Syslinux - Apr 2004 - isolinux - memdisk problems

I had posted the problem described below about two weeks ago,
and I would like to add some odd behaviour even on machines where
the zip image is loaded correctly (without divide by zero).

If I call DOS fdisk, when booted from the image, fdisks asks
if it should enable the large disk support and the returns
immediately to the command prompt.

regards

Subject: Isolinux - Memdisk problems - divide by zero after booting


I'm trying to switch from a standard floppy emulation
rescue disk (PQ-Magic & Ghost) to a no emulation
large floppy using isolinux & memdisk. I finally
got the CD booting on two systems (see below)
but on a third system I get a divide by zero message
and/or other error from DOS, which is starting
to boot correctly. It appears to happen during
loading the drivers in config.sys. It is an
AS-Rock K7VT2 motherboard with originally a
slightly outdated AMI BIOS (09/24/2002)
62-P100-001368-00101111-04201-VIA_K7-K7VT2100
but the same thing happens with the current BIOS
62-P130-001368-00101111-04201-VIA_K7-K7VT2130
BTW, this system boots nicely from the 100MB 
IDE-Zip (which is repartitioned to 10MB),
from which I prepared the gzipped image.
The zip is jumpered to floppy mode, i.e.
it ignores the partition table, although
present.

On other systems this does not occur, it works
correctly on a DK440LX with Phoenix BIOS and
and FSC MT8 MB (the latter is a Phoenix Vs. 4.06
Rev. 1.16.1107).

What can I do to trace down the problem?
Is there a more verbose memdisk kernel?

regards & thanks in advance for any help

This menu system is great Murali and Peter, Thanks!

I have some problems though. It crashes when I have a menu full of
entries that are longer than the screen, is there a way to make the
menu scroll when there are alot of entries. Actually it crashes
anytime a menu goes off screen, like with 5 submenus it falls off
the right of the screen and crashes. In that case is there a way
to make it bounce back the other way when it hits the edge of the
screen.

Thanks for any help,
 Aaron
