Hello Eileen,

because of the *. ima extension I suppose you use using WinImage you create
your DOS Bootdisk. If you want to use ghost for imaging I suppose you don't
use a 1.4 MB Floppyimage. How do you you create your boot image and what's
the size.

To narrow your problem:
* Try first to use a standard 1,4 MB floppy that also boots from floppy
drive.
* Don't use the DOS-Version of Windows ME (Freedos, MS Dos 5.0 till Win 98
SE would bee ok) because this version will not boot via pxe.
* If you use himem in your config.sys, use the /testmem:off switch
(otherwise this can overwrite pxe/memdisk).
* Make sure (if possible at least for testing purpose) that a floppy drive
is attached to and activated in bios of the pxe-client (because of buggy
pxe implemetations).
* If you want to create a 2,8MB floppy image with winimage, read first a
bootable normal 1,4 MB floppy, change format in WinImage to 2,8MB and add
then extra Files to image.
* If you aren't experienced this WinImage and pxelinux/memdisk don't use
master boot images greater 2,8 MB
* If you create boot floppies greater then 2,8MB with Winimage your config
file memdisk needs the floppy and c,h,s parameters (normaly something like
c=225 s=36 h=4,8 or 16).
* Images greater 2,8MB must be uncompressed (ima) images, the smaller ones
can use compressed (imz) format.

If you need a greater bootimage please email me personaly and I can send
you a master image and the corresponding template for your config file
(just copy your files into this).

Mit freundlichen Gruessen - Yours sincerely

Peter Leenders

Hello,

I am a *nix newbie

I am trying to boot a DOS boot disk using PXE (to Ghost on windows
images).

We have an existing PXE server which successfully serves out PXElinux and
Fedora builds based on that but my floppy disk image with memdisk isn't
working

I have tried a few different floppy images which people have posted as
ones that work for them but I doubt the disk is the problem as the hang
occurs before memdisk itself seems to have even loaded:

Loading memdisk.....
Loading image.img .............
Loading Ready

and then nothing more....

I only found one other post with the same symptoms.
http://syslinux.zytor.com/archives/2002-April/000346.html

The guy who set up the server says that the versions of isolinux etc are
the latest.



This is from my config file (I tried all these variations but the same
result):


label 20
kernel memdisk keeppxe
append initrd=test.ima floppy

label test
kernel memdisk
append initrd=dos/bart.img keeppxe

label a
kernel memdisk
append initrd=dos/net.img floppy

label b
kernel memdisk
append initrd=dos/netlg.ima floppy

label c
kernel memdisk
append initrd=dos/net.img raw

label d
kernel memdisk
append initrd=dos/netlg.ima raw

label e
kernel memdisk
append initrd=dos/netlg.ima floppy raw


Any ideas much appreciated!

Hello Ian,

sorry that I was a bit inaccurate.

If one uses WinImage to create floppy bootimage you have the option to save
the image as compressed or uncompressed image. Memdisk can handle this
(special?) format of WinImage compressed *. imz files for floppy images
smaller/equal than 2,8MB. My experience was that memdisk can not handle the
*.imz format for greater superfloppy images (no patitiontable).

I guess for harddisk-type images - with partion table - a later compression
with gzip will work. I did only a few test with usbstick images and this
was quite some time ago.

I don't know if it is possible to compress a superfloppy image later with
gzip - would be nice to hear if some has used this and it works.

Yours sincerely
Peter Leenders

No, that's because larger images (except LS-120 images of the exactly
right size) need the geometry specified on the command line; geometry is
determined after decompression. As long as the images are gzipped it
shouldn't matter.

Many thanks to Peter and Ian for their help!

I put the older version of Memdisk that Ian sent me in place of the file
on the server and it started to actually load the images. Some of my
images didn't work and some did - the one I settled on in the end was a
(2.8MB) copy of the universal bootdisk from http://www.netbootdisk.com/
which is a bit slower to load than some but supports lots of network
cards.

I actually had tried re-downloading and recompiling the latest version of
Memdisk so I don't know if there is something about the version or it's to
do with what I (and the guy before me who actually knows about Unix) did.

Anyway, thank you

This is a regression, though, which makes me concerned.

Could you try syslinux 3.52-pre4 and see if it works? Also, what is the
older version that you say works?

OK,

Back to that Unix Newbie thing I mentioned - how do I tell the version...

Ian sent it to me so I didn't download it.

In the download of the 3.52-pre4 version - there is a file called
'memdisk' - is that a compiled file - can I just copy it across?

If that doesn't work, it might be necessary to bisect -- meaning doing a
binary search on the intervening versions. 2.08->3.51 is a
mind-bogglingly large step.
