[syslinux] Is it possible to chainload EXTLINUX from GRUB?

[Gavin D. Smith]

I installed extlinux on a (logical) partition, using a command like 
"extlinux -i /mnt/partition". I want to boot to that partition, so put 
something like

root (hd0, 4)
chainloader +1
boot

in an entry in GRUB. I think that SYSLINUX gets loaded but it gives a "Boot 
error" message and halts. Does anyone know if I am going about this the 
right way or if there is something else I should be trying?

Thanks,

Gavin Smith
