOS, EFI32, and EFI64. I am wondering why we can not have *.c32 for the COMBOOT files of BIOS, *.e32 for the COMBOOT files of EFI32 *.e64 for the COMBOOT files of EFI64 As now the ldlinux file of syslinux 6.0x has,

Hi, I've read that Syslinux supports bzImage files now, but when I use pxelinux (which I hope also supports it) with a bzImage, I get : COMBOOT image too large What can I do to fix this ? Kind greetings, Wim Godden

Maybe I missed something here. What I want to happen is PXE boot on a timeout will boot to the hard drive. But, what happens is my comboot menu, which is default, loads right away and the ontimeout only happens when I escape out of the menu. My pxelinux.cfg/default: default menu timeout 100 ontimeout localboot # The Main Menu label menu kernel mainmenu.com append keeppxe #

Hi, I need to add an additional feature to Murali's menu system: sending and receiving UDP datagrams. I have no experiences with writing programs at such a low level. Therefore, I need some help. 1) How to transfer IP address and other options from PXElinux to comboot? 2) I got PXE specification, ver. 2.1 (sept. 1999); can I follow it safely? 3) Is there an easy interface to use PXE stack

Hi, One of our customers uses INT 22h/AX=C to shut down UNDI interface. This interface is documented in http://www.syslinux.org/doc/comboot.txt.

Hi folks, I'm trying to make a CompactFlash bootable with SYSLINUX. The hard part is that I'm trying to run SYSLINUX on Windows 2000 and am attempting to write to the compactflash that's plugged in via a USB reader/writer. Its not working -- Windows complains about the 16-bit subsystem wanting direct access to the drive. So then is the problem SYSLINUX fighting with Windows or

I just found a rather embarrassing bug in PXELINUX -- and what's worse -- I wrote an email about it and killed it off accidentally :-/ It appears PXELINUX doesn't free its internal socket buffers (it has 32 of them) when it gets an error reply from the server, including "file not found." This means it will eventually run out of sockets and "go deaf." This

I'm going to make an experiment with redirecting the main webpage to the wiki for a while. I hope to make this permanent. In order to make this stick, I would *greatly* appreciate any help in spotting and fixing stuff that is out of date. Thanks! -hpa
