Hello, I am trying to boot the extracted contents of an iso, on a usb stick, using the bootsect.bin included in the iso. Yet it will not work. the bootsect.bin file is in the root of the usb drive, as well as syslinux's cfg file. Here is what the cfg looks like PROMPT 1 TIMEOUT 100 DEFAULT main LABEL main BOOT /bootsect.bin -- Karch aka Dimeneira aka Dime

Deal all, Hi. I'm a new user of isolinux. And I 'm trying to boot a WinXP installation CD with it. I extracted the bootsect, and place it into the same folder together with isolinux.bin. Here's a section of my isolinux.cfg: ... label winxp kernel xpsect.bin ... The boot splash showed fine. Unfortunately when I tried to boot it, I got the following: ISOLINUX 3.11 2005-09-02 Copyright (C) 1994-2005 H. Peter Anvin...

That system installed WinXP after Win98, that's I think why there was this bootsect.dos file, because a line C:\bootsect.dos="Windows 98" in boot.ini will boot to Win98. > Once copied to your USB device...

Is it possible for syslinux to load another syslinux with it's own configuration file found in another directory? If so, where can I find sample? Thanks in advance

Add nbdkit-floppy-plugin, “inspired” by qemu's VVFAT driver, but without the ability to handle writes. The implementation is pretty complete, supporting FAT32, LFNs, volume labels, timestamps, etc, and it passes both ‘make check’ and ‘make check-valgrind’. Usage is simple; to serve the current directory: $ nbdkit floppy . Then using guestfish (or any NBD client): $ guestfish --ro

Hi! Facing a strange problem about not being able to access the floppy drive after booting from a rescue-floppy with 2.2.x kernel on an asus p4te mainboard, i searched the net and found a bug in the bootsector of the 2.2.x kernels. Before control is redirected to the kernel, the floppy drive is shut down in a way, that freezes the FD-Controller on recent mainboards (like the ASUS P4T-E). The Syslinux-Bootsector (at least until version 1.72) uses the same method of "stopping" the floppy; this...

...s, which means parts of Eltorito booting are still present in system (somewhat like KEEPPXE). FreeDOS kernel does not show the EDD error though, but that piece of software is currently a little bit messy, so not reliable. Vmware Workstation 5 Beta1, by the way. also a syslinux bootdisk with 'bootsect.bin' seems to work perfectly, I always thought BSS was required (my mistake?). Also 2.12pre9 is missing SYSLINUX.EXE, but the .COM seems to work SYSLINUX A: (I do get a direct hardware access message though on Win2000) Bernd ----------------------------------------------------------------...

...but is limited to floppy sizes. I tried simply building a MEMDISK of 15M and loading a floppy image into that, but then I get a message indicating that the image is truncated, and the system won't boot. I've tried building a blank image from Linux using the following procedure (where bootsect.w98 is a copy of the bootsector from a bootable Win98 partition using a standard DOS MBR): dd if=/dev/zero of=/tmp/15m.img bs=1M count=15 losetup /dev/loop0 /tmp/15m.img mkdosfs /dev/loop0 (no parms. Since this is too big for a floppy, it automatically makes it hd.) dd if=/tmp/boot...
