similar to: comboot use cases

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

Okay, MediaWiki syntax docs follow. Note I have tested those only a bit, and not within the vesamenu context, but if mboot.c32 resets to

Int 22h AX 001Eh for now as it appears that the COMBOOT API is designed to be strictly sequential. The API gets extended but only implemented (for now) for SYSLINUX in ldlinux.asm.

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 <- ???

hm, nice algorythm thingie. I'm not a programmer, so here goes: currently: F1 helpfile.txt probably results in DISPLAY helpfile.txt perhaps extend this option: F1 arg1 arg2 arg3 argX if arg1 does not exist, abort (currently also done?) if arg1 ends in COM extension, execute it and pass the optional arg2/3/X parameters if arg1 ends in C32 extension, same thing. else DISPLAY arg1 // arg1

Since lot of people want this thing, I will try to take a stab at it. For now, I will hard code the menu in the code, and then somebody else can remove that restriction. May be we can add some kind of keyword to the config file which syslinux ignores and the comboot menu does something with it. I have one question about comboot: If I write a DOS program using C (compiled using watcom -3 -mt -osx

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
