similar to: SYSLINUX API call INT 22h/AX=0xC

Hi Peter, They use PXELINUX to download the OS deployment bootstrap. When this is completed, they want to shutdown the stack including the UNDI driver before jumping to the kernel. Thanks!

I have a Dell 1435 system that will not respond correctly to a com32 call to Local boot Int 22h AX=14h DX = 0 This call should not return. It should unload the PXE+UNDI stacks and continue the boot process with the next boot device. This call is working fine for me on an HP DL360G2 and on a Dell PE 850. But, on this Dell 1435 the call is returning from the Int 22h. I am using syslinux 3.51

Hi Peter, I traced over these routines you suggested briefly and I didn't see where it invokes PXE UNDI_API (PXENV_UNDI_SHUTDOWN(0x5) to shut down the device. When this is invoked, my UNDI driver will put the device into an inactive state so that it doesn't do any more DMA read/write over PCIe bus anymore. What am I missing? Thanks!

comboot.txt says to set CL=9 "to get a valid return in CL for all versions". The code in __syslinux_get_derivative_info() doesn't set it. Is this comment obsolete? Looking at comboot.inc suggest this because P_CL is set to SECTOR_SHIFT for all derivatives but pxelinux which does set P_ECX to MyIP. - Sebastian

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 already a way to read directly from the disk, perhaps via INT22/19h, using the COM32 open()/read() functions? If not, I'd like to propose adding the ability to do something like: int fd = open("//", O_RDONLY); to allow reading from the raw disk. I am working on building a COM32 module out of the checkisomd5 tool from isomd5sum, but I need a way to access the raw disk in

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'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

sorry - i must have overlooked the part where you mentioned that.. my fault. What software are you looking at ? Altiris maybe ? I am, ofcourse interested in the option you are looking for. Please keep this list updated.

Ok, here is the first try to turn the gfxboot wrapper into a com32 module. I had to extend the interface to the gfxboot core a bit to get it working.

Can't hold it off any longer... here it is :) Changes in 2.00: * ALL: Add support for "COM32" (32-bit COMBOOT) images. * ALL: Add an API for COMBOOT/COM32 images. See comboot.doc for details. There is a C development environment for COM32 being created; it should be ready at some point in the future. * Fix mbr.asm so that it

Hello syslinux mailing list, I've been working on a kind of system administration tool ( http://twyna.sourceforge.net/) with a colleague of mine for our Computer Science Bachelor degree internship. I hope I'm saying that right :) We use gPXELinux to boot over a web service and it's all working marvellously, except for the localboot bug. Until now we've used chain.c32 to solve

So here it is. Ugly and far from acceptable shape but nonetheless it seems to work. Parts are borrowed from syslinux core and of course the gfxboot patch for syslinux 3.63.
