Hi Peter Anvin I tried to use open file and read file SYSLINUX API. But it always make my PC104 freeze. My snip code : ================================================ int __start(void) { int ax,cx,dx,es,si,di,t; com32sys_t inreg,outreg; memset(&inreg, 0, sizeof inreg); memset(&outreg, 0, sizeof outreg); strcopy(__com32.cs_bounce, "test.txt"); inreg.eax.w[0] = 0x0006; //

Hi Peter, Please pull the following changes. Paulo, I had to revert your "pxe: resolve names via DNS from protected-mode code" change because dns_resolv() is only implemented for PXELINUX and causes undefined symbol references for ISOLINUX, etc. Feel free to make the change again on top of the revert. The following changes since commit e7bd19def830e8341b1a100956345f1028740b9e:

Hi, I've checked the archives for my issue, and while there is relevant discussion, the problem the original poster was asking about didn't seem to have been resolved then either (~2 years ago). At any rate, basically what I'm trying to do is send (possibly receive) UDP packets via the PXE stack using the com32 API (using version 3.11 of syslinux). I have followed both the comboot

(sorry for my english if it is approximate !) I want to access harddisk from com32 api with PXELINUX. I try to use int 13h Extended Read Drive Parameters (48h), it doesn't works. Here is my code, I have an error 1 in AH return code. Int 13h Read Drive Parameters (08h) work well. ******************************************************************************************* struct params {

Hi everyone. I've read through the archives and found a few posts about using the PXE stack, but none of these really helped me. What i want to do is: Prompt the user for 2 values, desired hostname and a "pin" (just a number) and send this information over UDP to my server The problem is not the user input but the UDP part. I've tried to change the code from the post of jesse

From: Matt Fleming <matt.fleming at intel.com> Since we can't use __intcall() for EFI, and since we can now have the ELF module code resolve all our symbols at runtime, we should delete as many references to __intcall() as possible and just access the symbols directly. The most interesting patch is the support for weak symbols. We need to be able to reference derivative-specific

I'm seeing this on a HP Blade and i'm not sure why this is happning since the nature of the issue is so wierd. I compiled mboot.c with a DEBUG defined in the mboot.c file. In the funciton init_mmap(), it prints the e820 map and on the HP blade this map values come out to be totally random. Some weird numbers which dont make any sense at all. However, if i add a while(1); or a exit(1); at

Hey, Looks like read disk function which was launched in 3.35 isnt working. Did anyone test this on any hardware? I'm using it thru the com32 interface to read contents of the active partition of a USB boot key (syslinux). I did a sample test like: void scanAndPrint() { com32sys_t regs_in; char *sectorBuf = __com32.cs_bounce; int i; memset(sectorBuf, 0x0, 512); // XXX MARK 1

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 Peter, The main part of this pull request includes commits that try to replace as many __intcall() invocations as possible. Some remain, but not many (and eventually they'll be gone too). There's also a patch to make better use of ld's --as-needed option and various other bug fixes/cleanups. The following changes since commit ff7334a2ce536b7f4b1f6d6f93ff4e285a3bd45a: Only

Hi all I've written a basic COM32 module that checks (using the DMI example code) the product and BIOS and if the BIOS is not at the required level, is supposed to exit and boot using a DOS floppy image to flash the BIOS. The problem is that I can't work out how to call the DOS floppy image. Looking at the website, I see "Run Command" AX=0003H via int 22. The image name will

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

New module which check if the PLoP Boot Loader already has booted a CDROM or USB drive by checking for the presence of the PLoP INT13h hook. The following assembly code (NASM) can detect the PLoP INT13h hook: mov eax,'PoLP' ; Reverse of 'PLoP' mov ebp,'DKHC' ; Reverse of 'CHKD' int 13h cmp eax,' sey' ; Reverse of 'yes ' jz

Hi folks, Syslinux 5.00 is out in time for the holidays. This release includes a lot of changes from 4.06. I've included the NEWS entries below, which highlight the major changes. Lots of assembly code has been rewritten in C, which makes further development much easier (and also really helped for the 'firmware' abstraction that appears in Syslinux-6.00-pre1). So be on the lookout

Fix breakage in the "hide" option support patch: - The code which initialized the global variable "dapa" was lost in commit 81c203f2, therefore EBIOS access did not work properly. Fixed by removing the global variable completely and moving all bounce buffer handling into read_sector() and write_sector(). - write_sector() copied data to the bounce buffer, but then
