[syslinux] Any errors in the process for creating bootable DOS image

[Michael Zhu]

Hi all,

I want to create a bootable DOS 6.22 image for
pxelinux + memdisk. The following is my steps, anyone
who knows what wrong with them?

1. Create image from a bootable floppy
    dd if=/dev/fd0 of=dosboot.img
    dd if=/dev/fd0 of=dos.bss bs=512 count=1 
    mount -o loop -t msdos dosboot.img /mnt/image
    cp dos.bss /mnt/image
    umount /mnt/image
2. config file in pxelinux.cfg folder
    LABEL dos
    KERNEL memdisk
    APPEND initrd=dosboot.img

The error message are:
    ......
    Disk is floppy, 1440 K, C/H/S = 80/2/18
    ......
    Booting ...

    Non-System disk or disk error
    Replace and press any key when ready

Any help is appreciated.

Michael Zhu
