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

Running "syslinux -s /dev/dsb" during installation of Slackware64-14.1 (to make a bootable USB stick) fails like this: Error converting to codepage 850 Invalid argument Cannot initialize 'S:' Bad target s:/ldlinux.sys syslinux: failed to create ldlinux.sys But running the same command in the installed system succeeds. In both cases we are using syslinux-4.0.6 (same syslinux

I think there may be a misunderstanding here. Are you saying that when installing ldlinux.sys + ldlinux.bss v5.01 on a FAT filesystem, the installer needs

Goal: To have one USB drive capable of booting UEFI IA32 and UEFI X64 (with an optional Syslinux menu containing multiple entries). Problem (solved) #1: The default directory location for both syslinux.efi is the same. Solution #1: Rename each syslinux.efi to bootx64.efi and to bootia32.efi. Problem (solved) #2: Each syslinux.efi needs at least its respective ldlinux module. Solution #2:

After formatting a floppy to MSDOS format and using syslinux /dev/fd0, I successfully installed ldlinux.sys to the root directory of the floppy. Then I created a syslinux.cfg under the root directtory of this floppy to load the linux kernel in my first hard disk, 3rd partition, boot folder. The file system of this partition is ext3. The floppy has a FAT file system. This config file is listed

Thanks for responses. I use GRUB as my bootloader in my hard disk now. I have a Windows in sda1, Ubuntu in sda3. If I want to install extlinux to boot Ubuntu, should I follow the steps below? 1. in Ubuntu, go to extlinux folder, run command ./extlinux --install /boot 2. create an extlinux.conf in/boot 3. cd ../mbr 4. cat mbr.bin > /dev/sda (or use dd if=mbr.bin of=/dev/sda bs=404 count=1)

Hello syslinux list, I have installed Arch over a btrfs-formatted dos/MBR primary partition* (no btrfs subvolumes, just installing everything including /boot in the root of the btrfs). I have been unsuccessful for several days trying to get it to boot with syslinux (6.02-8 package from Arch, also tried 4.07-1 Arch package). All I am getting is the copyright header line and a blinking cursor

Hello, today I upgraded from Syslinux 4.06 to to Syslinux 5.00. But now the system won't boot anymore and I get the message Failed to load ldlinux.c32 Boot failed: please change disks and press a key to continue What I have done: 1) Installed Syslinux 5.00 2) Reinstalled "mbr.bin" to /dev/sda and /dev/sdb using dd bs=440 count=1 conv=notrunc

>From the current pathbased branch, linux/syslinux.c, line 421, open() yields an error on a FAT floppy image, 2.88M standard size. At first, this was a floppy that did have a previous version of SYSLINUX installed. I saved that floppy image and tried deleting ldlinux.sys with the same results. I'm still trying to drill away and find more about its status and understand what is

Hi, So far I use the official binaries to boot an USB installer in UEFI and BIOS mode. I want to add a (recent) MacBooks target. I know that needs to set up on the device an HFS+ partition with a specific layout, but my question is: do you know if the official binaries: $SYSLINUX_SRC/efi64/efi/syslinux.efi $SYSLINUX_SRC/efi64/com32/elflink/ldlinux/ldlinux.e64 work in that context? Best

It's needed to enumerate both UFS1/2 since they have different magic numbers and super block offsets. Besides, UFS2 can be installed in the 0-64k range like BTRFS, whereas UFS1 can't.

I have some concerns about the Syslinux boot process, which I'm now investigating in connection with my work on booting Live-CD images from USB flashdrives. Some of these are related to what seems to be inadequate documentation, but I think that there are also aspects of Syslinux operation which could be fairly easily improved. quoting from the official documentation: Since version 5.00,

Hello Gene, thanks for your reply. Yes BIOS mode. The config wants a menu, which loads fine under ext4 and not under btrfs. Under btrfs I have also tried to remove the syslinux.cfg file altogether (which should trigger the boot: prompt if I am not mistaken) and the result is the same: only the copyright line appears and no prompt. The three letter sequence is EDD. The disk is 160GB, here is the
