[syslinux] problem booting msdos with memdisk

[Quinn Plattel]

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
