Syslinux - Sep 2006 - problem booting msdos with memdisk

I have the same problem. I can not boot a floppy disk. Once I did it but no
longer I can do this. I think there is some problem in the new versions of
PXELinux.

Try using grub4dos.  I have had exactly the same problem as you on all IBM
Thinkpad machines with syslinux's memdisk - Dell machines work fine though. 
I reported this problem almost 2 years ago but no solution was found then.

Use grub4dos v 0.4.1 - it is the most stable at the moment.  Here is an example
syslinux.cfg:

default grub.exe --config-file="map --mem dosfloppy.gz (fd0); map --hook;
chainloader (fd0)+1; rootnoverify (fd0); boot"

Good luck,
Quinn

What's the last version that worked, and what's the first version that 
didn't work?  Make sure you test intervening prereleases to narrow it 
down to a possible code change.
