[syslinux] can not boot DOS image

[Miller, Shao]

Good day LÉVAI Dániel,

You asked about using a 1.44 MB floppy disk image using the FDIMAGE keyword in your PXELINUX config-file.  In syslinux/doc/comboot.txt, we see a hint that FDIMAGE is only relevant for ISOLINUX.

Please use MEMDISK, as follows:

$ cat pxelinux.cfg/default
[...]
    LABEL update_bios_img
      MENU LABEL ^BIOS Update (img)
      KERNEL memdisk
      INITRD ibm_fw_bios_m9e144a_anyos_i386.img
[...]

You will need for the "memdisk" file (from syslinux/memdisk/memdisk) to be available in your TFTP service directory.

Good luck!
