I'm trying to add boot support to https://github.com/libguestfs/nbdkit/tree/master/plugins/floppy This NBD server plugin generates a completely virtual FAT filesystem and partition table. Nothing is ever written to a file, and it must run without anything needing to be root, loop mounting etc. Running "syslinux --install <something>" is a non-starter. So I've looked at

Hi, This AMD Elan board seems to be very problematic: http://www.embeddedarm.com/products/board-detail.php?product=TS-5500 I'm having various issues with booting recent Linux kernels with syslinux. syslinux-2.13 was the last version that worked and since syslinux-3.00 it doesn't work. When it doesn't work all I get is "Boot failed" from the bootsector. Since the obvious

I'm working on a debugging/diagnostic image in order to debug/diagnose an issue with very recent machines using a UFD (USB Flash Drive) which really _should_ be partitioned but someone decides to be a little too quick and uses it raw. (FAT* file system on /dev/sdb rather than /dev/sdb1). Anyways, I've got a successful first iteration that'll say what the BIOS thinks about geometry and

git://git.zytor.com/users/genec/syslinux.git Branch core-diskstart-chkerr-for-hpa verify_checksum is built to allow for segment wrap (ldlinux.sys larger than 33280 bytes if my math is right). If the wrap occurs, DS is no longer 0. If there's a checksum error after DS is no longer 0, it won't be able print checksumerr_msg properly. 2 commits: 1 to make the fix in verify_checksum; the

Hi! It's indeed better to open a new thread for this. So, here's my test session: $ qemu -fda extlinux.144 -s -S Then in another terminal: $ gdb extlinux.elf (gdb) set architecture i8086 (gdb) target remote localhost:1234 Remote debugging using localhost:1234 0x0000fff0 in ??

Hi guys, I'm have a pure 64-bit system (Intel based). Due to that I can't use 32-bit ELF extlinux binary provided in the syslinux-6.03 package. Unfortunately building extlinux installer failed...

After so much time and improvements, I'm glad to see and publicize a pre-release, 6.04-pre1 in https://www.kernel.org/pub/linux/utils/boot/syslinux/Testing/6.04/ Personally, I've already been working testing the pre-release as-is and my tests have been positive so far. I appreciate feedback like that from Gabriele Balducci and testing "make bios installer". Yes, there are a

From: Matt Fleming <matt.fleming at intel.com> Here are the patches that I've got queued up based on the very helpful feedback I received from people testing Syslinux 5.00-pre9. Unless anyone has any concerns these will make it into Syslinux 5.00-pre10. Matt Fleming (9): pxe: Don't call open_config() from the pxe core ldlinux: Print a warning if no config file is found

I need to debug some issue in second stage of syslinux boot, i.e. ldlinux.sys. I have put a few debug instructions in core/diskstart.inc and recompiled everything. The newly obtained ldlinux.sys confirms to the size restriction for the boot sector. Now how do o replace the current /boot/ldlinux.sys file with mine. I tried removing the immutable flag and then doing a copy. Nothing changes. It
