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!

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!

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. The excerpt is shown below: AX=000Ch [2.00] Perform final cleanup Input: AX 000Ch DX derivative-specific flags (0000h = clean up all) Output: None Apparently, device is not shut down based on the description of

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

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

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

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.

Hi everyone, I have pushed out Syslinux 3.82 to the usual places. Again, special thanks to my employer, Intel, for letting me spend time working on this stuff ;) -hpa Syslinux 3.82 is a bug fix release for 3.81. Changes in 3.82: * isohybrid: fix the -partok logic for loading from a partition. * ISOLINUX: deal with systems which return from INT 13h with interrupts

Hello, I have a problem with a comboot 16 bits program for syslinux, I use the API openFile, ReadFile and CloseFile for read my own config file. It's ok. I use the int13h to write a floppy disk (syslinux runs on a USB stick), after the first call to int13h, all the call to openFile return an error. Do you know what's the problem? Is it possible to use int13h when we use syslinux API?

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
