(Tested using a Linux bzImage, with and without an initrd.) Per shuffle_and_boot documentation, %ecx must contain the descriptor list byte length, but it's set with such list end address instead.

Due to limitations of equipment, I have need of using the isolinux boot loader with .iso files generated by roxio. After trying (and of course failing) with an off the shelf version of isolinux, I grabbed the source for isolinux (syslinux 2.11 package) and started looking. It took a few hours to orient myself, but I ended up doing the modification below to isolinux.asm. I then had to write

Hello List, I have below a patch (against Syslinux-1.62), which adds a pseudo-kernel 'swap' which swaps device numbers of the boot device and the first harddisk. It was made for a system equipped with a DiskOnChip (www.msys.com) device which 'steals' the device# of teh first harddisk, This patch is used to enable the syslinux on the DoC to continue booting from the harddisk as if

I created a bootable usb flash with boot menu. One of items was "Boot from hard drive" with command "localboot 0x81". This item worked when this usb flash was prepared with syslinux 6.02. And it stopped working when the flash was prepared with syslinux 6.03. The message was Booting from local disk... Boot error I extracted the source code, investigated, changed, compiled

Well, there are some issues about adding code to syslinux. Mainly there are no space to add code. I propose to move data to 0000:F000 (now in 0000:5000) and font data to 0000:5000 (now at 0000:E000). So we have additional 4K to code. I don't understand however why we have to retain font data... Does EGA card read from system memory all the time?? I don't think so... Perhaps it's better

I am sending a patch that makes the debugging output of PXELINUX slightly more concise, without (intentionally) affecting its completeness at all. Additionally, I am proposing that the debugging output of PXELINUX -- specifically the messages that appear after the copyright statement, but before the menu is loaded -- only be shown in response to keyboard input (such as holding Shift or Alt, or

Hi, I recently ran into an issue where the dependencies generated in modules.dep created a circular reference, which meant that qemu spun forever in modules_load_dependencies(). I did think about detecting this kind of circular dependency at modules.dep generation time but if we ever move to using DT_NEEDED to track dependencies we would need this functionality in the elflink core anyway.

Hi, We're planning to deploy PXELINUX as a primary kernel loader in cluster environment. Problem is that we plan to have IP numbers assigned dynamically while there is no guarantee that all machines has same CPU architecture. This makes IP-based config search algorithm inappropriate for our purposes because we [naturally] expect loaded kernel to match hardware. For this reason I've

Hi, I just pushed out changes that fix pretty much all the compiler build warnings on the elflink branch. Also, I've added "auto extension" support so that if the user doesn't type the file name extension it will automatically be looked up, e.g. now typing "ls" will execute "ls.c32". The following changes since commit

Hi, These patches contain support for some features that are already in Syslinux 4 but weren't working properly on the elflink branch. It's another step closer to feature parity with Syslinux 4. Having to jump through the comboot API for localboot support is less than ideal and I'll eventually fix that, probably when we move a big chunk of code from asm to C. Also, there's a
