If a syslinux floppy does not contain a config file (syslinux.cfg) modules are not being found unless specified with a directory prefix (e.g. /pcitest.c32). The reason is that CurrentDir is only set if there is a config file present. This is a possible regression since commit 68eefb79e2cbb590ebf958dd0c50ce00b941abd2. Before this change RootDir was used in searchdir and now it's CurrentDir

Hi folks, I've got a problem with COMBoot (16 bit) in SYSLINUX 2.06: while the write string call (ax=2, int 22h) works just fine, the open file call (ax=6, int 22h) does nothing at all. Calling that function doesn't modify any register, and doesn't modify the carry flag. I then modified comapi_open in comboot.inc so it sets ax to some value and recompiled SYSLINUX, reinstalled it

Hi folks, I'd like to write a graphical menu for a rescue Linux system I'm currently working on in my spare time. I'm experimenting with VESA for this... but my real questions are: How do I boot a Linux kernel from a COMBoot (.cbt) program ? Supposed I have syslinux.cfg that looks like this: DEFAULT menu LABEL menu KERNEL menu.cbt LABEL linux KERNEL kernel.bzi Do I have to use

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.

Hi, We are using pxelinux at my company to test our product. And there are limitations that we have hit in the past w.r.t. the max length of a path, or the max length of a module name (in mboot.c / mboot.c32). We've used workarounds in the past, and reorganized the directory structure, but we face that problem again. Out of the 128 / FILENAME_MAX chars that can be used, 110 - 120 go to the

Hello Gurus, I'm using one of the function, i.e. extractModelParameters, from the MplusAutomation package to read parameters fromMplus out files into R.

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

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 <- ???

This is the latest version of the gfxboot module. It's supposed to work on all Syslinux derivatives.

The BSD kernels are normally loaded by their own BSD-specific bootloaders (although some other bootloaders can, with
