    Hello!

    Is there a way I can compress those dos.img files?

    Because program2.exe has 200MB (it was running through pendrive, not floppy).
    But if I make an image of the entire pendrive, the dos2.img will have 1GB (which is my pendrive's total memory capacity)!!

    Is there a way to solve this?

    PS: I don't have floppy drives in my laptop

    Thank you

    ok, the first program could fit on a floppy, right?
    If you don't have a floppy drive, you can
    1. download a floppy image (dos622 or windows98se)
    you can try this site: MS-DOS Boot Disk Download | AllBootDisks - Providing Free Boot Disks from MS-DOS to Windows XP.
    2. mount the image and place your program in it
    do this as root (and you might want to do that on a copy of the downloaded file):
    cp dos.6.22.img dos1.img
    mkdir -p /mnt/floppy
    mount -o dos1.img /mnt/floppy
    cp program1.exe /mnt/floppy
    umount /mnt/floppy
    3. place the resulting dos1.img on your (mounted usb drive)

    As for the other program, the floppy image solution is not possible
    You could create a bootable iso image with mkisofs
    but there's no guarantee
    that memdisk would be able to completely boot the iso

    you might try this forum as they deal a lot with dos/windows
    Boot Land

    good luck

    Hello!

    I tried your suggestions, but I still have some problems.

    I can't seem to boot from the image files I downloaded from Bootdisk.Com

    I have a 622c.img file and a winme.img file.

    622c.img stops at: Loading MS-DOS...
    winme.img stops at: Starting Boot... (or something... sorry can't remember).

    Here is my syslinux.cfg file:


    PROMPT 0
    TIMEOUT 30
    DEFAULT /boot/vesamenu.c32
    MENU BACKGROUND /boot/splash.png
    .
    .
    .
    .
    .
    .
    LABEL DOS
    MENU LABEL Boot into DOS
    KERNEL /boot/memdisk
    APPEND initrd=/boot/images/winme.img
    TEXT HELP

    Help:

    Loads MS-DOS.
    ENDTEXT

    The files I have in the pendrive are:

    boot:

    -rwxr-xr-x 1 ADFC root 1884 2009-07-13 00:42 syslinux.cfg~


    What am I doing wrong, and why can't I boot from any dos image using memdisk?
    Did I forget to include some file in the pendrive or something?


    Thank you

    I haven't tried those. I do know that the freedos image I have
    (it's a compressed image called balder10.imz) does boot.

    Have you tried the ones that don't use a ram file (try to download
    either dos622 or 98se without RAM)?
    here's the direct link to 98se without RAMdrive:

    Hello vonbiber.

    I tried your image (W98 without RAMDrive).
    Same thing.

    It's strange.

    I have also tried in a different laptop and I got the same errors.

    I now think that I am doing something wrong, or that there is some compatibility issue between syslinux and my BIOS.

    Still investigating.
    If you vonbiber (or anyone in the form), have more suggestions please don't hesitate to share them.

    It's just that I don't give up that easy.

    Thank you
